Arc Welding Hazards
The symbols shown below are used throughout this manual to call attention to and identify possible
hazards. When you see the symbol, watch out, and follow the related instructions to avoid the hazard. The
safety information given below is only a summary of the more complete safety information found in
Principle Safety Standards
. Read and follow all Safety Standards.
Only qualified persons should install, operate, maintain, and repair this unit.
During Operation, keep everybody, especially children, away.
5.1.2
Electric Shock
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 welding wire are electrically live. Incorrectly installed or improperly grounded
equipment is a hazard.
Do not touch live electrical parts.
Wear dry, hole-free insulating gloves and body protection
Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent
any physical contact with the work or ground.
Do not us AC output in damp areas, if movement is confined, or if there is a danger of falling.
Use AC output ONLY if required for the welding process.
If AC output is required, use remote output control if present on unit
