SECTION 1:

GENERAL INFORMATION

1.01 Notes, Cautions and Warnings

Throughout this manual, notes, cautions, and warnings

are used to highlight important information. These high-

lights are categorized as follows:

NOTE

An operation, procedure, or background informa-

tion which requires additional emphasis or is help-

ful in efficient operation of the system.

CAUTION

A procedure which, if not properly followed, may

cause damage to the equipment.

WARNING

A procedure which, if not properly followed, may

cause injury to the operator or others in the oper-

ating area.

1.02 Important Safety Precautions

WARNINGS

OPERATION AND MAINTENANCE OF

PLASMA ARC EQUIPMENT CAN BE DAN-

GEROUS AND HAZARDOUS TO YOUR

HEALTH.

Plasma arc cutting produces intense electric and

magnetic emissions that may interfere with the

proper function of cardiac pacemakers, hearing

aids, or other electronic health equipment. Per-

sons who work near plasma arc cutting applica-

tions should consult their medical health profes-

sional and the manufacturer of the health

equipment to determine whether a hazard exists.

To prevent possible injury, read, understand and

follow all warnings, safety precautions and in-

structions before using the equipment. Call 1-603-

298-5711 or your local distributor if you have any

questions.

GASESANDFUMES

Gasesandfumes produced during the plasmacuttingprocess

can be dangerous and hazardous to your health.

• Keepall fumes and gases fromthebreathingarea. Keep

yourheadoutof the welding fume plume.

• Use an air-supplied respirator if ventilation is not ad-

equate to remove all fumes and gases.

• The kinds of fumes and gases from the plasma arc de-

pend on the kind of metal being used, coatings on the

metal, and the different processes. You must be very

carefulwhen cutting orweldingany metals which may

contain one or more of the following:

Antimony Chromium Mercury

Arsenic Cobalt Nickel

Barium Copper Selenium

Beryllium Lead Silver

Cadmium Manganese Vanadium

• Always read the Material Safety Data Sheets

(MSDS) that should be supplied with the material

you are using. These MSDSs will give you the in-

formation regarding the kind and amount of fumes

and gases that may be dangerous to your health.

• For information on how to test for fumes and gases

in your workplace, refer to item 1 in Subsection 1.03,

Publications in this manual.

• Use special equipment, such as water or down draft

cutting tables, to capture fumes and gases.

• Do not use the plasma torch in an area where com-

bustible or explosive gases or materials are located.

• Phosgene, a toxic gas, is generated from the vapors

of chlorinated solvents and cleansers. Remove all

sources of these vapors.

• This product, when used for welding or cutting,

produces fumes or gases which contain chemicals

known to the State of California to cause birth de-

fects and, in some cases, cancer. (California Health

& Safety Code Sec. 25249.5 et seq.)

GENERAL INFORMATION 1-2 Manual 0-4691

ELECTRICSHOCK

Electric Shock can injure or kill. The plasma arc process uses

and produces high voltage electrical energy. This electric en-

ergy can cause severe or fatal shock to the operator or others

intheworkplace.

• Nevertouchanypartsthatareelectrically“live”or“hot.”

• Wear dry gloves and clothing. Insulate yourself from

the work piece or other parts of the welding circuit.

• Repairorreplaceall worn or damaged parts.

• Extracaremustbe taken when the workplace ismoistor

damp.

• Installandmaintain equipment according to NECcode,

refer to item 9 in Subsection 1.03, Publications.

• Disconnectpowersourcebefore performing any service

orrepairs.

• Read and follow all the instructions in the Operating

Manual.

FIREANDEXPLOSION

Fire and explosion can be caused by hot slag, sparks, or the

plasmaarc.

• Besurethere is no combustible orflammablematerialin

the workplace. Any material that cannot be removed

mustbe protected.

• Ventilateallflammableorexplosivevaporsfromthework-

place.

• Do not cut or weld on containers that may have held

combustibles.

• Provideafirewatch when working in an areawherefire

hazardsmayexist.

• Hydrogengasmaybeformedandtrappedunderalumi-

numworkpieceswhentheyarecutunderwaterorwhile

usinga water table. DO NOT cut aluminum alloys un-

derwater or on a water table unless the hydrogen gas

canbe eliminated or dissipated. Trappedhydrogengas

that is ignited will cause an explosion.

NOISE

Noisecancausepermanenthearing loss. Plasma arc processes

can cause noise levels to exceed safe limits. You must protect

your ears from loud noise to prevent permanent loss of hear-

ing.

• To protectyourhearingfromloudnoise,wearprotective

ear plugs and/or ear muffs. Protect others in the work-

place.

• Noiselevels should bemeasured to be surethe decibels

(sound) do not exceed safe levels.

• For information on how to test for noise, see item 1 in

Subsection 1.03, Publications, in this manual.

PLASMAARC RAYS

PlasmaArc Rays caninjureyoureyesandburnyourskin. The

plasmaarc process producesverybright ultra violet andinfra

redlight. Thesearc rays will damage youreyesandburnyour

skin if you are not properly protected.

• To protect your eyes, always wear a welding helmet or

shield. Alsoalwayswearsafetyglasseswithsideshields,

goggles or other protective eye wear.

• Wear welding gloves and suitable clothing to protect

your skin from the arc rays and sparks.

• Keep helmet and safety glasses in good condition. Re-

place lenses when cracked, chipped or dirty.

• Protect others in the work area from the arc rays. Use

protective booths, screens or shields.

• Use the shade of lens as suggested in the following per

ANSI/ASCZ49.1:

Minimum Protective Suggested

Arc Current Shade No. Shade No.

Less Than 300* 8 9

300 - 400* 9 12

400 - 800* 10 14

* These values apply where the actual arc is

clearly seen. Experience has shown that lighter

filters may be used when the arc is hidden by the

workpiece.
