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 weld-

ing process, be sure to treat them carefully.

� Protect compressed gas cylinders from excessive heat, mechani-

cal 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 or other electrical circuits.

� Never drape a welding torch over a gas cylinder.

� Never allow a welding electrode to touch any cylinder.

Additional Hazards For Installation, Operation, And Maintenance

FIRE OR EXPLOSION hazard.

� Do not install or place unit on, over, or near com-

bustible 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 EQUIPMENT can injure.

� Use lifting eye to lift unit only, NOT running gear,

gas cylinders, or any other accessories.

� Use correct procedures and equipment of ad-

equate capacity to lift and support unit.

� If using lift forks to move unit, be sure forks are long enough to ex-

tend 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 manually

lifting heavy parts or equipment.

OVERUSE can cause

OVERHEATING.

� Allow cooling period; follow rated duty cycle.

� Reduce current or reduce duty cycle before start-

ing to weld again.

� Do not block or filter airflow to unit.

FLYING SPARKS can injure.

� Wear a face shield to protect eyes and face.

� Shape tungsten electrode only on grinder with

proper guards in a safe location wearing proper

face, hand, and body protection.

� Sparks can cause fires—keep flammables away.

STATIC (ESD) can damage PC

boards.

� Put on grounded wrist strap BEFORE handling

boards or parts.

� Use proper static-proof bags and boxes to store,

move, or ship PC boards.

MOVING PARTS can injure.

� Keep away from moving parts.

� Keep away from pinch points such as drive rolls.

� 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 proper equipment, correct procedures, and sufficient

number of persons to lift, move, and transport cylinders.

� Read and follow instructions on compressed gas cylinders, asso-

ciated equipment, and Compressed Gas Association (CGA) publi-

cation P-1 listed in Safety Standards.

WELDING WIRE can injure.

� Do not press gun trigger until instructed to do so.

� Do not point gun toward any part of the body, other

people, or any metal when threading welding wire.

BATTERY EXPLOSION can injure.

� Do not use welder to charge batteries or jump start

vehicles unless it has a battery charging feature

designed for this purpose.

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.

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 installation, maintenance, and service according to the

Owner's Manuals, industry standards, and national, state, and lo-

cal codes.

H.F. RADIATION can cause

interference.

� High-frequency (H.F.) can interfere with radio navi-

gation, safety services, computers, and communi-

cations equipment.

� Have only qualified persons familiar with electronic equipment per-

form this installation.

� The user is responsible for having a qualified electrician promptly

correct any interference problem resulting from the installation.

� If notified by the FCC about interference, stop using the equipment

at once.

� 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 to

minimize the possibility of interference.
