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 metal-

working processes, be sure to treat them carefully.

� Protect compressed gas cylinders from excessive heat, mechani-

cal shocks, physical damage, slag, open flame, sparks, and arcs.

� Install and secure cylinders in an upright position by chaining them

to a stationary support or equipment cylinder rack to prevent falling

or tipping.

� Keep cylinders away from any cutting or other electrical circuits.

� Never allow electrical contact between a plasma arc torch and a

cylinder.

Additional Hazards For Installation, Operation, And Maintenance

HOT PARTS can burn.

� Do not touch hot parts bare handed.

� Allow cooling period before working on equipment.

� To handle hot parts, use proper tools and/or wear

heavy, insulated welding gloves and clothing to

prevent burns.

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.

FLYING METAL or DIRT can injure

eyes.

� Wear safety glasses with side shields or wear face

shield.

ELECTRIC AND MAGNETIC FIELDS

(EMF) can affect Implanted Medical

Devices.

� Wearers of Pacemakers and other Implanted Med-

ical Devices should keep away.

� Implanted Medical Device wearers should consult their doctor and

the device manufacturer before going near arc welding, spot weld-

ing, gouging, plasma arc cutting, or induction heating operations.

OVERUSE can cause

OVERHEATING.

� Allow cooling period; follow rated duty cycle.

� Never cut 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.

� Reduce amperage (thickness) or reduce duty cycle before starting

to cut again.

EXPLODING HYDROGEN hazard.

� When cutting aluminum underwater or with the

water touching the underside of the aluminum, free

hydrogen gas can collect under the workpiece.

� See your cutting engineer and water table instruc-

tions for help.

BATTERY EXPLOSION can injure.

� Do not use plasma cutter to charge batteries or

jump start vehicles unless it has a battery charging

feature designed for this purpose.

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.

FIRE OR EXPLOSION hazard.

� Do not locate unit on, over, or near combustible

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.

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.
