Electrical Safety
ELECTRIC SHOCK can KILL.
1.Turn off, disconnect power, and
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.
3.Connect to grounded, GFCI protected power supply only.
4.Do not use near water or damp objects.
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.
6.Do not expose welders to rain or wet conditions.
Water entering a welder will increase the risk of electric shock.
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.
8.Do not use outdoors.
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.
10.Use care not to touch the welding tip to grounded material whenever the unit is plugged in. Electric shock, fire, or burns may happen if appropriate precautions are not taken.

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.
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.
Make sure there is adequate surrounding workspace. Keep the work area free of obstructions,
grease, oil, trash, and other debris.
4.Do not operate welders in atmospheres containing dangerously reactive or 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.
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.
6.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 hazard.
7.Do not dispose of hot slag in containers holding combustible materials.
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.
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.
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.
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.
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.
SAFETY
SETUP
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.
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.
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.
SAVE THESE INSTRUCTIONS.

Grounding
TO PREVENT ELECTRIC SHOCK AND DEATH FROM INCORRECT GROUNDING WIRE CONNECTION:
Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Have a plug installed by a certified electrician. Do not use the Welder if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the
outlet, have a proper outlet installed by a qualified electrician.
Grounded Welders
1. The grounding prong in the plug is connected |
2. The Welder must be plugged into an appropriate |
through the green wire inside the cord to the |
outlet, properly installed and grounded in |
grounding system in the Welder. The green wire |
accordance with all codes and ordinances. |
in the cord must be the only wire connected to |
|
the Welder’s grounding system and must never |
|
be attached to an electrically “live” terminal. |
|
Extension Cords |
|
1.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.
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 welder damage.
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.
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.
5.If you are using one extension cord for more than one welder, add the nameplate amperes and use the sum to determine the required minimum cord size.
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 the 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 the extension cords from sharp objects, excessive heat, and damp or wet areas.

IMPORTANT:
Securely hold onto the end of the welding wire and keep tension on it during the following steps.
If this is not done, the welding wire will unravel and create a tangled “bird’s nest”, wasting wire.
8.Cut off all bent and crimped wire.
Make sure that the cut end has no burrs or sharp edges; cut again if needed.
9.Keep tension on the wire and guide at least 12 inches of wire into the Wire Liners.
10.Swing the Feed Swing Arm closed, and swing the Feed Tensioner across the tip of the Arm, to latch it. Make sure the Welding Wire is resting in the top groove of the Feed Roller, then turn the
Feed Tensioner clockwise 
a couple of turns. After the wire is held by the Feed
Tensioner, you may release it.
11.Pull the Nozzle to remove it.
12.Using the third oval hole on the Multi-wrench, turn the Contact Tip counterclockwise 
and remove.
13.Lay the Gun Cable out in a straight line so that the wire moves through it easily. Leave the cover open, so that the feed mechanism can be observed.
