California Proposition 65 Warning

WARNING: This product can expose you to chemicals, including lead, which are known to the State of

California to cause cancer and birth defects or other reproductive harm. For more information go to www.

P65Warnings.ca.gov. P65 details at forneyind.com. Wash hands after use.

EMF Information

Welding current, as it flows through the welding cables, will cause electromagnetic fields. There has been and still

is some concern about such fields. However, after examination, the committee of the National Research Council

concluded that: “The body of evidence, in the committee’s judgment, has not demonstrated that exposure to

power-frequency electric and a magnetic field is a human health hazard.” However, studies are still going forth

and evidence continues to be examined. Until the final conclusions of the research are reached, you may wish to

minimize your exposure to electromagnetic fields when welding.

To reduce magnetic fields in the workplace, use the following procedures:

1. Keep electrode and ground cables close together by twisting or taping them when possible.

2. Arrange cables to one side and away from the operator.

3. Do not coil or drape cables around your body.

4. Keep welding power source and cables as far away from operator as practical.

5. Connect ground clamp to workpiece as close to the cut or weld as possible.

ABOUT PACEMAKERS & HEARING AIDS:

Pacemaker and hearing aid wearers consult your doctor first. If cleared by your doctor, then following the above

procedures is recommended.

Personal Protection

Welding processes of any kind can be dangerous not only to the operator but to any person situated near the

equipment, if safety and operating rules are not strictly observed.

THE WELDING ARC PRODUCES VERY BRIGHT ULTRAVIOLET AND INFRARED

LIGHT. THESE ARC RAYS WILL DAMAGE YOUR EYES AND BURN YOUR SKIN IF

YOU ARE NOT PROPERLY PROTECTED. To reduce the risk of injury from arc rays, read,

understand, and follow the safety instructions. In addition, make certain that anyone else that uses this welding

equipment, or is a bystander in the welding area understands and follows these safety instructions as well.

Helmets and filter should conform to ANSI Z87.1 stan dards.

• Do not look at an electric arc without proper protection. A welding arc is extremely bright and intense and, with

inadequate or no eye protection, the retina can be burned, leaving a permanent dark spot in the field of vision.

A shield or helmet with a #10 shade filter lens (minimum) must be used.

• Provide bystanders with shields or helmets fitted with an appropriate shade filter lens.

• Do not strike a welding arc until all bystanders and you (the welder) have welding shields and/or helmets in

place.

• Do not wear a cracked or broken helmet and replace any cracked or bro ken filter lenses immediately.

• Do not allow the uninsulated portion of the MIG gun to touch the ground clamp or grounded workpiece to

prevent an arc flash from being created on contact.

• Wear protective clothing. The intense light of the welding arc can burn the skin in much the same way as the

sun, even through light-weight clothing. Wear dark clothing of heavy material. The shirt worn should be long

sleeved and the collar kept buttoned to protect chest and neck.

• Protect against reflected arc rays. Arc rays can be reflected off shiny surfaces such as a glossy painted surface,

aluminum, stainless steel, and glass. It is possible for your eyes to be injured by reflected arc rays even when

wearing a protective helmet or shield. If welding with a reflective surface behind you, arc rays can bounce

off the surface and off the filter lens. It can get inside your helmet or shield and into your eyes. If a reflective

background exists in your welding area, either remove it or cover it with something non-flammable and non-

reflective. Reflective arc rays can also cause skin burn in addition to eye injury.

WWW.FORNEYIND.COM

• Flying sparks can injure. Wear proper safety equipment to protect eyes and face. Shape tungsten electrode on

grinder wearing proper protection and in a safe location. Keep flammables away and prevent fire from flying

sparks.

FUMES, GASSES, AND VAPORS CAN CAUSE DISCOMFORT, ILLNESS, AND

DEATH! To reduce the risk, read, understand, and follow the safety instructions. In addition, make certain that

anyone else that uses this welding equipment or is a bystander in the welding area, understands and follows these

safety instructions as well.

• Read and understand manufacturers Safety Data Sheets (SDS) and Material Safety Data Sheets (MSDS).

• Do not weld in an area until it is checked for adequate ventilation as described in ANSI standard Z49.1. If

ventilation is not adequate to exchange all fumes and gasses generated during the welding process with fresh

air, do not weld unless you (the welder) and all bystanders are wearing air-supplied respirators.

• Do not heat metals coated with, or that contain, materials that produce toxic fumes (such as galvanized steel),

unless the coating is removed. Make certain the area is well ventilated, and the operator and all bystanders are

wearing air-supplied respirators.

• Do not weld, cut or heat lead, zinc, cadmium, mercury, beryllium, antimony, cobalt, manganese, selenium,

arsenic, copper, silver, barium, chromium, vanadium, nickel, or similar metals without seeking professional

advice and inspection of the ventilation of the welding area. These metals produce extremely toxic fumes which

can cause discomfort, illness and death.

• Do not weld or cut in areas that are near chlorinated solvents. Vapors from chlorinated hydrocarbons, such

as trichloroethylene and perchloroethylene, can be decomposed by the heat of an electric arc or its ultraviolet

radiation. These actions can cause phosgene, a highly toxic gas to form, along with other lung and eye-

irritating gasses. Do not weld or cut where these solvent vapors can be drawn into the work area or where the

ultraviolet radiation can penetrate to areas containing even very small amounts of these vapors.

• Do not weld in a confined area unless it is being ventilated or the operator (and anyone else in the area) is

wearing an air-supplied respirator.

• Stop welding if you develop momentary eye, nose, or throat irritation as this indicates inadequate ventilation.

Stop work and take necessary steps to improve ventilation in the welding area. Do not resume welding if

physical discomfort persists.

Fire Prevention

FIRE OR EXPLOSION CAN CAUSE DEATH, INJURY, AND PROPERTY DAMAGE!

To reduce these risks, read, understand and follow the safety instructions. In addition, make certain that anyone

else that uses this welding equipment, or is a bystander in the welding area, understands and follows these safety

instructions as well. Remember: arc welding by nature produces sparks, hot spatter, molten metal drops, hot slag

and hot metal parts that can start fires, burn skin and damage eyes.

• Do not wear gloves or other clothing that contains oil, grease, or other flammable substances.

• Do not wear flammable hair preparations.

• Do not touch the hot weld bead or weld puddle until fully cooled.

• Do not weld in an area until it is checked and cleared of combustible and/or flammable materials. Be aware

that sparks and slag can fly 35 feet and can pass through small cracks and openings. If work and combustibles

cannot be separated by a minimum of 35 feet, protect against ignition with suitable, snug-fitting, fire resistant,

covers or shields.

• Do not weld on walls until checking for and removing combustibles touching the other side of the walls.

• Connect the ground cable to the workpiece as close as possible to the welding area. Do not connect ground

cables to building framing or other locations away from the welding area. This increases the possibility of

welding current passing through alternate circuits, creating fire hazards and other safety hazards.

• Do not weld, cut, or perform other such work on used barrels, drums, tanks, or other containers that had a

flammable or toxic substance. The techniques for removing flammable substance and vapors, to make a used

container safe for welding or cutting, are quite complex and require special education and training.

• Do not strike an arc on a compressed gas or air cylinder, and never allow any electrically “hot” parts to touch a

cylinder. Doing so will create a brittle area that can result in a violent rupture immediately or at a later time as a

result of rough handling.

• Ensure any compressed gas cylinders in the work area have properly operating regulators rated for the gas

and pressure used. All hoses, fittings, etc. should be in good condition.

• Do not stand in front of or put your head or face in front of a cylinder valve outlet when opening the valve.

• If a cylinder is not in use or connected for use, keep a valve protection cap in place to protect the valve.

• Keep cylinders upright and securely chain them to a fixed support to prevent tipping.

WWW.FORNEYIND.COM

• Keep cylinders away from areas where they may be subjected to physical damage or accidentally struck. Keep

them a safe distance from any source of flame, sparks, or heat.

• Do not weld or cut in an area where the air may contain flammable dust (such as grain dust), gas, or liquid

vapors (such as gasoline).

• Do not handle hot metal, such as the workpiece or electrode stubs, with bare hands.

• Wear leather gloves, heavy long sleeve shirt, cuff-less pants, high-topped shoes, helmet, and cap. As necessary,

use additional fire-resistant protective clothing to cover and protect the upper and lower body. Hot sparks or

metal can lodge in rolled up sleeves, pant cuffs, or pockets. Sleeves and collars should be kept buttoned and

pockets eliminated from the shirt front.

• Have fire extinguisher equipment handy for immediate use. A portable chemical fire extinguisher, type ABC, is

recommended.

• Wear ear plugs when welding overhead to prevent spatter or slag from falling into ear.

• Make sure welding area has a good, solid, safe floor, preferably concrete or masonry, not tiled, carpeted, or

made of any other flammable material.

• Protect flammable walls, ceilings, and floors with heat resistant covers or shields.

• Check welding area to make sure it is free of sparks, glowing metal or slag, and flames before leaving the

welding area.

• Wear garments free of oil or other flammable substances such as leather gloves, thick cotton shirts with no

synthetic materials, cuff-less trousers, closed toed shoes. Keep long hair pulled back.

• Remove any combustibles such as lighters and matches before doing any welding.

• Follow requirements in OSHA and NFPA for hot work and have an extinguisher nearby.

High Frequency Radiation

• High Frequency (H.F) can interfere with radio navigation, safety services, computers and communication

equipment.

• It is the user’s responsibility to have a qualified electrician promptly correct any interference problem resulting

from the installation. Electrician should regularly check and maintain installation.

• Stop using the equipment if notified by the FCC about interference.

• Keep H.F. source doors and panels tightly shut and keep spark gaps at correct setting.

Arc Welding

• Computers and computer driven equipment can be harmed with electromagnetic energy.

• Be sure all equipment is compatible with electromagnetic energy.

• Keep welding cables short to reduce interference.

• Follow manual to install and ground machine.

• If interference continues, shield the work area or move the welding machine.

WARNING: ELECTRIC SHOCK CAN KILL! To reduce the risk of death or serious injury from shock,

read, understand, and follow the safety instructions. In addition, make certain that anyone else who uses this

welding equipment, or who is a bystander in the welding area understands and follows these safety instructions as

well.

IMPORTANT! TO REDUCE THE RISK OF DEATH, INJURY, OR PROPERTY

DAMAGE, DO NOT ATTEMPT OPERA TION of this welding equipment until you have read and

understand the following safety summary.

• Do not, in any manner, come into physi cal contact with any part of the welding current circuit. The welding

water spray.

• Do not carry coiled welding cables around shoulders, or any other part of the body, when they are plugged

into the welder.

• Do not modify any wiring, ground connections, switches, or fuses in this welding equipment.

• Wear welding gloves to help insulate hands from welding circuit.

• Keep all liquid containers far enough away from the welder and work area so that if spilled, the liquid cannot

possibly come in contact with any part of the welder or electrical welding circuit.

• Replace any cracked or damaged parts that are insulated or act as insulators such as welding cables, INPUT

POWER CABLE, or electrode holder immediately.

• When not welding, cut wire back to contact tip or remove electrode from electrode holder.

Noise

Noise can cause permanent hearing loss. Welding processes can cause noise levels that exceed safe limits. You

must protect your ears from loud noise to prevent permanent loss of hearing.

• To protect your hearing from loud noise, wear protective ear plugs and/or ear muffs.

• Noise levels should be measured to be sure the decibels (sound) do not exceed safe levels.

Recommended Wire Diameter 0.030” (0.8mm)

Description

Your new flux core (FCAW) wire feed welder is designed for light maintenance/repair or DIY welding. It is capable

of welding sheet metal or thin plate. The welder is an inverter based DC output machine. The inverter design

provides for higher electrical efficiency and a smoother arc. This welder is capable of welding with up to 0.030”

(0.8 mm) self-shielding flux-core wire. Larger diameter wire will draw more amperage and may trip your circuit

breakers. With your new welder, you can weld sheet metal from 18 gauge up to 3/16-inch thick with a single pass.

You can weld up to 1/4-inch steel with beveling and multiple pass techniques.

BE SURE TO LOCATE THE WELDER ACCORDING TO THE FOLLOWING GUIDELINES:

• In areas free from moisture and dust;

• In areas with ambient temperature between 30° to 90°F;

• In areas free from oil, steam and corrosive gases;

• In areas not subjected to abnormal vibration or shock;

• In areas not exposed to direct sunlight or rain;

• Place at a distance of 12” or more from walls or similar obstructions that could restrict natural air flow for

cooling.

Before you make any electrical connection, make sure that the ON/OFF SWITCH (8) is OFF, power supply voltage

and frequency available at site are those stated in the ratings label of your welder.

The main power supply voltage should be within ±10% of the rated main power supply voltage. Too low a power

supply voltage may cause poor welding performance. Too high a power supply voltage will cause components to

overheat and possibly fail. The welder outlet must be:

• Correctly installed, if necessary, by a qualified electrician;

• Correctly grounded (electrically) in accordance with national and local regulations;

• Connected to an electric circuit that is rated for sufficient amperage per the ratings label of your welder.

If you are unsure of any of the above, have your outlet inspected by a qualified electrician before using the welder.

NOTE:

• Periodically inspect INPUT POWER CABLE (9) for any cracks or exposed wires. If it is not in good condition,

have it repaired by a Service Center.

• Do not cut off the grounding prong or alter the plug in any way. Only use the included adapter between the

welder’s INPUT POWER CABLE and the power source receptacle.

• Do not violently pull the INPUT POWER CABLE to disconnect it from power outlet.

• Do not lay material or tools on the INPUT POWER CABLE. The INPUT POWER CABLE may be damaged and

result in electrical shock.

• Keep the INPUT POWER CABLE away from heat sources, oils, solvents or sharp edges.

• Do not use this welder on a circuit with a Ground Fault Circuit Interrupter (GFCI) on it. GFCIs are tripped by

welding arcs and your welding operations will be interrupted regularly.

Using the 20 Amp – 15 Amp Plug Adapter

If a 20A outlet (with 30A circuit breaker) is not available, you can connect your 140 FC-i Forney Easy Weld

™

welder to 15A outlet (with a 20A breaker) using the plug adapter. When using the plug adapter, use lower power

settings on the machine to avoid frequent circuit breaker trips. At maximum settings, the machine will draw more

than 20 amps regularly.

Generators

This welder can be operated from an AC generator. Ensure that the generator can supply a minimum of 4,000

watts of continuous output. The generator must not have an auto-idle fuel saving feature or must have the option to

turn auto-idle off. The generator must run at full speed at all times while your welder is plugged into it or you risk

damaging your welder. Any other power draws on the generator or anything that reduces the generator RPM may

damage your welder.

Extension Cords

For optimum welder performance, an extension cord should not be used unless absolutely necessary. If necessary,

care must be taken in selecting an extension cord appropriate for use with your specific welder.

Select a properly grounded extension cord that will mate directly with the AC power source receptacle and the

welder INPUT POWER CABLE (9). Only use the included adapter between the welder’s INPUT POWER CABLE

and the extension cord. Make certain that the extension cord is properly wired and in good electrical condition.

Extension cords must fit the following wire size guidelines:

• #12 AWG or larger wire

• Do not use an extension cord over 25 ft. in length.

Since the inhalation of welding fumes can be harmful, ensure that the welding area is effectively ventilated. See the

“Safety Summary” for more details (pages 5-9).

FOR YOUR SAFETY, BEFORE CONNECTING THE POWER SOURCE TO THE LINE

CLOSELY FOLLOW THESE INSTRUCTIONS:

• An adequate two-pole breaker must be inserted before the main outlet. This breaker must be equipped with

time-delay fuses.

• When working in a confined space, the welder must be kept outside the welding area and the ground cable

should be fixed to the workpiece. Never work in a damp or wet confined space.

• Do not use damaged INPUT POWER CABLE (9) or welding cables.

• The welding gun should never be pointed at the operator or other people.

• The welder must never be operated without its panels attached. This could cause serious injury to the operator

and could damage the equipment.

Welder Layout and Controls

1. HANDLE

Rugged, top mounted handle allows for easy transport of your welder and a place to wrap your cables.

2. INPUT VOLTAGE INDICATOR LED

This will be illuminated when input voltage to the machine is present and the ON/OFF SWITCH (8) is in the ON

position.

3. FAULT/THERMAL OVERLOAD INDICATOR LED

This

will be illuminated under the following conditions:

a. The duty cycle of the machine has been exceeded or air flow is blocked. The fan will continue to run until

the machine has cooled, but output power will be disabled. Ensure that the cooling fan is running and that

there are 12 inches of clearance around all vents. When the LED turns off, welding power will be enabled

again.

b. The input voltage is outside of the acceptable range. If this indicator remains illuminated for more than 10

minutes, it is likely that there is an input voltage problem.

4. VOLTAGE ADJUSTMENT KNOB

Use this dial to adjust the arc voltage or “heat” of your welder (1 is the lowest and 10 is the highest). Different

materials and material thickness will require different voltage settings. You will need to adjust your voltage

accordingly for different welding conditions. By properly adjusting your voltage settings and wire feed speed,

you will produce clean welds. (Refer to the Suggested Settings Chart on the inside panel of the welding

machine). NOTE: this is a scale, not actual voltage.

5. WIRE FEED ADJUSTMENT KNOB

Use this dial to adjust the speed at which the welder feeds wire to the gun (1 is the slowest and 10 is the

highest). You will need to adjust or “tune-in” your wire speed for different welding conditions (thickness of

metals, metal type, wire size, etc.) Refer to setup chart for a starting point. When the wire speed is properly

“tuned-in” the welding wire will melt into the material you’re welding as quickly as it is fed through the welding

gun. This welder operates best between 5-7 on this dial, and will do well in most conditions in this range.

NOTE: this is a scale, not actual wire feed speed.

6. MIG GUN AND CABLE

The welding gun controls the delivery of the welding wire to the material to be welded. The welding wire is fed

through the welding cable and welding gun when the welding gun trigger is pulled. You will need to install a

contact tip and welding nozzle to the end of the welding gun prior to welding.

7. GROUND CLAMP AND CABLE

Attaching the ground clamp to your work piece completes the welding current circuit. You must attach the

ground clamp to the metal you are welding. If the ground clamp is not connected to the metal work piece you

intend to weld, the welder will not have a completed circuit and you will be unable to weld. A poor connection

at the ground clamp will create an erratic arc and may damage your welder. Scrape away dirt, rust, scale, oil

or paint before attaching the ground clamp.

8. ON/OFF SWITCH

This switch turns the welder ON and OFF. (Make sure the power switch is in the OFF position before performing

any maintenance on the welder.)

9. INPUT POWER CABLE

This is a standard, grounded 120 volt power cord. (Make sure you are using a properly grounded 120 Volt

AC, single phase power source with 20 amp time-delay (“slow-blow”) breakers.)

Selecting the Welding Wire

This welder uses only four or eight-inch spools of 0.030-inch (0.8mm) self- shielding flux-core wire. Steel from 24

gauge up to 1/4-inch thick can be welded with 0.030-inch wire. Larger diameter wire will be less capable with

thicker materials, will not increase your deposition rate, and may over-draw your AC power source.

NOTE:

• If a spool has developed heavy oxidation, the only solution to the problem is to discard the spool of wire.

• If you have an oxidized spool of wire, do not discard it until you have unspooled a few turns of wire to see if

the wire farther down on the spool is in usable condition. If it is not, discard the spool.

NOTE: THIS MACHINE IS NOT AN APPROPRIATE POWER SOURCE FOR WELDING ALUMINUM.

Installing the Welding Wire

ENSURE ELECTRICAL SUPPLY IS DISCONNECTED. Before proceeding, remove the nozzle and

the contact tip from the gun.

WARNING: ELECTRIC SHOCK CAN KILL! Always turn the ON/OFF SWITCH (8) to the OFF

position and unplug the welder’s INPUT POWER CABLE (9) from the AC power source before installing wire. When

the gun trigger is depressed, the drive rolls, spool of wire, wire being fed, and electrode are all electrically live (hot).

INSTALLING 4-INCH SPOOL (SEE FIGURE FOR PART IDENTIFICATION):

1. Open the access panel.

2. Unscrew and remove the wire spool retention cap used for 8-inch spools (A) and store it someplace safe.

3. Remove the spindle adapter for 8-inch spools (B) and store it someplace safe.

4. Remove the nut (C), spring (D), and washers (E).

5. Remove the outer wrapping from the included spool of wire and then find the leading end of the wire (it

goes through a hole in the outer edge of the spool and is bent over the spool edge to prevent the wire from

unspooling) but do not unhook it yet.

6. Place the spool on the WIRE SPOOL SPINDLE (10) in such a manner that when the wire comes off the spool,

it will look like the illustration above. The wire should unspool from the bottom, and the spool will rotate in a

counter-clockwise fashion.

7. Place the washer, wire spool locking bushing, spring, and nut back in place.

8. Proceed to “FEEDING WIRE THROUGH THE MIG GUN” instructions below.

INSTALLING 8-INCH SPOOL (SEE FIGURE FOR PART IDENTIFICATION):

1. Open the access panel.

2. Unscrew and remove the wire spool retention cap (A).

a. NOTE: If the wire spool retention cap and the spindle adapter for 8-inch spools (B) are not present (machine

was last used with a 4-inch spool) put the spindle adapter for 8-inch spools back in place.

3. Make sure all of the components used for a 4-inch spool are still in place. They are necessary for 8-inch spools

as well (nut (C), spring (D), and washers (E)).

4. Remove the outer wrapping from the spool of wire and then find the leading end of the wire (it goes through a

hole in the outer edge of the spool and is bent over the spool edge to prevent the wire from unspooling) but do

not unhook it yet.

5. Place the spool on the spindle adapter for 8-inch spools in such a manner that when the wire comes off the

spool, it will look like the illustration above. The wire should unspool from the bottom, and the spool will rotate in

a counter-clockwise fashion.

a. NOTE: Be sure the alignment pin near the base of the spindle adapter for 8-inch spools is inserted in the

corresponding hole on the spool.

6. Thread the wire spool retention cap back in place.

FEEDING WIRE THROUGH THE MIG GUN:

1. Unhook the wire and hold the wire end and the spool in one hand. With the other hand tighten the nut (C) just

enough so that when the spool is released it does not spin freely and uncoil the wire. Tightening the nut too

much may cause inconsistent wire feeding. Leaving it too loose will allow the wire to uncoil freely from the spool,

leaving a mess of wire in the cabinet.

2. While holding the wire in place, use a wire cutter to cut the bent end of the wire so that only a straight end

remains.

3. Continue to hold the wire end in one hand and release the drive roll pressure arm (I) by pulling the pressure arm

adjustment knob (G) toward you. Hold the drive roll pressure arm up off of the drive roller and insert the leading

end of the wire into the inlet guide tube (H). Push the wire across the drive roller (J) and into the gun assembly

approximately six inches.

4. Line the wire up in the outside groove of the drive roller and allow the drive pressure arm to drop onto the

drive roller. Pull the pressure arm adjustment knob back over the pressure arm and tighten (turn clockwise) the

pressure adjusting knob until the pressure roller is applying enough force on the wire to prevent it from slipping

out of the drive assembly. NOTE: Too much pressure will cause wire to feeding problems and may burn out the

wire feed motor.

5. Let go of the wire.

6. Remove the nozzle (K) and contact tip (L) from the end of the gun assembly (M).

7. Plug the welder’s INPUT POWER CABLE into the AC power source. Adjust the settings on the front panel per the

setup chart on the inside panel door of the welding machine according to the size of the wire and workpiece.

8. Pull the trigger on the MIG gun to feed the wire through the gun assembly. Check if the drive roll is slipping on

the wire and increase pressure on the pressure arm adjustment knob if necessary.

9. When at least an inch of wire sticks out past the end of the gun, release the trigger.

10. Slide the contact tip (L) over the wire protruding from the end of the gun (M). Screw the contact tip into the end

of the gun and hand tighten securely.

11. Install the nozzle (K) on the gun assembly.

WWW.FORNEYIND.COM

12. Cut off the excess wire that extends past the end of the nozzle.

13. Fine tune the wire drive pressure with the pressure arm adjustment knob (G).

a. Turn the wire drive pressure adjustment knob clockwise, increasing the drive pressure until the wire seems to

feed smoothly without slipping. NOTE: If TOO MUCH pressure is applied you can crush the wire and create

wire feeding problems. If TOO LITTLE pressure is applied, the wire will slip on the drive rolls and wire will not

feed.

b. When the drive pressure is set correctly, there should be no slippage between the wire and the drive roller.

But if an obstruction occurs along the wire feed path, the wire should then slip on the drive roller. This can

be checked by squeezing the wire between two fingers with moderate force as it comes out of the gun. If this

stops the wire from feeding, increase pressure until the wire feeds through your fingers without issue.

14. Double check your spool tension: After feeding the wire and releasing the trigger, the wire coming off the spool

should not remain under tension (in a straight line from the spool to the WIRE FEEDER (11). It should relax a

little bit and take on some of the curvature the coiled wire naturally reverts to. It should also not relax so much

that the wire begins to loosen on the spool.

CORRECT

KEEP THE GUN STRAIGHT. WHEN FEEDING A NEW WIRE THROUGH THE LINER,

MAKE SURE THE WIRE IS CUT CLEANLY (NO BURRS OR ANGLES) AND THAT

AT LEAST 1” FROM THE END IS STRAIGHT (NO CURVES). FAILURE TO FOLLOW

THESE INSTRUCTIONS COULD CAUSE DAMAGE TO THE LINER.

WHEN CHECKING THE CORRECT EXIT OF THE WIRE FROM THE GUN DO NOT

BRING YOUR FACE NEAR THE GUN. YOU MAY RUN THE RISK OF BEING

WOUNDED BY THE OUTGOING WIRE. DO NOT BRING YOUR FINGERS CLOSE

TO THE FEEDING MECHANISM WHEN WORKING! THE ROLLS, WHEN MOVING,

MAY CRUSH FINGERS. PERIODICALLY CHECK THE ROLLS. REPLACE THEM WHEN

THEY ARE WORN AND COMPROMISE THE REGULAR FEEDING OF THE WIRE.

Performance Data Plate and Duty Cycle

On the machine, there is a plate that includes all the operating specifications for your new unit. The serial number

of the product is also found on this plate.

The duty cycle rating of a welder defines how long the operator can weld and how long the welder must rest and

be cooled. Duty cycle is expressed as a percentage of 10 minutes and represents the maximum welding time

allowed. The balance of the 10-minute cycle is required for cooling.

For example, a welder has a duty cycle rating of 30% at the rated output of 90A. This means with that machine,

you can weld at 90 A output for three (3) minutes out of 10 with the remaining seven (7) minutes required for

cooling. The duty cycle of your new welder can be found on the data plate affixed to the machine. It looks like the

diagram below. Referring to the sample below, the “X” row lists duty cycle percentages while the “I

” row lists the

amp draw corresponding to the duty cycle. Various duty cycles at other amperages are listed on your data plate.

If you exceed the duty cycle of the welder, the thermal protection system will engage, shutting off all welder output.

After cooling, the thermal protector will automatically reset and the welding functions can resume. This is normal

and automatic behavior of the machine, and does not require any user action. However, you should wait at least

ten minutes after the thermal protector engages before resuming welding. You must do this even if the thermal

protector resets itself before the ten minutes is up or you may experience less than specified duty cycle performance.

CAUTION: DO NOT REGULARLY EXCEED THE DUTY CYCLE OR DAMAGE TO THE

WELDER CAN RESULT.

An important factor in making a satisfactory weld is preparation. This includes studying the process and equipment

and practicing welding before attempting to weld finished product. An organized, safe, ergonomic, comfortable,

and well-lit work area should be prepared for the operator. The work area should specifically be free of all

flammables with both a fire extinguisher and a bucket of sand available.

To properly prepare for welding with your new welder, it is necessary to:

• Read the safety precautions at the front of this manual.

• Prepare an organized, well-lit work area.

• Provide protection for the eyes and skin of the operator and bystanders.

• Attach the ground clamp to the bare metal to be welded, making sure of good contact.

• Make sure that the wire-roller groove in the roller corresponds to the diameter and type of wire being used.

• Plug the machine into a suitable outlet.

EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND

SKIN. PROLONGED EXPOSURE TO A WELDING ARC CAN CAUSE BLINDNESS

AND BURNS. NEVER STRIKE AN ARC OR BEGIN WELDING UNLESS YOU ARE

ADEQUATELY PROTECTED. WEAR FIRE RESISTANT WELDING GLOVES, HEAVY

LONG SLEEVED SHIRT, CUFF-LESS PANTS; HIGH TOPPED SHOES AND A

WELDING HELMET.

Some experience is required to adjust and use a FCAW welder. In FCAW welding, two parameters are

fundamental: the welding voltage and the wire feed speed. The resulting welding current is a result of these two

settings but is more directly related to the wire feed speed.

• Set the voltage (LEFT KNOB) (4) and wire feed speed (RIGHT KNOB) (5) to positions suitable for the thickness of

the material to be welded (See “FCAW Set-Up Chart”, page 18). Welding current varies in relationship to wire

feed speed. For low wire feed speed (RIGHT KNOB), welding current output will be low. Turning the wire feed

speed control clockwise will result in increased wire feed speed and welding current. Welding voltage should

Factors to Consider for Best FCAW Welding Results

be adjusted to match the wire feed speed/welding current. Progressively select higher voltage positions when

increasing wire speed.

Increasing welding voltage leads to a longer arc (without substantially affecting the current). Conversely, a

decreased welding voltage results in a shorter arc (the current again is not substantially changed). A change in wire

diameter results in changed parameters. A larger diameter wire will draw a higher current than a smaller diameter

wire at the same wire feed speed. If certain limits are exceeded, a satisfactory weld cannot be obtained. These are:

1. Feeding wire too fast (too high speed with regard to the welding voltage) results in pulsing within the gun. This

is because the wire electrode dips into the puddle and cannot be melted off fast enough.

2. Setting welding voltage too high (too high with regard to the wire feed speed), will result in excessive and

unstable arc. Increase the voltage even higher and the contact tip will burn.

3. Excessive wire speed can be corrected through the arc voltage increase. The limit of this adjustment depends on

the thickness of the material to be welded (a certain limit exceeded will result in burn through).

Place the gun on the joint you want to weld: the angle between the gun and the workpiece should be around 45°.

The distance between the gun and the workpiece should be about 1/2” - 5/8”. Lower your face shield and press

the gun trigger to start the arc. When the arc has struck, move the nozzle slowly from left to right along the joint.

Adjust the wire feed speed until the arc makes a “crisp” sound (experience will help you to recognize the right

sound).

• Ensure the ground clamp has a good connection to the workpiece and is connected on clean, bare metal (not

rusty or painted).

• Ensure the ground clamp has a good connection to the workpiece and is connected on clean, bare metal (not

rusty or painted).

• Load the spool of wire inside the cabinet and feed it through the WIRE FEEDER (11) into the gun (see “Installing

the Welding Wire”, page 14).

• Switch the unit ON with the ON/OFF SWITCH (8).

• Press the gun trigger to load the wire through the gun.

• Set the welding parameters:

1. Adjust wire feed speed with the RIGHT KNOB (5).

2. Adjust arc voltage with the LEFT KNOB (4).

• Touch the end of the electrode wire to the workpiece and depress the gun trigger completely. The arc will initiate

and wire will begin to feed.

NOTE: The gun for your machine includes a micro-switch trigger. This provides greater trigger reliability than

typical guns, but requires the trigger to be depressed completely to make contact. Failure to depress the trigger

completely may result in erratic arc starting and stopping.

Welding Tips:

• Always weld clean, dry and well-prepared material.

• Hold gun at a 45° angle to the workpiece with nozzle about 1/2” from the surface.

• Move the gun smoothly and steadily as you weld.

• On thin gauge material, move quickly and only weld 1/4” stitch-welds at a time to avoid melt-through.

• Avoid welding in very drafty areas. A weak, pitted and porous weld will result due to drafts blowing away the

protective welding gas.

• Keep wire and liner clean. Do not use rusty wire.

• Sharp bends or kinks in the welding cable should be avoided.

Setup for Flux-Cored Wire (FCAW) Welding

WWW.FORNEYIND.COM

This welder has been engineered to need minimal service providing that a few very simple steps are taken to properly

maintain it.

1. Keep the cabinet cover closed at all times unless the wire needs to be changed or the drive pressure needs

adjusting.

2. Keep all consumables (contact tips, nozzles, and liner) clean and replace when necessary. See “Consumable

Maintenance” (below) and “Troubleshooting” (page 20) for detailed information.

3. Replace INPUT POWER CABLE (9), ground cable, ground clamp, or gun assembly when damaged or worn.

4. Avoid directing grinding particles towards the welder. These conductive particles can build up inside the machine

and cause severe damage.

5. Periodically clean dust, dirt, grease, etc. from your welder. Every six months or as necessary, remove the side

panels from the welder and use compressed air to blow out any dust and dirt that may have accumulated inside

the welder.

6. If available, use compressed air to periodically clean the liner, especially when changing wire spools.

WARNING: DISCONNECT FROM POWER SOURCE WHEN CARRYING OUT THIS

OPERATION.

7. The wire feed drive roller will eventually wear during normal use. With the correct pressure, the idler roller must

feed the wire without slipping. If the grooves in the wire feed drive roller are worn deep enough that the idler

roller and the wire feed drive roller make contact when the wire is in place between them, the wire feed drive

roller must be replaced.

8. Check all cables periodically. They must be in good condition and not cracked.

WARNING: ELECTRIC SHOCK CAN KILL! Be aware that the ON/OFF SWITCH (8), when OFF, does

not remove power from all internal circuitry in the welder. To reduce the risk of electric shock, always unplug the

welder from its AC power source and wait several minutes for electrical energy to discharge before removing side

panels.

IT IS VERY IMPORTANT TO MAINTAIN THE CONSUMABLES TO AVOID THE NEED

FOR PREMATURE REPLACEMENT OF THE GUN ASSEMBLY.

MAINTAINING THE CONTACT TIP:

The purpose of the CONTACT TIP is to transfer welding current to the welding wire while allowing the wire to pass

through it smoothly.

Always use a contact tip stamped with the same diameter as the wire it will be used with.

1. If the wire burns back into the tip, remove the tip from the gun and clean the hole running through it with an

oxygen-acetylene torch tip cleaner or tip drill. If the burned-back wire cannot be removed, the tip will have to be

replaced.

2. With extended use over time, this hole will become worn. Increased wear on the hole causes increased resistance

in the transfer of welding current from the contact tip to the wire. This will result in less stable arc characteristics

and difficult arc starting.

CAUTION: KEEP THE NOZZLE CLEAN!

During the welding process, spatter and slag will build up inside the nozzle and must be cleaned out periodically.

Failure to clean and/or replace the nozzle in a timely fashion will cause damage to the front end of the gun assembly,

which is not replaceable. The results of the inaction may require the replacement of the entire gun assembly.

Failure to keep the nozzle adequately cleaned can result in the following problems:

A shorted nozzle results when spatter buildup bridges across the insulation in the nozzle allowing welding current to

flow through it as well as the contact tip. When shorted, a nozzle will steal welding current from the wire whenever

it contacts the grounded workpiece. This causes erratic welds and reduced penetration. In addition, a shorted nozzle

overheats the end of the gun which can damage the front-end of the gun.

TESTING FOR A SHORTED NOZZLE

Arcing between the nozzle and the workpiece always means the nozzle is shorted, but this can be hard to detect

through the lens of a welding helmet. The following testing method is another way to tell if a nozzle is shorted.

With the welder unplugged from the AC power source, touch the probes of an ohmmeter or continuity tester to the end

of the contact tip and the outside of the nozzle. If there is any continuity at all, the nozzle is shorted. Clean or replace

as needed.
