NOISE 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
4FALLING 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.

4ARC WELDING can cause interference.
• Electromagnetic energy can interfere withsensitive electronic
• Be sure all equipment in the welding area iselectromagnetically
• To reduce possible interference, keep weld cables as short
• Locate welding operation 100 meters from any sensitive elec-
• Be sure this welding machine is installed and grounded
• If interference still occurs, the user must take extra measures
