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 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.)

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.”

GENERAL INFORMATION 1-2 Date: January 27, 2004

• 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 9 in Subsection 1.03, Publica-

tions.

• Disconnect power source before performing any

service 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 ma-

terial 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.

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.

GENERAL INFORMATION 1-4 Date: January 27, 2004

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

tion. 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.

• 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 combus-

tibles 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.

• Ce produit, dans le procéder de soudage et de coupe,

produit de la fumée ou des gaz pouvant contenir des

éléments reconnu dans L’état de la Californie, qui

peuvent causer des défauts de naissance et le cancer.

(La sécurité de santé en Californie et la code sécurité

Sec. 25249.5 et seq.)

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 parties 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 com-

bustibles 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

Date: January 27, 2004 1-5 GENERAL INFORMATION

ultra-violets 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 lunettes de

protection ou une autre sorte de protection 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 protection

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

Firepower PC-500 Power Supply Duty Cycle *

Power Supply includes input cable with plug.

* NOTE: The duty cycle will be reduced if the primary input power (AC) is low

or the output voltage (DC) is higher than shown in this chart.

NOTE:

IEC Rating is determined as specified by the International Electro-Technical Commission. These specifications in-

clude calculating an output voltage based upon power supply rated current. To facilitate comparison between power

supplies, all manufacturers use this output voltage to determine duty cycle.

TDC Rating is determined using an output voltage representative of actual output voltage during cutting with a TDC

torch. This voltage may be more or less than IEC voltage, depending upon choice of torch, consumables, and actual

cutting operation.
