GENERAL INFORMATION

1.01 Arc Welding Hazards

WARNING

ELECTRIC SHOCK can kill.

Touching live electrical parts can cause fatal

shocks or severe burns. The electrode and

work circuit is electrically live whenever the

output is on. The input power circuit and ma-

chine internal circuits are also live when power

is ON. In semiautomatic or automatic wire

welding, the wire, wire reel, drive roll housing,

and all metal parts touching the welding wire

are electrically live. Incorrectly installed or

improperly grounded equipment is a hazard.

1. DO NOT touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protec-

tion.

3. Insulate yourself from work and ground using dry

insulating mats or covers.

4. Disconnect input power or stop engine before install-

ing or servicing this equipment. Lock input power

disconnect switch open, or remove line fuses so power

cannot be turned on accidentally.

5. Properly install and ground this equipment according

to its Owner’s Manual and national, state, and local

codes.

6. Turn OFF all equipment when not in use. Disconnect

power to equipment if it will be left unattended or out

of service.

7. Use fully insulated electrode holders. Never dip holder

in water to cool it or lay it down on the ground or the

work surface. DO NOT touch holders connected to

two welding machines at the same time or touch other

people with the holder or electrode.

8. DO NOT use worn, damaged, undersized, or poorly

spliced cables.

9. DO NOT wrap cables around your body.
10. Ground the workpiece to a good electrical (earth)

ground.

11. DO NOT touch electrode while in contact with the work

(ground) circuit.

12. Use only well-maintained equipment. Repair or replace

damaged parts at once.

13. In confined spaces or damp locations, DO NOT use

a welder with AC output unless it is equipped with a

voltage reducer. Use equipment with DC output.

14. Wear a safety harness to prevent falling if working

above floor level.

15. Keep all panels and covers securely in place.

ARC WELDING SAFETY INSTRUCTIONS AND WARNINGS

!

WARNING

PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY.

PACEMAKER WEARERS KEEP AWAY UNTIL CONSULTING YOUR DOCTOR. Do NOT LOSE THESE INSTRUCTIONS.

READ OPERATING/INSTRUCTION MANUAL BEFORE INSTALLING, OPERATING OR SERVICING THIS EQUIPMENT.
Welding products and welding processes can cause serious injury or death, or damage to other equipment or property,

if the operator does not strictly observe all safety rules and take precautionary actions.
Safe practices have developed from past experience in the use of welding and cutting. These practices must be learned

through study and training before using this equipment. Some of these practices apply to equipment connected to

power lines; other practices apply to engine driven equipment. Anyone not having extensive training in welding and

cutting practices should not attempt to weld.
Safe practices are outlined in the Australian Standard AS1674.2-2007 entitled: Safety in welding and allied processes

Part 2: Electrical. This publication and other guides to what you should learn before operating this equipment are

listed at the end of these safety precautions. HAVE ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR

WORK PERFORMED ONLY BY QUALIFIED PEOPLE.
