When you seethe symbol, watch out, and follow the related instructions toavoid the hazard. The safety information given below is onlya summary of the more complete safety information found inthe Safety Standards listed in Section 1-4.

8 The electrode and work circuit iselectrically live whenever the output is on. The inputpower circuit and machine internal circuits are alsolive when power is on. In semiautomatic or automatic wire welding, thewire, wire reel, drive roll housing, and all metal parts touching thewelding wire are electrically live. Incorrectly installed or improperlygrounded equipment is a not touch live electrical dry, hole-free insulating gloves and body yourself from work and ground using dry insulating matsor covers big enough to prevent any physical contact with the workor not use AC output in damp areas, if movement is confined, or ifthere is a danger of AC output ONLY if required for the welding AC output is required, use remote output control if present input power or stop engine before installing orservicing this equipment.
