1. INTRODUCTION

1.1 Notes, Cautions and Warnings

Throughout this manual, notes, cautions, and warnings are used to highlight important

information. These highlights are categorized as follows:

NOTE

An operation, procedure, or background information which requires additional emphasis or is helpful 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 operating area.

1.2 Important Safety Precautions

WARNING

OPERATION AND MAINTENANCE OF WELDING ARC EQUIPMENT CAN BE DANGEROUS

AND HAZARDOUS TO YOUR HEALTH.

To prevent possible injury, read, understand and follow all warnings, safety precautions and instructions

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 welding 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 welding 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 metals which may contain one or more of the following:

Antimony Beryllium Cobalt Manganese Selenium

Arsenic Cadmium Copper Mercury Silver

Barium Chromium Lead Nickel Vanadium

•Always read the Material Safety Data Sheets (MSD’s) that should be supplied with the material

you are using. These MSDS’s 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 1.3, Publications in this manual.

•Use special equipment, such as water or down draft cutting tables, to capture fumes and gases.

•Do not use the welding torch in an area where combustible 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.

Viking 210GM, 250GM

ELECTRIC SHOCK

Electric Shock can injure or kill. The welding arc process uses and produces high voltage

electrical energy. This electric energy can cause severe or fatal shock to the operator 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 1.3,

Publications.

•Disconnect power source before performing any service or repairs.

•Read and follow all the instructions in the Operating Manual.

FIRE AND EXPLOSION

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

•Be sure there is no combustible or flammable material 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.

NOISE

Noise can cause permanent hearing 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 hearing.

•To protect your hearing from loud noise, wear protective ear plugs and/or ear muffs. Protect

others in the workplace.

•Noise levels should be measured to be sure the decibels (sound) do not exceed safe levels.

•For information on how to test for noise, see item 1 in Subsection 1.3, Publications, in this

manual.

ARC RAYS

Arc Rays can injure your eyes and burn your skin. The welding 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 helmet or shield. Also always wear safety glasses

with side shields, 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. 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 the Operating Manual.

Dans ce manuel, les mots “note,” “attention,” et “avertissement” sont utilisés pour mettre en relief

des informations à caractère important. Ces mises en relief sont classifiées comme suit :

NOTE

Toute opération, procédure ou renseignement général sur lequel il importe d’insister davantage ou qui

contribue à l’efficacité de fonctionnement du système.

ATTENTION

Toute procédure pouvant résulter l’endommagement du matériel en cas de non-respect de la procédure en

question.

AVERTISSEMENT

Toute procédure pouvant provoquer des blessures de l’opérateur ou des autres personnes se trouvant dans la

zone de travail en cas de non-respect de la procédure en question.

1.5 Precautions De Securite Importantes

AVERTISSEMENT

L’OPÉRATION ET LA MAINTENANCE DU MATÉRIEL DE SOUDAGE À L’ARC AU JET DE

PLASMA PEUVENT PRÉSENTER DES RISQUES ET DES DANGERS DE SANTÉ.

Il faut communiquer aux opérateurs et au personnel TOUS les dangers possibles. Afin d’éviter les blessures

possibles, lisez, comprenez et suivez tous les avertissements, toutes les précautions de sécurité et toutes les

consignes avant d’utiliser le matériel. Composez le + 603-298-5711 ou votre distributeur local si vous avez

des questions.

Viking 210GM, 250GM

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 respiration. 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 soudage 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 baryum chrome manganèse plomb

argent béryllium cobalt mercure sélénium

arsenic cadmium cuivre nickel 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 7

•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 soudage 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 soudage 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 travail est humide ou moite.

•Montez et maintenez le matériel conformément au Code électrique national des Etats-Unis.

(Voir la page v, article 9.)

•Débranchez l’alimentation électrique avant tout travail d’entretien ou de réparation.

•Lisez et respectez toutes les consignes du Manuel de consignes.
