GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS.Failure to follow all instructions
listed below may result in electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
Work Area
1. Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence
of flammable liquids, gases, or dust. Power tools create sparks which may ignite
the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a power tool.

For technical questions, please call 1-800-444-3353;
Troubleshooting section at end of manual. Page 4SKU 55167
Distractions can cause you to lose control. Protect others in the work area from debris
such as chips and sparks. Provide barriers or shields as needed.
Electrical Safety
4. Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and
refrigerators. There is an increased risk of electric shock if your body is grounded.
5. Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
6. Grounded tools must be plugged into an outlet properly installed and grounded in
accordance with all codes and ordinances. Never remove the grounding prong or
modify the plug in any way. Do not use any adapter plugs. Check with a qualified
electrician if you are in doubt as to whether the outlet is properly grounded. If the
tools should electrically malfunction or break down, grounding provides a low resistance
path to carry electricity away from the user.
7. Do not abuse the Power Cord. Never use the Power Cord to carry the tools or pull
the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp edges,
or moving parts. Replace damaged Power Cords immediately. Damaged Power
Cords increase the risk of electric shock.
8. When operating a power tool outside, use an outdoor extension cord marked
“W-A” or “W”. These extension cords are rated for outdoor use, and reduce the risk
of electric shock.
Personal Safety
9. Stay alert. Watch what you are doing, and use common sense when operating a
power tool. Do not use a power tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating power tools may
result in serious personal injury.
10. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from arc. Loose clothes, jewelry, or long hair
can catch fire.
11. Avoid accidental starting. Be sure the Power Switch is off before plugging in.
Carrying power tools with your finger on the Power Switch, or plugging in power tools
with the Power Switch on, invites accidents.
12. Remove adjusting keys or wrenches before turning the power tool on. A wrench
or a key that is left attached to a rotating part of the power tool may result in personal
injury.
13. Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
14. Use safety equipment. Always wear eye protection. For welding safety equipment,
refer to number 7 on page 6.
Tool Use and Care

For technical questions, please call 1-800-444-3353;
Troubleshooting section at end of manual. Page 5SKU 55167
15. Use clamps (not included) or other practical ways to secure and support the
workpiece to a stable platform. Holding the work by hand or against your body is
unstable and may lead to loss of control.
16. Do not force the tool. Use the correct tool for your application. The correct tool
will do the job better and safer at the rate for which it is designed.
17. Do not use the power tool if the Power Switch does not turn it on or off. Any tool
that cannot be controlled with the Power Switch is dangerous and must be replaced.
18. Unless explicitly instructed otherwise, disconnect the Power Cord Plug from
the power source before making any adjustments, changing accessories, or
storing the tool. Such preventive safety measures reduce the risk of starting the tool
accidentally.
19. Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
20. Maintain tools with care. Keep tools in good repair. Properly maintained tools will
get the job done better. Do not use a damaged tool. Tag damaged tools “Do not use”
until repaired.
21. Check for breakage of parts, and any other condition that may affect the tool’s
operation. If damaged, have the tool serviced before using. Many accidents are
caused by poorly maintained tools.
22. Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may become hazardous when used on
another tool.
Service
23. Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
24. When servicing a tool, use only identical replacement parts. Follow instructions
in the “Inspection, Maintenance, And Cleaning” section of this manual. Use of
unauthorized parts or failure to follow maintenance instructions may create a risk of
electric shock or injury.
SPECIFIC SAFETY RULES

If unreadable or missing, contact Harbor Freight Tools for a replacement.
2. Maintain a safe working environment. Keep the work area well lit. Make sure there
is adequate surrounding workspace. Always keep the work area free of obstructions,
grease, oil, trash, and other debris. Do not use a power tool in areas near flammable
chemicals, dusts, and vapors. Do not use this product in a damp or wet location.
3. Avoid unintentional starting. Make sure you are prepared to begin work before
turning on the Welder.

For technical questions, please call 1-800-444-3353;
Troubleshooting section at end of manual. Page 6SKU 55167
4. Unplug before performing maintenance. Always unplug the Welder from its electrical
outlet before performing any inspection, maintenance, or cleaning procedures.
5. Never leave the Welder unattended while energized. Turn power off if you have to
leave the Welder.
6. Maintain a safe working environment. Keep the work area well lit. Make sure there
is adequate surrounding workspace. Always keep the work area free of obstructions,
grease, oil, trash, and other debris.
7. Prevent eye injury and burns. Wearing and using ANSI-approved personal
safety clothing and safety devices reduce the risk for injury.
• Wear ANSI-approved safety impact eye goggles underneath welding eye
protection featuring at least a number 10 shade lens rating, such as the one
included.
• Leather leggings, fire resistant shoes or boots should be worn when using this product.
Do not wear pants with cuffs, shirts with open pockets, or any clothing that can catch
and hold molten metal or sparks.
• Keep clothing free of grease, oil, solvents, or any flammable substances. Wear dry,
insulating gloves and protective clothing.
• Wear an approved head covering to protect the head and neck. Use aprons, cape,
sleeves, shoulder covers, and bibs designed and approved for welding and cutting
procedures.
• When welding/cutting overhead or in confined spaces, wear flame resistant ear plugs
or ear muffs to keep sparks out of ears.
8. Prevent accidental fires. Remove any combustible material from the work area.
• When possible, move the work to a location well away from combustible
materials. If relocation is not possible, protect the combustibles with a cover
made of fire resistant material.
• Remove or make safe all combustible materials for a radius of 35 feet (10 meters)
around the work area. Use a fire resistant material to cover or block all open doorways,
windows, cracks, and other openings.
• Enclose the work area with portable fire resistant screens. Protect combustible walls,
ceilings, floors, etc., from sparks and heat with fire resistant covers.
• If working on a metal wall, ceiling, etc., prevent ignition of combustibles on the other
side by moving the combustibles to a safe location. If relocation of combustibles is
not possible, designate someone to serve as a fire watch, equipped with a fire extin-
guisher, during the cutting process and for at least one half hour after the cutting is
completed.
• Do not weld or cut on materials having a combustible coating or combustible internal
structure, as in walls or ceilings, without an approved method for eliminating the haz-
ard.
• Do not dispose of hot slag in containers holding combustible materials. Keep a fire
extinguisher nearby and know how to use it.
• After spot welding, make a thorough examination for evidence of fire. Be aware that

For technical questions, please call 1-800-444-3353;
Troubleshooting section at end of manual. Page 7SKU 55167
easily visible smoke or flame may not be present for some time after the fire has
started. Do not weld or cut in atmospheres containing dangerously reactive or flam-
mable gases, vapors, liquids, and dust. Provide adequate ventilation in work areas
to prevent accumulation of flammable gases, vapors, and dust. Do not apply heat to
a container that has held an unknown substance or a combustible material whose
contents, when heated, can produce flammable or explosive vapors. Clean and purge
containers before applying heat. Vent closed containers, including castings, before
preheating, welding, or cutting.
9. Avoid overexposure to fumes and gases. Always keep your head out of the fumes.
Do not breathe the fumes. Use enough ventilation or exhaust, or both, to keep fumes
and gases from your breathing zone and general area.
• Where ventilation is questionable, have a qualified technician take an air sampling to
determine the need for corrective measures. Use mechanical ventilation to improve
air quality. If engineering controls are not feasible, use an approved respirator.
• Work in a confined area only if it is well-ventilated, or while wearing an air-supplied
respirator.
• Follow OSHA guidelines for Permissible Exposure Limits (PEL’s) for various fumes
and gases.
• Follow the American Conference of Governmental Industrial Hygienists recommenda-
tions for Threshold Limit Values (TLV’s) for fumes and gases.
• Have a recognized specialist in Industrial Hygiene or Environmental Services check
the operation and air quality and make recommendations for the specific welding or
cutting situation.
10.
Inhalation Hazard
Welding Produces TOXIC FUMES and GASSES.
Exposure to welding gasses can increase the risk of developing
certain cancers, such as cancer of the larynx and lung cancer.
Also, some diseases that may be linked to exposure to welding gasses
or fumes are:
• Early onset of Parkinson’s Disease • Heart Disease
• Damage to the reproductive organs • Ulcers
• Inflammation of the small intestine or stomach • Kidney damage
• Respiratory diseases such as emphysema, bronchitis or pneumonia
Safety precautions, such as using natural or forced air ventilation and
wearing an ANSI-approved respirator, are ESSENTIAL to reduce the risk
of developing the above illnesses.
Read and understand all instructions and safety precautions as outlined in the
manufacturer’s manual for the material you will weld or cut.
11. Do not touch live electrical parts.Wear dry, insulating gloves. Do not touch electrode
or conductor tong with bare hand. Do not wear wet or damaged gloves.

For technical questions, please call 1-800-444-3353;
Troubleshooting section at end of manual. Page 8SKU 55167
12. Protect yourself from electric shock. Do not use outdoors. Insulate yourself from
the workpiece and ground. Use nonflammable, dry insulating material if possible, or
use dry rubber mats, dry wood or plywood, or other dry insulating material big enough
to cover your full area of contact with the work or ground.
13. WARNING! People with pacemakers should consult their physician(s) before
using this product. Electromagnetic fields in close proximity to a heart pacemaker
could cause interference to, or failure of the pacemaker.
14. Use care not to touch the welding tip to grounded material whenever the unit is
plugged in. This unit is what is referred to as a “hot tip” welder, meaning that
current is available to the wire at all times that the power Switch (7a) is in the ON
position. Electric shock, fire, or burns may happen if appropriate precautions are not
taken.
15. Ensure that the unit is placed on a stable location before use. If this unit falls while
plugged in, severe injury, electric shock, or fire may result.
16. WARNING! This product, when used for welding and similar applications, contains or
produces a chemical known to the State of California to cause cancer and birth defects
(or other reproductive harm). (California Health & Safety Code § 25249.5, et seq.)
GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the power cord plug provided with the tool.
Never remove the grounding prong from the plug. Do not use the tool if the
power cord or plug is damaged. If damaged, have it repaired by a service facil-
ity before use. If the plug will not fit the outlet, have a proper outlet installed by
a qualified electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
Tools marked with “Grounding Required” have a three wire cord and three prong ground-
ing plug. The plug must be connected to a properly grounded outlet. If the tool should
electrically malfunction or break down, grounding provides a low resistance path to
carry electricity away from the user, reducing the risk of electric shock. (See 3-Prong
Plug and Outlet.)
The grounding prong in the plug is connected through the green wire inside the cord
to the grounding system in the tool. The green wire in the cord must be the only wire
connected to the tool’s grounding system and must never be attached to an electrically
“live” terminal. (See 3-Prong Plug and Outlet.)
1.
2.

For technical questions, please call 1-800-444-3353;
Troubleshooting section at end of manual. Page 9SKU 55167
Your tool must be plugged into an appropriate outlet, properly installed and grounded in
accordance with all codes and ordinances. The plug and outlet should look like those
in the following illustration. (See 3-Prong Plug and Outlet.)
3-Prong Plug and Outlet Outlets for 2-Prong Plug
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
Tools marked “Double Insulated” do not require grounding. They have a special double
insulation system which satisfies OSHA requirements and complies with the applicable
standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and
the National Electrical Code. (See Outlets for 2-Prong Plug.)
Double insulated tools may be used in either of the 120 volt outlets shown in the pre-
ceding illustration. (See Outlets for 2-Prong Plug.)
EXTENSION CORDS
1. Grounded tools require a three wire extension cord. Double Insulated tools can use
either a two or three wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a serious
drop in voltage, resulting in loss of power and possible tool damage.
(See Figure C, next page.)
3. The smaller the gauge number of the wire, the greater the capacity of the cord. For
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Figure C.)
4. When using more than one extension cord to make up the total length, make sure each
cord contains at least the minimum wire size required. (See Figure C.)
5. If you are using one extension cord for more than one tool, add the nameplate amperes
and use the sum to determine the required minimum cord size. (See Figure C.)
6. If you are using an extension cord outdoors, make sure it is marked with the suffix “W-
A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7. Make sure your extension cord is properly wired and in good electrical condition. Always
replace a damaged extension cord or have it repaired by a qualified electrician before
using it.
8. Protect your extension cords from sharp objects, excessive heat, and damp or wet

OPERATION
BEFORE YOU START WELDING
Good welding takes a degree of skill and experience. You should practice a few sample
welds on scrap before you start welding your first project. Additional practice periods are
recommended whenever you weld a different thickness of material or weld a different type of
connection.
DUTY CYCLE (DURATION OF USE)
Avoid damage to the Welder by not leaving it on for more than the prescribed
duty cycle time. The Duty Cycle defines the number of minutes, within a 10 minute period,
during which a given welder can safely produce a particular welding current. For example, this
Welder with a 10% duty cycle at 80 amps must be allowed to rest for at least 9 minutes after
every minute of continuous weld at 80 amps. Failure to carefully observe duty cycle limitations
can easily over stress a welder’s power generation system contributing to premature welder
failure. This welder has an internal thermal protection system to assist with preventing this
sort of over stress. When the unit overheats, it automatically shuts down, then automatically
returns to service when it cools down. When it returns to service, follow a more conservative
duty cycle routine to help prevent excess wear to the welder.

Ground Cable (33) Power Cord (32)
Warning: Before arc welding, read and understand all safety precautions and warnings
listed on pages 3 through 10.
1. Securely clamp the Ground Cable Clamp (33) as close as possible to the metal object
to be welded, or to the metal work bench where the object is mounted and electrically
connected.
2. Set the Current Switch (7b) to the desired current setting. Refer to the chart on the
face of the welder or the chart on page 18 of this manual.
DO NOT SWITCH THE CURRENT WHILE WELDING.
3. Verify that the Power Switch is in the OFF position, then plug the Flux Wire Welder
plug into a dedicated, 110 VAC, 20 amp line with delayed action type circuit breaker or
fuses.
If an extension cord is used, it must have the following wire size: up to 30 feet, use 10
AWG size wire; 30 to 50 feet, use 8 AWG wire; Over 50 feet, use 6 AWG wire.
4. The workpieces should be firmly held together and in position while welding. Use
clamps (not included) to hold the workpieces so that you can concentrate on the job at
hand. The distance (if any) between the two workpieces must be controlled properly
to allow the weld to hold both sides securely while allowing the weld to penetrate fully
into the joint.
5. While holding the Torch with the wire and tip clearly out of the way of any grounded

objects, turn the Power Switch to the ON position.
6. Orient yourself on the area to be welded, then place the Face Shield over your eyes.
Warning: Never look at the ignited arc without ANSI approved, arc shaded, eye protec-
tion in a full face shield. Permanent eye damage or blindness can occur. Skin burns
can occur. Never breathe arc fumes.
HOLDING THE TORCH
7. Hold the Torch (1) in one hand and the face shield in the other.
If a hands-free welding shield (not included, see #7, page 6 for
guidelines) is used, then both hands can be used to control the
Torch. The welding wire should be directed straight into the joint.
This gives an angle of 90° (straight up and down) for groove
(end to end) welds, and an angle of 45° for fillet (T-shaped)
welds. The end of the gun should be tilted so that the wire is
angled anywhere in-between straight on and 15° in the direction
of the weld. The amount of tilt is called the drag angle - see
illustration, right. The welding wire should extend no more than
1/2” past the tip (this distance is called stickout).
8. Set the Wire Feed Control Knob (9) to the recommended start setting as shown in the
chart on the next page. Press (and hold) the Trigger Switch (1c) and stroke the area
to be welded with the electrode wire to ignite the arc.
Never tap the electrode wire into the welding surface to ignite the arc. This will cause
the welding wire to stick to the workpiece.
For a narrow weld, you can usually draw the wire in a steady straight line, this is called
a stringer bead.
For a wider weld, draw the wire back and forth across the joint in a curve, this is called
a weave bead.
Note: If too much current is drawn from the Flux Wire Welder, the Thermal Overload protector
will activate, the amber indicator will light, and the Arc Welder will turn off until it cools down.
If this happens, turn the Power Switch to the OFF position and wait about 3 ~ 5 minutes.
9. After a few seconds, stop, switch off the welder, and check the progress. Compare
your weld’s appearance with the diagrams and descriptions in the Weld Diagnosis
section starting on page 19. After making any necessary adjustments, continue the
weld while carefully following the DUTY CYCLE guidelines as explained on page
15.

WELD DIAGNOSIS
EXCESS OR BURN-THROUGH
Weld droops on top and
underneath, or falls through
entirely, making a hole.
PROPER
Weld is visible underneath and
bulges slightly on top.
INADEQUATE
Weld does not contact the joint
fully, just on the surface.
WELD PENETRATION
POSSIBLE CAUSES AND SOLUTIONS
1. Excessive material at weld:
Reduce wire feed speed.
2. Overheating:
Increase welding speed and ensure that
welding speed is kept steady.
POSSIBLE CAUSES AND SOLUTIONS
1. Workpieces too thick/close:
Joint design must allow weld to reach bot-
tom of groove and allow proper welding
procedures.
2. Incorrect welding technique:
Maintain 1/2” or less stickout.
Keep arc on leading edge of weld pud-
dle.
Hold gun at proper angles as stated under
Holding The Torch on page 17.
3. Insufficient weld material:
Increase wire feed speed.
4. Insufficient weld heat:
Reduce Welding Speed.
CROSS SECTIONS
WELD NOT ADHERING PROPERLY
Gaps present between weld and previous bead or
between weld and workpiece. See areas below.
POSSIBLE CAUSES AND SOLUTIONS
1. Dirty workpiece:
Make certain that workpiece is clean and
free from oil, coatings, and other resi-
dues.
2. Insufficient weld material:
Increase wire feed speed.
3. Incorrect welding technique:
Place stringer bead at correct place in
joint.
Adjust workpiece position or weld angle to
permit proper welding to bottom of piece.
Pause briefly at sides when using a weave
bead.
Keep arc on leading edge of weld
puddle.
Hold gun at proper angles as stated under
Holding The Torch on page 17.
CROSS
SECTION
BEND AT JOINT
POSSIBLE CAUSES AND SOLUTIONS
1. Improper clamping:
Make sure that pieces are clamped se-
curely in place.
Make tack welds to help hold pieces.
2. Excessive heat:
Weld a small portion and allow to cool
before proceeding.
Reduce wire feed speed.
Increase weld speed.

10. When the weld is complete, lift the electrode wire clearly away from any grounded
object, set the Face Shield down, turn toward the Flux Wire Welder, and turn the Power
Switch to the OFF position.
11. Unplug the Power Cord from the electrical outlet. Be sure to set the torch down
on a nonflammable, nonconductive surface.
12. The Wire Brush/Hammer (39) can now be used to clean up the weld.
CAUTION: The weld may still be quite hot and sparks/chips may fly when cleaning.
Be certain to continue to wear ANSI approved safety goggles and protective wear
when cleaning a weld.
The Hammer can be used to knock off any excess spatter and to help knock down any
ridges. Be careful not to damage the weld or material when striking it.
The Wire Brush can then be used to help remove oxidation and some fine spatter.
CROOKED/WAVY BEAD
POSSIBLE CAUSES AND SOLUTIONS
1. Stickout too long:
Reduce stickout.
2. Inaccurate welding:
Use two hands or rest hand on steady
surface.

STRIKE TEST
A test weld on a PIECE OF SCRAP can be tested
by using the following procedure.
WEAR ANSI GOGGLES DURINGTHIS PROCEDURE.
1. After two scraps have been welded to-
gether and the weld has cooled, clamp one
scrap* in a sturdy vise.
2. Stay clear from underneath while you strike
the opposite scrap with a heavy hammer,
preferably a dead-blow hammer.
3. A good weld will deform but not break.
A poor weld will be brittle and snap at the
weld.
*This test WILL damage the weld it is performed
on. This test is ONLY an indicator of weld tech-
nique and is not intended to test working welds.
EXCESSIVE SPATTER
Spatter that is grainy and large.
Fine spatter is normal.
POSSIBLE CAUSES AND SOLUTIONS
1. Wire feeding too fast:
Reduce wire feed speed.
2. Stickout too long:
Reduce stickout.
3. Dirty workpiece or welding wire:
Make certain that workpiece and wire are
both clean and free from oil, coatings, and
other residues.
