1.2 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 the Safety
Standards listed in Section 1-4. Read and follow all Safety Standards.
Electric Shock can kill.
•
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 use 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.
•
Disconnect input power or stop engine before installing or servicing this
equipment. Lockout/tagout input power according to OSHA 29 CFR
1910.147 (see Safety Standards).
•
Properly install and ground this equipment according to its Owner's Manual
and national, state, and local codes.
•
Always verify the supply ground – check and be sure that input power cord
ground wire is properly connected to ground terminal in disconnect box or
that cord plug is connected to a properly grounded receptacle outlet.
•
When making input connections attach proper grounding conductor first –
double-check connections.
•
Frequently inspect input power cord for damage or bare wiring – replace
cord immediately if damaged – bare wiring can kill.
•
Turn off all equipment when not in use.
•
Do not use worn, damaged, undersized, or poorly spliced cables.
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.
