ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal
shocks or severe burns. The input power circuit
and machine internal circuits are also live when
power is on. Incorrectly installed or improperly
grounded equipment is a hazard.
� Do not touch live electrical parts.
� Disconnect input power before installing or servicing this equip-
ment. Lockout/tagout input power according to OSHA 29 CFR
1910.147 (see Safety Standards).
� Properly install, ground, and operate 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.
� Frequently inspect input power cord and ground conductor for
damage or bare wiring – replace immediately if damaged – bare
wiring can kill.
FALLING EQUIPMENT can injure.
� Use correct procedures and equipment of ad-
equate capacity to lift and support unit.
� If using lift forks to move unit, be sure forks are
long enough to extend beyond opposite side of
unit.
� Keep equipment (cables and cords) away from moving vehicles
when working from an aerial location.
� Follow the guidelines in the Applications Manual for the Revised
NIOSH Lifting Equation (Publication No. 94-110) when manually
lifting heavy parts or equipment.

Arc Welding And Plasma Cutting Hazards
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 cir-
cuits are also live when power is on. In semiauto-
matic or automatic wire welding, the wire, wire
reel, drive roll housing, and all metal parts touching
the welding wire are electrically live. Incorrectly in-
stalled 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 weld output in damp, wet, or confined spaces, or if
there is a danger of falling.
� Use AC output ONLY if required for the welding or cutting process.
� If AC output is required, use remote output control if present on
unit.
� Additional safety precautions are required when any of the follow-
ing electrically hazardous conditions are present: in damp loca-
tions or while wearing wet clothing; on metal structures such as
floors, gratings, or scaffolds; when in cramped positions such as
sitting, kneeling, or lying; or when there is a high risk of unavoid-
able or accidental contact with the workpiece or ground. For these
conditions, use the following equipment in order presented: 1) a
semiautomatic DC constant voltage (wire) welder, 2) a DC manual
(stick) welder, or 3) an AC welder with reduced open-circuit volt-
age. In most situations, use of a DC, constant voltage wire welder
is recommended. And, do not work alone!

MOVING PARTS can injure.
� Keep hands, hair, loose clothing, jewelry, tools,
and other objects away from moving parts such as
fans.
� Keep all doors, panels, covers, and guards closed
and securely in place.
� Have only qualified persons remove doors, panels, covers, or
guards for maintenance and troubleshooting as necessary.
� Reinstall doors, panels, covers, or guards when maintenance is
finished and before reconnecting input power.
FIRE OR EXPLOSION hazard.
� Do not install or place unit on, over, or near com-
bustible surfaces.
� Do not install unit near flammables.
� Do not overload building wiring - be sure power
supply system is properly sized, rated, and protected to handle
this unit.
READ INSTRUCTIONS.
� Read and follow all labels and the Owner's Manual
carefully before installing, operating, or servicing
unit. Read the safety information at the beginning
of the manual and in each section.
� Use only genuine replacement parts from the manufacturer.
� Perform installation, maintenance, and service according to the
Owner's Manuals, industry standards, and national, state, and lo-
cal codes.
� Disconnect input power or stop engine before installing or servic-
ing this equipment. Lockout/tagout input power according to
OSHA 29 CFR 1910.147 (see Safety Standards).
� Properly install, ground, and operate 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 conduc-
tor first — double-check connections.
� Keep cords dry, free of oil and grease, and protected from hot met-
al and sparks.
� Frequently inspect input power cord and ground conductor for
damage or bare wiring — replace immediately if damaged — bare
wiring can kill.
� Turn off all equipment when not in use.
� Do not use worn, damaged, undersized, or repaired 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 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 manual.
� Do not touch electrode holders connected to two welding ma-
chines at the same time since double open-circuit voltage will be
present.
� 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.
