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/INSTRU-
CTION 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.
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.
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.
WARNING
1.1 Arc Welding Damage
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 European Standard EN60974-1 entitled: Safety in
welding and allied processes Part 2: Electrical HAVE ALL INSTALLATION, OPERATION,
MAINTENANCE, ANDREPAIR WORK PERFORMED ONLY BY QUALIFIED PEOPLE.
