4BUILDUP OF GAS can injure or kill.
• Shut off shielding gas supply when not in use.
• Always ventilate confined spaces or useapproved air supplied
respirator.
4MAGNETIC FIELDS can affect ImplantedMedical Devices.
• Wearers of Pacemakers and other ImplantedMedical Devices
should keep away.
• Implanted Medical Device wearers should consult their
doctorand the device manufacturer before going near arc
welding, spotwelding, gouging, plasma arc cutting, or induction
heating operations.
4NOISE can damage hearing.
Noise from some processes or equipment candamage hearing.
• Wear approved ear protection if noise level is high.
4CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under highpressure. If
damaged, a cylinder can explode. Sincegas cylinders are
normally part of the weldingprocess, 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
stationarysupport or cylinder rack to prevent falling or tipping.
• Keep cylinders away from any welding or other electrical circuits.
• Never drape a welding torch over a gas cylinder.
• Never allow a welding electrode to touch any cylinder.
• Never weld on a pressurized cylinder − explosion will result.
• Use only correct shielding 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.
• Keep protective cap in place over valve except when cylinder is
inuse or connected for use.
• Use the right equipment, correct procedures, and sufficient num-
ber 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.
4FIRE OR EXPLOSION hazard.
• Do not install or place unit on, over, or nearcombustible 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

FALLING UNIT can cause injury.
• Use lifting eye to lift unit only, NOT runninggear, gas cylinders, or
any other accessories.
• Use equipment of adequate capacity to lift andsupport unit.
• If using lift forks to move unit, be sure forks arelong enough to
extend beyond opposite side ofunit.
4OVERUSE can cause OVERHEATING
• Allow cooling period; follow rated duty cycle.
• Reduce current or reduce duty cycle beforestarting to weld
again.
• Do not block or filter airflow to unit.
4FLYING SPARKS can cause injury.
• Wear a face shield to protect eyes and face.
• Shape tungsten electrode only on grinder withproper guards in a
safe location wearing properface, hand, and body protection.
• Sparks can cause fires — keep flammables away.
4MOVING PARTS can cause injury.
• Keep away from moving parts.
• Keep away from pinch points such as driverolls.
4WELDING WIRE can cause injury.
• Do not press gun trigger until instructed to doso.
• Do not point gun toward any part of the body,other people, or any
metal when threading welding wire.
4MOVING PARTS can cause injury.
• Keep away from moving parts such as fans.
• Keep all doors, panels, covers, and guardsclosed and securely
in place.
• Have only qualified persons remove doors, panels, covers,
or guards for maintenance as necessary.
• Reinstall doors, panels, covers, or guards when maintenance is
finished and before reconnecting input power.
4H.F. RADIATION can cause interference.
• High-frequency (H.F.) can interfere with radionavigation, safety
services, computers, andcommunications equipment.
• Have only qualified persons familiar withelectronic equipment
perform this installation.
• The user is responsible for having a qualified electrician prompt-
ly correct any interference problem resulting from the installa-
tion.
• Have the installation regularly checked and maintained.
• Keep high-frequency source doors and panels tightly shut,
keep spark gaps at correct setting, and use grounding and
shielding tominimize the possibility of interference.
