Manual 0-5187 1-1 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.
SECTION 1:
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.
