ating area.

1.02 Important Safety Precautions

WARNING

OPERATION AND MAINTENANCE OF

PLASMA ARC EQUIPMENT CAN BE DAN-

GEROUS AND HAZARDOUS TO YOUR

HEALTH.

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 informa-

tion 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

circuit.

• Repair or replace all worn or damaged parts.

• Extra care must be taken when the workplace is

moist or damp.

• Install and maintain equipment according to NEC

code, refer to item 4 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.

GENERAL INFORMATION 2

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 recommended in Subsec-

tion 1.03, item 4.

FUMÉE et GAZ

La fumée et les gaz produits par le procédé de jet de

plasma peuvent présenter des risques et des dangers de

santé.

• Eloignez toute fumée et gaz de votre zone de respi-

ration. Gardez votre tête hors de la plume de fumée

provenant du chalumeau.

• Utilisez un appareil respiratoire à alimentation en

air si l’aération fournie ne permet pas d’éliminer la

fumée et les gaz.

• Les sortes de gaz et de fumée provenant de l’arc de

plasma dépendent du genre de métal utilisé, des

revêtements se trouvant sur le métal et des

différents procédés. Vous devez prendre soin

lorsque vous coupez ou soudez tout métal pouvant

contenir un ou plusieurs des éléments suivants:

antimoine cadmium mercure

argent chrome nickel

arsenic cobalt plomb

baryum cuivre sélénium

béryllium manganèse vanadium

• Lisez toujours les fiches de données sur la sécurité

des matières (sigle américain “MSDS”); celles-ci

devraient être fournies avec le matériel que vous

utilisez. Les MSDS contiennent des renseignements

quant à la quantité et la nature de la fumée et des

gaz pouvant poser des dangers de santé.

• Pour des informations sur la manière de tester la

fumée et les gaz de votre lieu de travail, consultez

l’article 1 et les documents cités à la page 5.

GENERAL INFORMATION 4

• Utilisez un équipement spécial tel que des tables de

coupe à débit d’eau ou à courant descendant pour

capter la fumée et les gaz.

• N’utilisez pas le chalumeau au jet de plasma dans

une zone où se trouvent des matières ou des gaz

combustibles ou explosifs.

• Le phosgène, un gaz toxique, est généré par la fumée

provenant des solvants et des produits de nettoyage

chlorés. Eliminez toute source de telle fumée.

CHOC ELECTRIQUE

Les chocs électriques peuvent blesser ou même tuer . Le

procédé au jet de plasma requiert et produit de l’énergie

électrique haute tension. Cette énergie électrique peut

produire des chocs graves, voire mortels, pour l’opérateur

et les autres personnes sur le lieu de travail.

• Ne touchez jamais une pièce “sous tension” ou

“vive”; portez des gants et des vêtements secs.

Isolez-vous de la pièce de travail ou des autres par-

ties du circuit de soudage.

• Réparez ou remplacez toute pièce usée ou

endommagée.

• Prenez des soins particuliers lorsque la zone de tra-

vail est humide ou moite.

• Montez et maintenez le matériel conformément au

Code électrique national des Etats-Unis. (Voir la

page 5, article 9.)

• Débranchez l’alimentation électrique avant tout tra-

vail d’entretien ou de réparation.

• Lisez et respectez toutes les consignes du Manuel

de consignes.

INCENDIE ET EXPLOSION

Les incendies et les explosions peuvent résulter des

scories chaudes, des étincelles ou de l’arc de plasma. Le

procédé à l’arc de plasma produit du métal, des étincelles,

des scories chaudes pouvant mettre le feu aux matières

combustibles ou provoquer l’explosion de fumées

inflammables.

• Soyez certain qu’aucune matière combustible ou in-

flammable ne se trouve sur le lieu de travail.

Protégez toute telle matière qu’il est impossible de

retirer de la zone de travail.

• Procurez une bonne aération de toutes les fumées

inflammables ou explosives.

• Ne coupez pas et ne soudez pas les conteneurs ayant

pu renfermer des matières combustibles.

• Prévoyez une veille d’incendie lors de tout travail

dans une zone présentant des dangers d’incendie.

• Le gas hydrogène peut se former ou s’accumuler

sous les pièces de travail en aluminium lorsqu’elles

sont coupées sous l’eau ou sur une table d’eau. NE

PAS couper les alliages en aluminium sous l’eau

ou sur une table d’eau à moins que le gas hydrogène

peut s’échapper ou se dissiper. Le gas hydrogène

accumulé explosera si enflammé.

RAYONS D’ARC DE PLASMA

Les rayons provenant de l’arc de plasma peuvent blesser

vos yeux et brûler votre peau. Le procédé à l’arc de plasma

produit une lumière infra-rouge et des rayons ultra-vio-

lets très forts. Ces rayons d’arc nuiront à vos yeux et

brûleront votre peau si vous ne vous protégez pas

correctement.

• Pour protéger vos yeux, portez toujours un casque

ou un écran de soudeur. Portez toujours des lunettes

de sécurité munies de parois latérales ou des lu-

nettes de protection ou une autre sorte de protec-

tion oculaire.

• Portez des gants de soudeur et un vêtement

protecteur approprié pour protéger votre peau

contre les étincelles et les rayons de l’arc.

• Maintenez votre casque et vos lunettes de protec-

tion en bon état. Remplacez toute lentille sale ou

comportant fissure ou rognure.

• Protégez les autres personnes se trouvant sur la zone

de travail contre les rayons de l’arc en fournissant

des cabines ou des écrans de protection.

• Respectez le teint de lentille recommandé dans le

article 4, page 5.

BRUIT

Le bruit peut provoquer une perte permanente de l’ouïe.

Les procédés de soudage à l’arc de plasma peuvent

provoquer des niveaux sonores supérieurs aux limites

normalement acceptables. V ous dú4ez vous protéger les

oreilles contre les bruits forts afin d’éviter une perte

permanente de l’ouïe.

• Pour protéger votre ouïe contre les bruits forts, portez

des tampons protecteurs et/ou des protections

auriculaires. Protégez également les autres

personnes se trouvant sur le lieu de travail.

• Il faut mesurer les niveaux sonores afin d’assurer

que les décibels (le bruit) ne dépassent pas les

niveaux sûrs.

5 GENERAL INFORMATION

Choosing a Location

CAUTION

NOTE

3.02 CHOOSING A LOCATION

Select a clean, dry location with good ventilation and adequate

working space around all components.

The power supply is cooled by air flow through the rear panel.

Air flow must not be obstructed. Provide at least 2 feet (0.61 m) of

clearance in the rear. Provide at least 6 inches (0.15 m) clearance

on each side. Provide sufficient clearance in front of the unit to

allow access to front panel controls (minimum 6 in or 0.15 m).

Operation without proper air flow will inhibit proper cooling and

reduce duty cycle.

Review Important Safety Precautions at the front of this Manual

to be sure that the selected location meets all safety requirements.

Disconnect primary power at the source before disassembling

the power supply, torch, or torch leads.

The torch parts (shield cup, tip, electrode, and gas distributor)

must correspond with the type of operation (drag cutting, stand-

off cutting, or gouging). Refer to Torch Parts Selection (page 31).

The torch is factory assembled with the control switch in the top

front position (see Figure 3-A below). To position the control

switch on the bottom (underside) of the handle, pull the handle

back approximately 2 inches (51 mm) and rotate the handle

assembly 180° (do not rotate beyond 180°). To position the

control switch in the rear position:

1. Locate the tab on the back of the switch track closure. Gently

press in on the tab and carefully pry the closure upward.

2. Remove the switch track insert and the torch control switch.

3. Reinstall the switch track insert, then the switch, then the

switch track closure.
