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

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.

GASES AND FUMES

Gases and fumes produced during the plasma cutting

process can be dangerous and hazardous to your health.

• Keep all fumes and gases from the breathing area.

Keep your head out of the welding fume plume.

• Use an air-supplied respirator if ventilation is not

adequate to remove all fumes and gases.

• The kinds of fumes and gases from the plasma arc

depend on the kind of metal being used, coatings

on the metal, and the different processes. You must

be very careful when cutting or welding any met-

als which may contain one or more of the follow-

ing:

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 information

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.

ELECTRIC SHOCK

Electric Shock can injure or kill. The plasma arc process

uses and produces high voltage electrical energy. This

electric energy can cause severe or fatal shock to the op-

erator or others in the workplace.

• Never touch any parts that are electrically “live” or

“hot.”

• Wear dry gloves and clothing. Insulate yourself from

the work piece or other parts of the welding cir-

cuit.

• Repair or replace all worn or damaged parts.

• Extra care must be taken when the workplace is

moist or damp.

GENERAL INFORMATION 2 Date 6/22/99

• Install and maintain equipment according to NEC

code, refer to item 9 in Subsection 1.03, Publica-

tions.

• Disconnect power source before performing any ser-

vice or repairs.

• Read and follow all the instructions in the Operat-

ing Manual.

FIRE AND EXPLOSION

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

the plasma arc.

• Be sure there is no combustible or flammable mate-

rial in the workplace. Any material that cannot be

removed must be protected.

• Ventilate all flammable or explosive vapors from

the workplace.

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

combustibles.

• Provide a fire watch when working in an area where

fire hazards may exist.

• Hydrogen gas may be formed and trapped under

aluminum workpieces when they are cut under-

water or while using a water table. DO NOT cut

aluminum alloys underwater or on a water table

unless the hydrogen gas can be eliminated or dis-

sipated. Trapped hydrogen gas that is ignited will

cause an explosion.

NOISE

Noise can cause permanent hearing loss. Plasma arc pro-

cesses can cause noise levels to exceed safe limits. You

must protect your ears from loud noise to prevent per-

manent loss of hearing.

• To protect your hearing from loud noise, wear pro-

tective ear plugs and/or ear muffs. Protect others

in the workplace.

• Noise levels should be measured to be sure the deci-

bels (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.

PLASMA ARC RAYS

Plasma Arc Rays can injure your eyes and burn your skin.

The plasma arc process produces very bright ultra violet

and infra red light. These arc rays will damage your

eyes and burn your skin if you are not properly protected.

• To protect your eyes, always wear a welding hel-

met or shield. Also always wear safety glasses with

side shields, goggles or other protective eye wear.

• Wear welding gloves and suitable clothing to pro-

tect your skin from the arc rays and sparks.

• Keep helmet and safety glasses in good condition.

Replace 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/ASC Z49.1:

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 work-

piece.
