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 partstouchingthewelding wire areelectrically 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.

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 connectedto 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 notuseworn, damaged,undersized,or poorly splicedcables.
-
Do not drape cables over your body.
-
If earth grounding of the workpiece is required, ground it directly
with a separate cable.

parts at once. Maintain unit according to 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 worktable as near the weld as practical.
-
Insulatework clamp when not connectedto workpiece toprevent
contact with any metal object.
-
Do not connect more than one electrode or work cable to any
single weld output terminal.

before touching any parts.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.

-
Keep your head out of the fumes. Do not breathe the fumes.
-
If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.
-
If ventilation is poor, use an approved air-supplied respirator.
-
Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instructions for metals, consumables, coatings,
cleaners, and degreasers.
-
Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watch-
person nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the
breathing air is safe.
-
Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapors to
form highly toxic and irritating gases.
-
Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the
weld area, the area is well ventilated, and if necessary, while
wearing an air-supplied respirator. The coatings and any metals
containing these elements can give off toxic fumes if welded.
