SAFETY INSTRUCTIONS
Do not attempt to use this equipment until you have thoroughly read all operating and maintenance man- uals supplied with your equipment and any related welding machine it will be used with. They include important safety precautions, operating and mainte- nance instructions and parts lists.
WARNING
ELECTRIC SHOCK can kill.
•Do not touch electrically live parts such as output terminals or internal wiring.
•Insulate yourself from the work and ground.

•Do not weld upon containers which have held combustibles.
ARC RAYS can burn.
•Wear eye, ear and body protection.
FUMES AND GASES can be dangerous.
• Although the removal of the particu-
