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 gas metal
arc welding (GMAW), 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 insulated 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 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 GMAW DC
constant voltage (wire) welder, 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 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 con-
nected 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 greases and protected from hot
metal and sparks.
• Frequently inspect 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 sta-
tionary 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 the 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.
