ELECTRIC SHOCK can kill
Touching live electrical parts can cause fatal
shock 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 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 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
following 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 unavoidable or
accidental contact with the workpiece or ground. For
these conditions, use the following equipment in order
presented: 1) a semi-automatic DC constant voltage, 2) a
DC manual (stick) welder or 3) an AC welder with reduced
open-circuit voltage. 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/
provincial 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 and 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
machines 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 when not in use.
CYLINDERS CAN EXPLODE if damaged
Compressed gas cylinders contain gas under
high pressure. If damaged, a cylinder can
explode. Since gas cylinders are normally
part of the welding process, be sure to treat
them carefully.
•
Protect compressed gas cylinders from excessive heat,
mechanical shocks, physical damage, slag, open flames,
sparks and arcs.
•
Install cylinders in an upright position by securing to a
stationary support or cylinder rack to prevent falling or
tipping.
•
Keep cylinders away from any welding, cutting or other
electrical circuits.
•
Never drape a welding electrode or cutting torch over a
gas cylinder.
•
Never allow a welding electrode or cutting torch to touch
any cylinder.
•
Never weld on a pressurized cylinder – explosion will
result.
•
Use only correct compressed gas cylinders, regulators,
hoses and fittings designed for the specific application;
maintain them and associated parts in good condition.
•
Turn face away from valve outlet when opening cylinder
valve. Do not stand in front of or behind the regulator
when opening the valve.
•
Keep protective cap in place over valve except when
cylinder is in use or connected for use.
•
Use the right equipment, correct procedures and sufficient
number of persons to lift and move cylinders.
•
Read and follow instructions on compressed gas
cylinders, associated equipment, and Compressed
Gas Association (CGA) publication P-1 listed in Safety
Standards.
