EXPLODING PARTS can injure.

D On inverter power sources, failed parts can ex-

plode or cause other parts to explode when

power is applied. Always wear a face shield

and long sleeves when servicing inverters.

FLYING SPARKS can cause injury.

Sparks and hot metal blow out from the cutting arc.

Chipping and grinding cause flying metal.

Wear approved face shield or safety goggles with side shields.

Wear proper body protection to protect skin.

Wear flame-resistant ear plugs or ear muffs to prevent sparks from

entering ears.

ARC RAYS can burn eyes and skin.

Arc rays from the cutting process produce intense

visible and invisible (ultraviolet and infrared) rays

that can burn eyes and skin.

Wear face protection (helmet or shield) with correct shade of filter to

protect your face and eyes when cutting or watching. ANSI Z49.1

(see Safety Standards) suggests a No. 9 shade (with No. 8 as mini-

mum) for all cutting currents less than 300 amperes. Z49.1 adds

that lighter filter shades may be used when the arc is hidden by the

workpiece. As this is normally the case with low current cutting, the

shades suggested in Table 1 are provided for the operator's conve-

nience.

Wear approved safety glasses with side shields under your helmet

or shield.

Use protective screens or barriers to protect others from flash and

glare; warn others not to watch the arc.

Wear protective clothing made from durable, flame-resistant

material (leather and wool) and foot protection.

NOISE can damage hearing.

Prolonged noise from some cutting applications can

damage hearing if levels exceed limits specified by

OSHA (see Safety Standards).

Use approved ear plugs or ear muffs if noise level is high.

Warn others nearby about noise hazard.

FUMES AND GASES can be hazardous

Cutting produces fumes and gases. Breathing

these fumes and gases can be hazardous to

your health.

Keep your head out of the fumes. Do not breathe the fumes.

Minimum Shade Number

If inside, ventilate the area and/or use exhaust at the arc to remove

cutting fumes and gases.

If ventilation is poor, use an approved air-supplied respirator.

Read the Material Safety Data Sheets (MSDSs) and the manufac-

turer's instruction for metals to be cut, coatings, and cleaners.

Work in a confined space only if it is well ventilated, or while wearing

an air-supplied respirator. Fumes from cutting and oxygen deple-

tion can alter air quality causing injury or death. Be sure the

breathing air is safe.

Do not cut in locations near degreasing, cleaning, or spraying oper-

ations. The heat and rays of the arc can react with vapors to form

highly toxic and irritating gases.

Do not cut on coated metals, such as galvanized, lead, or cadmium

plated steel, unless the coating is removed from the cutting area,

the area is well ventilated, and if necessary, while wearing an air-

supplied respirator. The coatings and any metals containing these

elements can give off toxic fumes when cut.

Do not cut containers with toxic or reactive materials inside or

containers that have held toxic or reactive materials – they must be

emptied and properly cleaned first.

PLASMA ARC can cause injury.

The heat from the plasma arc can cause serious

burns. The force of the arc adds greatly to the burn

hazard. The intensely hot and powerful arc can

quickly cut through gloves and tissue.

Keep away from the torch tip.

Do not grip material near the cutting path.

The pilot arc can cause burns – keep away from torch tip when trig-

ger is pressed.

Wear proper flame-retardant clothing covering all exposed body ar-

eas.

Point torch away from your body and toward work when pressing

the torch trigger – pilot arc comes on immediately.

Turn off power source and disconnect input power before disas-

sembling torch or changing torch parts.

Use only torch(es) specified in the Owner's Manual.

CYLINDERS can explode if damaged.

Gas cylinders contain gas under high pressure. If

damaged, a cylinder can explode. Since gas cylin-

ders are normally part of metalworking processes,

be sure to treat them carefully.

Protect compressed gas cylinders from excessive heat, mechani-

cal shocks, 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.

Never cut on a pressurized cylinder – explosion will result.

Use only correct gas cylinders, regulators, hoses, and fittings de-

signed 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 in

use or connected for use.

Read and follow instructions on compressed gas cylinders, asso-

ciated equipment, and CGA publication P-1 listed in Safety

Standards.
