1. Protect your eyes from welding light by wearing a welder's helmet fitted

with a filter shade suitable for the type of welding you are doing. The

welding process produces intense white light, infrared and ultraviolet light,

these arc rays can burn both eyes and skin.

a. Consult the Welding Shade Guide in Appendix A for the minimum

shade to protect the eyes based on the amperage and type of welding.

2. An opaque helmet will protect against the ultraviolet or infrared light. A

helmet will also protect against ejected hot material and slag. The helmet

should protect the face, forehead, ears and neck.

3. Wear a fire-resistant head covering like a skullcap or balaclava hood to

protect your head when the faceplate is down or when using a welding

hand-held face shield.

4. Wear ventilated safety goggles beneath the welding helmet or behind the

hand-held face shield. The cooling weld bead may fragment or eject slag

that can damage the eyes, when the helmet or hand-held face shield is not

in place.

a. Eye protection equipment should comply with CSA Z94.3-07 or ANSI

Z87.1 standards based on the type of work performed.

5. Wear fire resistant earplugs when welding overhead to prevent spatter or

slag from falling into ear.

PROTECTIVE CLOTHING

1. Wear a leather apron or jacket, leather welding gloves and full foot protection.

Choose clothing fabrics that resist sparks, heat, flames and splashes of molten

material. Artificial fabrics may burn and melt, resulting in a more severe injury.

a. Wear welding capes and sleeves when performing overhead welding.

2. Do not wear clothes or protective gear that are frayed, oily or greasy as

they may ignite from the heat or ejected slag and sparks.

3. Wear thick clothes that do not expose the skin. Ultraviolet or infrared light

can burn skin with sufficient exposure.

4. Do not wear clothing that can hold hot debris or sparks such as pant cuffs,

shirt pockets or boots. Choose clothing that has flaps over pockets or wear

clothing to cover the openings such as pant legs over the boots or an apron

over the shirt.

5. Gloves shall should contain an insulating lining to protect against an

electric shock.

6. Rubber soled footwear or electrically insulated work boots are

recommended while working with a welding unit. The non- skid sole is will

also help maintain footing and balance during work.

a. Select boots with steel toe protection to prevent injury from falling

objects.

RESPIRATORS

1. Respiratory protection is needed when ventilation is not sufficient to

remove welding fumes or when there is risk of oxygen deficiency.

a. Wear a NIOSH approved respirator when working on materials that

produce dust or particulate matter.

2. Work in a confined space only if it is well ventilated or while wearing an air-

supplied respirator. Welding fumes and gases can displace air and lower

the oxygen level causing injury or death. Be sure the breathing air is safe

(See Fumes and Gases).

3. The user can take the additional precaution of informing another person in

the work area of the potential danger, so that person can watch for

indications that the user is suffering from oxygen deprivation.

PERSONAL PRECAUTIONS

Control the tool, personal movement and the work environment to avoid

personal injury or damage to the tool.

1. Do not operate any tool when tired or under the influence of drugs, alcohol

or medications.

6. Immediately replace a cracked or broken helmet or a scratched or

damaged lens filter to avoid damage to the eyes or face from arc flash or

ejected molten material.

7. Do not allow the welding stick to accidentally touch the ground clamp or

grounded work. An arc flash will result from contact and can injury the

unprepared user and bystanders.

8. Do not handle hot metal or electrode stubs with bare hands. Handling may result

in a burn injury.

9. Do not use the welding unit if personal movement is confined or if there is a

danger of falling.

10. Keep all panels and covers securely in place when operating the welding

unit.

11. Insulate the ground clamp when not connected to a workpiece to prevent

contact with any metal object.

12. Do not operate the welding unit if the torch, electrode holder, welding cable

or ground cable are wet. Do not immerse them in water. These

components and the welding unit must be completely dry before

attempting to use them.

13. Never dip the electrode in water for cooling.

14. Remove the electrode from the holder when not in use.

15. Do not point the torch or electrode holder at any body part of yourself or at

anyone else.

16. Do not use a welding unit to thaw frozen pipes.

17. Insulate yourself from the work and the ground using dry insulation. Make

certain that the insulation is large enough to cover your full area of physical

contact.

18. When not welding, make certain that no part of the electrode circuit is touching

the workpiece or the ground. Accidental contact can cause overheating and

create a fire hazard.

19. Maintain good ventilation of the louvers on this equipment. Good

ventilation is of critical importance for the normal performance and service

life of this equipment.

20. When working above floor level, use a safety belt to protect yourself from a

fall should you get a shock.

21. The electrode, electrode reel, welding head, nozzle and semiautomatic

welding torchs are electrically ‘hot’ when the welding unit is in

semiautomatic or automatic wire welding mode.

FIRE AND EXPLOSION PRECAUTIONS

Arc welding can produce sparks, hot slag or spatter, molten metal drops and hot

metal parts that can start fires.

1. Clear the floor and walls of an area of all combustible and/or flammable

materials up to 39 ft (12 metres) away from the welding unit. Hot debris

ejected during welding can land at a considerable distance away. Solid

floors of concrete or masonry is the preferred working surface.

a. Cover any combustible material with fire resistant covers or shields, if

it cannot be removed. The covering must be tight and should not

leave openings for sparks or ejected slag to enter.

b. Check both sides of a panel or wall for combustible material. Remove

the combustible material before welding.

2. A combustible floor should be protected with a fire resistant covering.

Alternatives are to spray the floor with water to keep it wet for the duration

of the welding or cover with damp sand. Care must also be taken to avoid

an electric shock when this is done. A combustible floor directly laid onto

concrete does not need to be sprayed with water.

3. Seal cracks and openings to adjacent areas that a spark or slag can enter.

Seal any openings found with a fire-resistant cover. Shut doors and windows

that do not provide ventilation or erect protective screens in front of them

when possible.

4. Avoid welding near hydraulic lines or containers containing flammable

contents.

5. Do not perform any welding work on containers that held flammable or

toxic substance, until they are cleaned by a person trained in removing

toxic and flammable substances and vapours per the American Welding

Standard AWS F4.1.

8785115 200A Multi-Process Welder with LCD Display V4.0

10 For technical questions call 1-800-665-8685

6. Open a container before performing any welding work on it. The heat

generated by the welding process will cause the air and gases to expand.

The internal pressure may cause a sealed or closed container to rupture,

possibly causing an injury or death.

7. Do not weld pipes or metal that are covered in combustible material or in

contact with combustible structure such as a wall. Only weld if the

covering can be safely removed.

a. Follow all safety precautions and legal requirements before welding a

workpiece that contains Asbestos or attempting to remove the

Asbestos covering. This requires expert knowledge and equipment.

b. Molten slag can run down the inside and outside of a pipe and start a

fire. Be aware where the pipe terminates and take precautions.

8. Do not weld a panel that is a sandwich construction of combustible and

metal materials.

9. Have a fire extinguisher available for immediate use. A dry chemical fire

extinguisher for Types A, B and C is suggested.

a. Welding a combustible metal like zinc, magnesium or titanium

requires a Type D fire extinguisher.

b. Do not use liquid based fire extinguishing methods near the electric

arc welding unit, as it may cause a shock hazard.

10. Ventilation systems should be positioned so sparks or molten slag isn’t

carried to an adjacent area.

11. Have a Fire Watcher observing areas outside of the welder’s view, such as

the opposite side of a wall or behind the welder. A fire may also start on the

other side of a structure that could not be removed. The Fire Watcher will

extinguish a fire or raise the alarm to evacuate if the fire cannot be

contained by the extinguishing equipment.

a. A fire watch extends at least 30 minutes after the welding is complete

to ensure there are no fires caused by smoldering sparks or ejected

material.

FUMES AND GASES

WARNING! Stop welding and move to a location with ventilation if your eyes,

nose or throat become irritated. This indicates the ventilation is not

adequate to remove the fumes. Do not resume welding until the ventilation

is improved and the discomfort ceases. Seek medical attention if the

symptoms do not diminish or if the welder experiences nausea, dizziness

or malaise.

Welding may produce hazardous fumes and gas during the welding process. A well

ventilated work area can normally remove the fumes and gases, but sometimes the

welding produces fumes and gases that are hazardous to your health.

1. Only work in a confined space if the area is well ventilated or while wearing

a respirator or an air-supplied respirator. Welding fumes and gases can

displace air and lower the oxygen level causing injury or death. Be sure the

breathing air is safe. Always have a trained watchperson nearby.

a. If ventilation in the work area is poor, use an approved air-supplied

respirator. All the people in the work area must also have air-supplied

respirators.

b. Oxygen displacement can occur in confined areas when the shielding

gas fills the area and pushes out air.

2. Avoid positions that allow welding fumes to reach your face. Always attempt to

weld ‘upwind’ of the workpiece with the airflow across the face of the welder.

Airflow from behind may create a low pressure area in front of the welder and

draw the fumes to the person.

3. Ventilate the work area to remove welding fumes and gases. The fumes

and gases should be drawn away from the user.

a. Ventilation should be enough to disperse fumes, but not enough to

disturb the shielding gas or flame during welding.

b. Ventilation exhaust shall be directed to a non-work area to avoid

exposing other people to potential toxic or dangerous fumes.

c. Air removed from the work area by the ventilation system must be

replenished with fresh air to avoid oxygen starvation or a build-up of fumes

or gases. Only use air to provide ventilation. Any other combination of

gases may be explosive or toxic to people in the work area.

8785115 200A Multi-Process Welder with LCD Display V4.0

12 For technical questions call 1-800-665-8685

d. Ventilation methods that remove gas and fumes from the welding

point before they reach the welder’s face should be given preference.

4. Avoid welding in a work area that has vapours from cleaning, degreasing or

any spraying operations. The heat and light from welding can react with the

vapour and form irritating or potentially toxic gases. Wait for the vapours to

disperse.

5. Consult the manufacturer's Safety Data Sheets (SDS) for instructions and

precautions about metals, consumables, coatings, cleaners and degreasers.

a. Do not weld on coated metals such as galvanized, lead or cadmium

plated steel, unless the coating is removed from the weld area. The

coatings and any metals containing these elements can give off toxic

fumes during the welding process.

b. Do not weld, cut or heat lead, zinc, cadmium, mercury, beryllium or

similar metals without seeking professional advice and inspection of the

welding area’s ventilation. These metals produce extreme toxic fumes,

which can cause discomfort, illness and death.

c. Do not weld or cut near chlorinated solvents or in areas that

chlorinates solvents can enter. The heat or ultraviolet light of the arc

can separate chlorinated hydrocarbons into a toxic gas (phosgene)

that can poison or suffocate the user or bystanders.

6. Check the Safety Data Sheet for the proper handling and safety precautions

for consumable welding rods as the coating can have multiple chemicals.

COMPRESSED GAS CYLINDER PRECAUTIONS

WARNING! Improper handling or maintenance of compressed gas cylinders

and regulators can result in serious injury or death. Do not use a cylinder or

its contents for anything other than its intended use.

1. Only use inert or nonflammable gas with the welding unit such as Carbon

Dioxide, Argon or Helium with the welding unit.

a. Never use flammable gases. They will ignite and may result in an explosion

or fire that can cause death or injury.

2. Do not attempt to mix gases or refill a gas cylinder. Exchange a cylinder or

have it refilled by a professional service.

V4.0 200A Multi-Process Welder with LCD Display 8785115

Visit www.princessauto.com for more information 13

3. Do not deface or alter the name, number or other markings on a cylinder. Do not

rely on a cylinder’s colour to identify the contents. Do not connect a regulator to

a cylinder that contains a gas that the regulator was not designed to handle.

4. Do not expose a cylinder to excessive heat, sparks, slag, flame or any other

heat source.

a. A cylinder exposed to temperatures above 130 °F will require water

spray cooling. This method may not be compatible with electric

welding units due to the hazard of electrocution.

5. Do not expose a cylinder to electricity of any kind.

6. Do not attempt to lubricate a regulator. Always change a cylinder carefully

to prevent leaks and damage to the cylinder’s walls, valve or safety

devices.

7. Gases in the cylinder are under pressure. Protect the cylinder from bumps,

falls, falling objects and harsh weather. A punctured cylinder under

pressure can become a lethal projectile. If a cylinder is punctured, do not

approach until all pressure is released.

a. Protect the valve and regulator. Damage to either can result in

regulator’s explosive ejection from the cylinder.

8. Always secure a gas cylinder in a vertical position to a welding cart or

other fixed support with a steel chain, so it cannot be knocked over.

a. Away from areas where they may be struck or subjected to physical

damage.

b. A safe distance from arc welding or cutting operations and any other

source of heat, sparks or flame.

b. Do not use as an improvised support or roller.

9. Always place the cylinder cap securely on the cylinder unless it is in use or

being serviced.

10. Do not use a wrench or hammer to open a cylinder valve that cannot be

opened by hand. Notify your supplier for instructions.

11. Do not modify or exchange gas cylinder fittings.

12. Close the cylinder valve and immediately remove the faulty regulator from

service for repair, if any of the following conditions exist:

8785115 200A Multi-Process Welder with LCD Display V4.0

14 For technical questions call 1-800-665-8685

a. Gas leaks externally.

b. Delivery pressure continues to rise with the downstream valve

closed.

c. The gauge pointer does not move off the stop pin when pressurized

or fails to return to the stop pin after pressure is released.

13. Do not attempt to make regulator repairs. Send faulty regulators to the

manufacturer's designated repair center.

14. Do not weld on the gas cylinder.

15. Keep your head and face away from the cylinder valve outlet when opening the

cylinder valve.

16. Compressed gas cylinders must not be located in a confined space with the

person welding to prevent the possibility of leaks displacing the oxygen.

ELECTRICAL SAFETY

1. Do not come into physical contact with the welding current circuit. The

welding current circuit includes:

a. The workpiece or any conductive material in contact with it.

b. The ground clamp.

c. The electrode or welding wire;

d. Any metal parts on the electrode holder or wire feed torch.

e. The output terminals.

2. Insulate yourself from the electrical current and ground using electrical

insulating mats or covers big enough to prevent physical contact with the

workpiece or ground.

3. Connect the ground clamp as close to the welding area on the workpiece

as practical to prevent welding current from traveling along an unexpected

path and causing an electric shock or fire hazard.

a. An option is to attach the ground clamp to a bare metal spot on a

metal workbench. The circuit will complete as long as the workpiece

is also in full contact with the bare metal workbench.

4. Only use insulated connectors to join welding cables.

5. Ensure there are no contacts between the workpiece and work area that

would allow it to ground, other than through the ground cable circuit

V4.0 200A Multi-Process Welder with LCD Display 8785115

Visit www.princessauto.com for more information 15

6. Do not exceed the duty cycle or amperage required for the type of welding.

Excessive amperage can cause the deterioration of protective insulation

and create a shock hazard.

7. Unplug the welding unit when not in use as the unit as current is still

entering the unit, even when it is turned off.

8. Frequently inspect input power cable for wear and tear, replace the cable

immediately if damaged. Bare wiring is dangerous and can kill.

9. Do not use damaged, under sized or badly joined cables.

10. Do not disconnect the power cord in place of using the ON/OFF switch on

the tool. This will prevent an accidental startup when the power cord is

plugged into the power supply.

a. In the event of a power failure, turn off the machine as soon as the

power is interrupted. The possibility of accidental injury could occur, if

the power returns and the unit is not switched off.

11. Make certain the power source conforms to requirements of your

equipment (see Specifications).

POWER TOOL PRECAUTIONS

This equipment requires a dedicated 120/230 VAC, 15 amp single-phase

alternating current circuit equipped with a similarly rated circuit breaker or slow

blow fuse. Do not run other appliances, lights, tools or equipment on the circuit

while operating this welding unit.

1. Do not drape or carry coiled welding cables on your body while the cables

are plugged into the welding unit.

2. Do not start the tool when the electrode is touching the workpiece.

3. Hold the tool by the insulated gripping surfaces when performing an

operation where it may contact hidden wiring or its own cord and cables.

Contact with a ‘live’ wire will electrify exposed metal parts and shock the

operator.

4. Take work breaks to prevent the tool's motor from overheating and/or

overloading. Refer to the welding unit’s duty cycle in Specifications.

5. Keep hands away from the electrode and the area it is being applied to

when the tool is in operation.

8785115 200A Multi-Process Welder with LCD Display V4.0

6. Do not connect the welding unit ground clamp to an electrical conduit. Do

not weld on an electrical conduit.

7. Do not touch the electrode or welded surface immediately after use. The

surface will be hot and may cause an injury.

8. Never use a tool with a cracked or worn electrode. Change the electrode

before using and discard the damaged one.

POWER CORD

1. Insert the power cord plug directly to the power supply whenever possible.

Extension cords are not recommended for use with this welding unit.

a. When an extension cord is required, use a welding version that

exceeds the welding unit’s maximum power requirement.

2. Do not operate this tool if the power cord is frayed or damaged, as an electric

shock or surge may occur, resulting in personal injury or property damage.

a. Inspect the tool's power cord for cracks, fraying or other faults in the

insulation or plug before each use.

b. Discontinue use if a power cord feels more than comfortably warm

while operating the tool.

3. Keep all connections dry and off the ground to reduce the risk of electric

shock. Do not touch plug with wet hands.

4. Prevent damage to the power cord by observing the following:

a. Do not pull on the cord to disconnect the plug from an outlet.

b. Keep cord away from heat, oil, sharp edges or moving parts.

c. Place the electrical cord in a position that prevents it from contacting the

tool or workpiece. The cord should always stay behind the tool.

5. Make sure to locate the cord so that it is not stepped on, tripped over or

otherwise subject to damage or stress.

6. Do not wrap the cord around the tool, as sharp edges may cut insulation or

cause cracks if wound too tight. Gently coil cord and either hang on a hook

or fasten with a device to keep cord together during storage.

ELECTROMAGNETIC FIELDS

WARNING! Stop welding immediately and move away from the welding unit if

you feel faint, dizzy, nausea or shocks. Seek medical attention.

Electromagnetic Fields (EMF) can interfere with electronic devices such as

pacemakers. Anyone with a pacemaker should consult with their doctor before

working with or near an arc welding unit. The following steps can minimize the

effects of electromagnetic fields.

1. Twist or tape cables together and prevent coils.

2. Do not drape cables on your body.

3. Keep the welding power source and cables as far away from the user as

practical. A minimum of 24 in. is recommended.

4. Connect the workpiece clamp as close to the weld as possible, but lay the

electrode and workpiece cables away from the user.

5. Use the lowest current setting possible during welding.

6. Avoid long and regular bursts of energy while welding. Apply the electrode

in short strokes and intermittently. This will prevent the pacemaker from

interpreting the signal as a rapid heartbeat.

7. Do not allow the electrode to touch the metal while welding.

8. Keep the lead cable and ground cables on the same side of your body.

9. Do not weld while carrying the welding power source.

10. Do not work next to, sit or lean on the welding power source.
