WARNING
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACE-
MAKER 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 American National Standard Z49.1 entitled: SAFETY IN WELDING AND CUTTING.
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.
WARNING
SERIOUS INJURY OR DEATH
may result if welding and cutting equipment is not properly installed, used, and
maintained. Misuse of this equipment and other unsafe practices can be hazardous. The operator, supervi-
sor, and helper must read and understand the following safety warnings and instructions before installing
or using any welding or cutting equipment, and be aware of the dangers of the welding or cutting process.
Training and proper supervision are important for a safe work place. Keep these instructions for future
use. Additional recommended safety and operating information is referenced in each section.
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.
1.02 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 semi-automatic 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.
