Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use machines or power tools in damp or wet
locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically
powered tools in the presence of flammable gases or liquids.
3. Keep children away. Children must never be allowed in the work area. Do not let them
handle machines, tools, or extension cords.
For technical questions, please call 1-800-444-3353.
Page 2SKU 55250
4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit
rust. Always lock up tools and keep out of reach of children.
5. Do not force tool. It will do the job better and more safely at the rate for which it was
intended. Do not use inappropriate attachments in an attempt to exceed the tool capacity.
6. Use the right tool for the job. Do not attempt to force a small tool or attachment to do
the work of a larger industrial tool. There are certain applications for which this tool was
designed. Do not modify this tool and do not use this tool for a purpose for which it was
not intended.
7. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving
parts. Protective, electrically nonconductive clothes and nonskid footwear are
recommended when working. Wear restrictive hair covering to contain long hair.
8. Use protective gear. Always wear ANSI approved, arc shaded, impact safety full face
shield when arc welding. Wear an ANSI approved dust mask or respirator when working
around metal, chemical dusts, fumes and mists. Always wear ANSI approved welding
gear: leather gloves, leather apron, and shoes.
9. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines.
10. Maintain tools with care. Keep tools sharp and clean for better and safer performance.
Follow instructions for lubricating and changing accessories. Inspect tool cords periodically
and, if damaged, have them repaired by an authorized technician. The handles must be
kept clean, dry, and free from oil and grease at all times.
11. Disconnect power. Unplug tool when not in use.
12. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are
removed from the tool or machine work surface before plugging it in.
13. Avoid unintentional starting. Be sure the switch is in the Off position when not in use
and before plugging in. Do not carry any tool with your finger on the trigger, whether it is
plugged in or not.
14. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
15. Check for damaged parts. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts or
mounting fixtures; and any other condition that may affect proper operation. Any part
that is damaged should be properly repaired or replaced by a qualified technician. Do
not use the tool if any switch does not turn On and Off properly.
16. Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.
17. Replacement parts and accessories. When servicing, use only identical replacement
parts. Use of any other parts will void the warranty. Only use accessories intended for
use with this tool. Approved accessories are available from Harbor Freight Tools.
18. Do not operate tool if under the influence of alcohol or drugs. Read warning labels
on prescriptions to determine if your judgment or reflexes are impaired while taking
drugs. If there is any doubt, do not operate the tool.
For technical questions, please call 1-800-444-3353.

19. Maintenance. For your safety, service and maintenance should be performed regularly
by a qualified technician.
20. Use proper size and type extension cord. If an extension cord is required, it must be
of the proper size and type to supply the correct current to the tool without heating up.
Otherwise, the extension cord could melt and catch fire, or cause electrical damage to
the tool. This tool requires use of an 220 VAC extension cord of 20 amps minimum
capability (up to 30 feet), with wire size rated at 10 AWG. Longer extension cords require
larger size wire. If you are using the tool outdoors, use an extension cord rated for
outdoor use (signified by “WA” on the jacket).
21. Pacemaker safety warning. People with pacemakers should consult with their
physician(s) before using this product; operation of equipment in close proximity to a
heart pacemaker could cause interference or failure of the pacemaker.
Note: Performance of this tool may vary depending on variations in local line voltage. Extension cord usage may also affect tool performance.
Warning: The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be
built into this product, but must be supplied by the operator.
Arc Welding Safety Warnings and Precautions
1. Avoid electrical shock. Do not permit electrically live parts, cables, or electrodes to
contact skin, clothing, or gloves. Protective clothing should be free of holes, dry, and
ANSI approved.
This unit draws enough current to cause serious injury or death. Before turning the
welder on, check the electrode holder to be sure that there are no protruding screw
heads, and that all insulation is secure. Do not weld unless you are insulated from ground
and the work piece.
2. Avoid breathing fumes or gases. They can cause serious health problems. Use an
active ventilation system directly above the welding area. Keep your head out of the
fumes.
3. Avoid eye and body damage. Arc rays and infrared radiation can injure eyes and burn
skin. Wear ANSI approved eye and body protection. Do not allow viewing by visitors
without proper eye and body protection. Use a Face Shield with arc shaded filter plate.
4. Know proper arc welding practices. Read and understand this instruction manual,
and well as your employer’s safety practices for arc welding.
5. Avoid fire and explosion. Remove flammable and explosive material from at least 35
feet from the welding arc to prevent welding sparks or molten metal from starting a fire.
Keep a type ABC fire extinguisher within easy reach. Thoroughly clean the object being
welded of any paint, grease, or other foreign material.
6. This product, when used for welding and similar applications, produces chemicals known
to the State of California to cause cancer and birth defects (or other reproductive harm).

et seq.
)

7. Connect only to a code approved power source. Connect only to a grounding power
source conforming to the National Electrical Code and Local Codes.
8. Wear proper clothing when welding. Use flameproof, welding-type gloves. Wear
cuffless pants and pocketless shirt. Both must be free of oil and grease. Wear hightopped, safety shoes with rubber soles.
