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 machine 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 weld-
ing 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 protection.
3. Insulate yourself from work and ground using dry insulating
mats or covers.
4. Disconnect input power or stop engine before installing 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 dam-
aged 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.
WARNING
ARC RAYS can burn eyes and skin; NOISE can
damage hearing. Arc rays from the welding process
produce intense heat and strong ultraviolet rays that
can burn eyes and skin. Noise from some processes
can damage hearing.
1. Use a Welding Helmet or Welding Faceshield fitted with a
proper shade of filter (see ANSI Z49.1 and AS 1674 listed in
safety Standards) to protect your face and eyes when welding
or watching.
2. Wear approved safety glasses. Side shields recommended.
3. Use protective screens or barriers to protect others from flash
and glare; warn others not to watch the arc.
4. Wear protective clothing made from durable, flame-resistant
material (wool and leather) and foot protection.
5. Use approved ear plugs or ear muffs if noise level is high.
6. Never wear contact lenses while welding.
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.
