Hazard In Welding Power While In Use - Hyundai Dynamic auto 350M Operation Manual

1-2-1. Hazards in Welding Power Source While in Use
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 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.
•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.
•Do not drape cables over your body.
•If earth grounding of the workpiece is required, ground it directly with a separate cable-do not use
work clamp or work cable.
•Do not touch electrode if you are in contact with the work, ground, or another electrode from a
different machine.
•Use only well-maintained equipment. Repair or replace damaged parts at once. Maintain unit
according to this manual.
•Wear a safety harness if working above floor level.
•Keep all panels and covers securely in place.
•Clamp work cable with good metal-to-metal contact to workpiece or workcable as near the weld as
practical.
•Insulate work clamp when not connected to workpiece to prevent contact with any metal object.
•Do not connect more than one electrode or work cable to any single weld output terminal.
