FALLING EQUIPMENT can injure.
 Use equipment of adequate 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 manu-
ally lifting heavy parts or equipment.
MOVING PARTS can injure.
 Keep 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
combustible 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 maintenance and service according to the Owner’s
Manuals, industry standards, and national, state, and local
codes.
1-3. Arc Welding And Plasma Cutting Hazards
Touching live electrical parts can cause fatal shock
s
or severe burns. The electrode and work circuit i
s
electrically live whenever the output is on. The inpu
t
power circuit and machine internal circuits are als
o
live when power is on. In semiautomatic or automati
c
wire welding, the wire, wire reel, drive roll housing
,
and all metal parts touching the welding wire ar
e
electrically live. Incorrectly installed or improperl
y
grounded equipment is a hazard.
 Do not touch live electrical parts.
ELECTRIC SHOCK can kill.
 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 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
locations 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!
 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, 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 metal
and sparks.
 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 touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
 Do not touch electrode holders connected to two welding ma-
chines at the same time since double open-circuit voltage will be
present.
 Use only well-maintained equipment. Repair or replace damaged
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.
 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. Disconnect cable for process not in
use.
SIGNIFICANT DC VOLTAGE exists in inverter pow-
er sources AFTER removal of input power.
 Turn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section
before touching any parts.
HOT PARTS can burn.
 Do not touch hot parts bare handed.
 Allow cooling period before working on equip-
ment.
 To handle hot parts, use proper tools and/or
wear heavy, insulated welding gloves and
clothing to prevent burns.
