FUMES AND GASES can be hazardous to your health.  
1. Exposure to welding or cutting  
4. Use enough ventilation, exhaust at arc, or  
both, to keep fumes and gases from breathing  
zone and general area. If engineering controls  
are not feasible, use an approved respirator.  
exhaust fumes 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 or cutting exhaust fumes are:  
5. Work in a confined area only if it  
is well-ventilated, or while wearing  
an air-supplied respirator.  
• Early onset of Parkinson’s Disease  
• Heart disease  
• Ulcers  
6. Have a recognized specialist in  
Industrial Hygiene or Environmental Services  
check the operation and air quality  
and make recommendations  
• Damage to the reproductive organs  
• Inflammation of the small intestine or  
stomach  
• Kidney damage  
• Respiratory diseases such as  
emphysema, bronchitis, or pneumonia  
for the specific welding situation.  
Follow OSHA guidelines for  
Permissible Exposure Limits (PEL’s) and  
the American Conference of Governmental  
Industrial Hygienists recommendations for  
Threshold Limit Values (TLV’s) for fumes and gases.  
2. Do not use near degreasing or  
painting operations.  
3. Keep head out of fumes.  
Do not breathe exhaust fumes.  
Arc Ray Safety  
ARC RAYS can injure eyes and burn skin.  
1. Wear ANSI-approved welding eye protection  
4. Wear an approved head covering to protect  
the head and neck. Use aprons, cape, sleeves,  
shoulder covers, and bibs designed and  
featuring at least a number 10 shade lens rating.  
2. Wear leather leggings, fire resistant shoes  
or boots during use. Do not wear pants with  
cuffs, shirts with open pockets, or any clothing

the risk of electric shock.  
discharge electrode to ground before setting  
down torch/electrode holder and before service.  
2. Do not touch energized electrical parts.  
Wear dry, insulating gloves. Do not touch electrode  
holder, electrode, welding torch, or welding wire with  
bare hand. Do not wear wet or damaged gloves.  
7. Do not abuse the cord. Never use the cord  
for carrying, pulling or unplugging the welder.  
Keep cord away from heat, oil, sharp edges  
or moving parts. Damaged or entangled  
cords increase the risk of electric shock.  
3. Connect to grounded, GFCI-protected  
power supply only.  
8. Do not use outdoors.  
4. Do not use near water or damp objects.  
9. 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 large enough to cover  
your full area of contact with the work or ground.  
5. People with pacemakers should consult their  
physician(s) before use. Electromagnetic fields  
in close proximity to heart pacemaker could cause  
pacemaker interference or pacemaker failure.  
Fire Safety  
ARC AND HOT SLAG can cause fire.  
1. Clear away or protect flammable objects.  
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.  
5. 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 extinguisher,  
during the cutting process and for at least one  
half hour after the cutting is completed.  
2. Keep ABC-type fire extinguisher near  
work area and know how to use it.  
3. Maintain a safe working environment.  
Keep the work area well lit.  
6. Do not weld or cut on materials having  
a combustible coating or combustible  
Make sure there is adequate surrounding workspace.  
Keep the work area free of obstructions,  
grease, oil, trash, and other debris.

an approved method for eliminating the hazard.  
7. Do not dispose of hot slag in containers  
4. Do not operate welders in atmospheres  
containing dangerously reactive or  
holding combustible materials.  
flammable liquids, gases, vapors, or dust.  
Provide adequate ventilation in work areas  
to prevent accumulation of such substances.  
Welders create sparks which may ignite flammable  
substances or make reactive fumes toxic.  
8. After welding, make a thorough examination  
for evidence of fire. Be aware that easily  
visible smoke or flame may not be present  
for some time after the fire has started.  
9. 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.

Welder use and care  
1. Do not use the welder if the switch does not turn  
it on and off. Any welder that cannot be controlled  
with the switch is dangerous and must be repaired.  
4. Store idle welders out of the reach of children and  
do not allow persons unfamiliar with the welder or  
these instructions to operate the welder. Welders  
are dangerous in the hands of untrained users.  
2. Disconnect the plug from the power  
source before making any adjustments,  
changing accessories, or storing welders.  
Such preventive safety measures reduce the  
risk of starting the welder accidentally.  
5. Use the welder and accessories in accordance  
with these instructions, taking into account the  
working conditions and the work to be performed.  
Use of the welder for operations different from those  
intended could result in a hazardous situation.  
3. Prevent unintentional starting.  
Ensure the switch is in the off-position before  
connecting to power source or moving the welder.  
Carrying or energizing welders that have  
the switch on invites accidents.  
Maintenance  
1. Maintain welders. Check for misalignment or  
binding of moving parts, breakage of parts  
and any other condition that may affect the  
welder’s operation. If damaged, have the  
welder repaired before use. Many accidents  
are caused by poorly maintained welders.  
3. Maintain labels and nameplates on the Welder.  
These carry important information.  
If unreadable or missing, contact  
Harbor Freight Tools for a replacement.  
4. Unplug before maintenance. Unplug the Welder  
from its electrical outlet before any inspection,  
maintenance, or cleaning procedures.  
2. Have your welder serviced by a qualified  
repair person using only identical  
replacement parts. This will ensure that  
the safety of the welder is maintained.  
Gas Shielded Welding - Cylinder safety  
Cylinders can explode when damaged.  
1. Never weld on a pressurized or a closed cylinder.  
5. Use only correct gas shielding equipment  
designed specifically for the type of welding  
you will do. Maintain this equipment properly.  
2. Never allow an electrode holder,  
electrode, welding torch, or welding  
wire to touch the cylinder.  
6. Protect gas cylinders from heat, being struck,  
physical damage, slag, flames, sparks, and arcs.  
3. Keep cylinders away from any electrical circuits,  
including welding circuits.  
7. Always use proper procedures to move cylinders.  
4. Keep protective cap in place over the valve  
except when the cylinder is in use.

Basic Welding  
Read the ENTIRE IMPORTANT SAFETY  
INFORMATION section at the beginning of this  
manual including all text under subheadings  
therein before welding.  
TO PREVENT SERIOUS INJURY:  
Protective gear must be worn when using the  
Welder; minimum shade number 10 full face shield  
(or welding mask), ear protection, welding gloves,  
sleeves and apron, NIOSH-approved respirator, and  
fire resistant work clothes without pockets should be  
worn when welding.  
Light from the arc can cause  
permanent damage to the eyes and skin.  
Do not breathe arc fumes.  
Flux-core wire welding is used to weld sheet metal and  
low carbon steel without shielding gas. MIG welding uses  
solid-core wire and shielding gas, and is used to weld sheet  
metal and low carbon steel. MIG welding can also be used  
to weld thinner workpieces than flux-core welding can.  
Good welding takes a degree of skill and experience.  
Practice a few sample welds on scrap before  
welding your first project. Additional practice  
periods are recommended whenever you weld:  
Practice your welding  
technique on scrap  
pieces before welding  
anything of value.  
a different thickness of material  
a different type of material  
a different type of connection

chart to achieve a good weld.  
Rest the Torch on an electrically non-conductive,  
heat-resistant surface, such as a concrete slab, well  
clear of the ground clamp while allowing the welder  
to cool with the Power Switch on, so the Fan can  
help cool the welder. Once the welder cools enough  
to be used again, use shorter welding periods and  
longer rest periods to prevent needless wear.

Avoid damage to the Welder by not welding  
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 produce a particular welding current  
without overheating. For example, this Welder  
with a 20% duty cycle at rated output (110A)  
must be allowed to rest for at least 8 minutes  
after every 2 minutes of continuous welding.  
Failure to carefully observe any duty cycle limitations  
can easily over-stress a welder’s power generation  
system contributing to premature welder failure.  
20% Rated Duty Cycle  
at 110A output  
2 minutes welding  
followed by  
at least 8 minutes  
of rest  
This welder has an internal thermal protection system  
to help prevent this sort of over-stress. When the unit  
overheats, it automatically shuts down and the Overload  
Indicator lights, then the welder automatically returns  
to service after cooling off. Rest the Torch on an  
Torch  
I
electrically non-conductive, heat-proof surface, such as  
a concrete slab, well clear of the ground clamp while  
allowing the welder to cool with the Power Switch on, so  
that the internal Fan will help cool the welder. When the  
welder can be used again, use shorter welding periods  
and longer rest periods to prevent needless wear.

Setting Up The Weld  
1. Make practice welds on pieces of scrap the  
same thickness as your intended workpiece  
to practice technique before welding anything  
of value. Clean the weld surfaces thoroughly  
with a wire brush or angle grinder; there  
must be no rust, paint, oil, or other materials  
on the weld surfaces, only bare metal.  
2. Use clamps (not included) to hold the workpieces  
in position so that you can concentrate on  
proper welding technique. The distance  
clamps  
workpieces  
(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. The edges of  
thicker workpieces may need to be chamfered  
(or beveled) to allow proper weld penetration.  
Clean  
surfaces to  
bare metal.  
Chamfer thick workpieces.

DANGER! TO PREVENT DEATH  
FROM ASPHYXIATION:  
Do not open gas without proper ventilation. Fix gas  
leaks immediately.  
Shielding gas can displace air and cause rapid loss of  
consciousness and death.  
Shielding gas without carbon dioxide can be even  
more hazardous,  
because asphyxiation can start  
without feeling shortness of breath.

Open gas tank valve and adjust regulator/  
flowmeter to flow rate indicated on chart.

Basic Welding Technique  
1. Press (and hold) Trigger and contact area to  
be welded with electrode wire to ignite arc.  
2. For a narrow weld, you can usually draw the wire in  
a steady straight line,  
stringer bead  
weave bead  
this is called a stringer bead.  
For a wider weld, draw the wire back and forth  
across the joint,  
this is called a weave bead and takes  
practice to perform properly.  
3. Hold Torch in one hand and the face shield in  
the other. If a hands-free welding shield (not  
included, see #6, page 4 for guidelines) is used,  
then both hands can be used to control Torch.  
Weld Torch angles,  
viewed from front of weld joint.  
4. Direct the welding wire straight into the joint.  
This gives an angle of 90° (straight up and  
down) for butt (end to end) welds, and an  
angle of 45° for fillet (T-shaped) welds.  
90°  
butt weld joint  
45°

5. The end of torch should be tilted so that wire  
is angled anywhere in-between straight on  
and 15° in the direction you are welding. The  
amount of tilt is called the drag angle.  
Drag Angle

Note: If Welder is used too long, the amber Overload  
Indicator will light and the Welder Torch will shut off  
until the welder cools. If this happens, rest the Torch  
on an electrically non-conductive, heat-resistant  
surface, such as a concrete slab, well clear of the  
ground clamp. Wait about 8-10 minutes with the Power  
Switch ON for the welder to cool. When the welder  
can be used again, use shorter welding periods and  
longer rest periods to help prevent needless wear.

Welding Tips  
A typical flux-core wire (FCAW) weld  
before cleaning.  
A good way to test welding technique is to examine  
a weld’s appearance after it has cooled and the slag  
has been removed. Then, better welding can be  
learned by adjusting your weld technique  
to remedy any problems found.

Verify the voltage at the outlet and the connection to the outlet.  
If voltage is not present at outlet, check circuit breaker/GFCI devices; if any are tripped, determine and remedy  
cause before resetting.  
Verify that the circuit is designed to supply the required input voltage and amperage as detailed on the  
Specifications table.  
Make sure installed plug is correct rating (250 V~, 50 A recommended) - see page 7.  
Wire Feeds, but arc does not ignite  
POSSIBLE CAUSES AND SOLUTIONS  
1. Improper ground connection:  
Make certain that the workpiece is contacted properly by the Ground Clamp and that the  
workpiece is properly cleaned near the ground clamp and the welding location.  
2. Improperly sized or excessively worn Contact Tip:  
Verify that Contact Tip is the proper size for welding wire.  
Check that the hole in the tip is not deformed or enlarged.  
Also, check that the tip is not dirty; this would prevent a good connection.

Limited 90 Day Warranty  
Harbor Freight Tools Co. makes every effort to assure that its products meet high quality and durability  
standards, and warrants to the original purchaser that this product is free from defects in materials and  
workmanship for the period of 90 days from the date of purchase. This warranty does not apply to damage  
due directly or indirectly, to misuse, abuse, negligence or accidents, repairs or alterations outside our  
facilities, criminal activity, improper installation, normal wear and tear, or to lack of maintenance. We shall  
in no event be liable for death, injuries to persons or property, or for incidental, contingent, special or  
consequential damages arising from the use of our product. Some states do not allow the exclusion or  
limitation of incidental or consequential damages, so the above limitation of exclusion may not apply to you.  
THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED,  
INCLUDING THE WARRANTIES OF MERCHANTABILITY AND FITNESS.  
To take advantage of this warranty, the product or part must be returned to us with transportation charges  
prepaid. Proof of purchase date and an explanation of the complaint must accompany the merchandise.  
If our inspection verifies the defect, we will either repair or replace the product at our election or we may elect  
to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will return  
repaired products at our expense, but if we determine there is no defect, or that the defect resulted from  
causes not within the scope of our warranty, then you must bear the cost of returning the product.  
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
