free of distractions.
2. Remove all unnecessary people from the work area when welding.
Anyone remaining in the work area must wear the appropriate welding
safety equipment.
3. Store tools properly in a safe and dry location. Keep tools out of the reach
of children.
4. Do not weld on damp surfaces that can transmit the electric current
without taking precautions for the welder and bystanders. The electrode,
welding head and nozzle are electrically ‘hot’.
5. Do not install or use in the presence of flammable gases, dust or liquids.
6. Welding sparks and ejected molten slag can start a fire. Remove
combustible materials within 39 ft (12 metres) of the welding unit. See Fire
and Explosion Precautions.
7. Have a fire extinguisher readily available (see Fire and Explosion
Precautions).
8. Use protective screens or barriers to protect others from flash and glare;
warn others in the area to look away from the arc.
9. Keep the welding unit at least one foot from any wall or structure.
10. Check that the work area is free from fires, sparks or hot debris
before leaving.
PERSONAL SAFETY
WARNING! Wear personal protective equipment approved by the Canadian
Standards Association (CSA) or American National Standards Institute (ANSI).
HEAD PROTECTION
DANGER! Never look directly at the welding arc without the proper
protection. The light can cause flash burn damage and impair vision.
Although treatment is possible, multiple occurrences can result in
permanent eye damage.
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.
V1.1 Multi-Process Welder 9038787
Visit www.princessauto.com for more information 5
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.
2. Avoid wearing clothes or jewelry that can become entangled with the
moving parts of a tool. Keep long hair covered or bound.
3. Remove all jewelry or metal items from your person before welding. Metal
items may connect to the welding unit’s electrical circuit, causing an injury
or death.
4. Do not overreach when operating the tool. Proper footing and balance enables
better control in unexpected situations.
5. Support the workpiece or clamp it to a stable platform. Holding the
workpiece by hand or against your body may lead to personal injury.
6. Do not wear any personal grooming products that are flammable, such as
hair preparations, perfume or cologne with an alcohol base.

these can cause direct harm to the eyes and skin of the welder or bystanders.
1. Use the correct tool for the job. This tool was designed for a
specific function. Do not modify or alter this tool or use it f
o
r
an unintended purpose.
2. Arc welding requires the use a hand-held face shield or helmets with full
face protection per CSA standard Z94.3.1.
3. Protect against reflected arc rays. The rays can reflect off a shiny surfaces
behind the user, into the helmet and off the filter lens into the eyes.
Remove or cover any reflective surface behind the user such as a glossy
painted surface, aluminum, stainless steel or glass.
4. Welding produces sparks and molten slag. A cooling bead can eject chips
or fragments of slag. Any of these can cause direct harm to the eyes or
skin of the user or bystanders.
5. Erect protective screens or barriers to protect bystanders from the flash
and glare; warn others in the area not to watch the arc. Do not strike a
welding arc until all bystanders and you (the user) have welding shields
and/or helmets in place.
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.
9038787 Multi-Process Welder V1.1
8 For technical questions call 1-800-665-8685
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.
V1.1 Multi-Process Welder 9038787
Visit www.princessauto.com for more information 9
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.
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.
9038787 Multi-Process Welder V1.1
10 For technical questions call 1-800-665-8685
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.
V1.1 Multi-Process Welder 9038787
Visit www.princessauto.com for more information 11
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.
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.
9038787 Multi-Process Welder V1.1
12 For technical questions call 1-800-665-8685
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.
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.
V1.1 Multi-Process Welder 9038787
Visit www.princessauto.com for more information 13
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:
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.
9038787 Multi-Process Welder V1.1
14 For technical questions call 1-800-665-8685
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
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.

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.

The multi-functions screen displays nine welding
options plus the interface settings option. The
selected option and the title indicates the type of
welding and workpiece material.
OUTPUT SET-UP
Selecting the welding option will open the output set-
up screen. This displays the welding unit configuration.
In Fig. 4 the dinse connector (D) is plugged into the
positive output for stick welding. The ground cable
would plug into the other polarity outlet.
ELECTRODE OR WIRE SIZE
The welding machine uses either an electrode or
welding wire to create the arc.
The electrode screen offers two choices of electrode
type 60xx or 70xx base.
The wire size screen offers different wire size
choices based on the material selected.
Select the size that is appropriate for your welding task.
MATERIAL THICKNESS
The thickness screen displays the different
thicknesses of the workpiece in mm. Turn the multi-
function adjustment knob (P3) for the correct
thickness, then push the knob in to select it.
WELDING DISPLAY
Once the type of welding and material thickness is set, you can make final
adjustments to the welding parameters. Parameters already set or that are pre-
determined are displayed on the screen.
Adjustable settings may be selected by rotating the multi-function adjustment
knob (P3) to progress through each. The setting is highlighted in orange. Press
the knob to select the setting. This may bring up a new screen with additional
options or allow you to adjust the setting if there is no other option.

Rotate the multi-function knob to adjust the setting. Some settings will display
an orange bar. This bar displays the available range for the setting. A green
section in the bar indicates the recommended range for the best results based
on the other options selected.
The voltage is changed turning the auxiliary knob (P7).
Return to a previous setting or screen by pressing the return key (P6). Press
the home key (P5) to return to the start screen.
Each type of welding will have different set-up options.
MIG Parameters already set such as welding type,
gas type and mix and the welding wire diameter are
displayed in the screen’s middle section.
Material thickness, wire speed and voltage are
displayed on the upper screen. The wire speed and
voltage may be adjusted.
Additional options are available:
Set Torch Operation 2T / 4T (Fig. 9-1)
.
2T
Press and hold the trigger to start the arc.
Release the trigger to stop.
4T
Press and release the trigger to start the arc.
Press and release the trigger to stop the arc.
Gas Pre-Flow (Fig. 9-2)
Choose the
length of time the shield gas begins
to flow before the arc ignites.
Slow Wire Feed (Fig. 9-3) –
The
welding unit has a feed-on-demand
system to prevent wire waste.
Initially the wire is slowly fed through the torch, regardless of the set speed.
Once an arc is struck, the unit feeds the wire at the user’s selected speed.
Burnback Setting (Fig. 9-4)Burnback is a feature that continues to supply
power to the welding wire after the torch trigger is release, but stops the
welding wire from feeding. This provides time for the welder to remove the
welding wire from the weld pool before it solidifies. The setting is preset by
the factory.

Gas Post-Flow (Fig. 9-5)
Choose the length of time the gas flows after the arc
is extinguished to prevent weld contamination.
Load and Save (Fig. 9-6 and 9-7)
The MIG settings may be saved into the
memory and then reloaded for future welding tasks.
TIG The current parameter is adjustable.
There is no foot pedal option with this welder.
STICK (ARC) The current, arc force and
hot start parameters are adjustable. VRD is
ON or OFF.
ARC Force (Fig. 11-1)
Welding in difficult areas
or angles may require a longer arc length,
creating a voltage drop. The ARC Force
increases the amperage to compensate for the
lost power and maintain the heat of the weld.
Hot Start (Fig. 11-2) –
The current increases
temporarily during arc ignition to make sure a
reliable arc is quickly established.
Voltage Reduction Device (VRD) (Fig. 11-3)
Select to turn VRD ON or OFF. VRD reduces the voltage at the welding torch or
electrode when there is no load.
WARNING! VRD does not shut the voltage off. The welding torch or
electrode is still live and can inflict an electrical or burn injury if touched.
THERMAL OVERLOAD PROTECTION
Constantly exceeding the duty cycle can damage
the welding unit. An internal thermal protector will
open when the welding unit is too hot, shutting
OFF all functions except the cooling fan. Leave the
welding unit turned on with the fan running. The
thermal protector will automatically reset and the
welding unit will function normally again once it
has cooled.
