de levage, les treuils et les élévateurs de toute partie du circuit électrique. Toutes les liaisons de

terre doivent être vériﬁées périodiquement pour déterminer si elles sont solides et appropriées

SAFETY AND OPERATING INSTRUCTIONS

389200016

cylinders, chains, wires, ropes, cranes, and hoists away from any part of the electrical path.

All ground connections must be checked periodically to determine if they are mechanically

strong, and electrically adequate for the required current. When engaged in AC welding/

cutting under wet conditions or where perspiration is a factor, the use of automatic controls

for reducing the no load voltage is recommended to reduce shock hazards. Accidental contact

must be prevented when using open circuit voltage exceeding 80 volts AC, or 100 volts DC by

adequate insulation or other means. When welding is to be suspended for any length of time,

such as during lunch or overnight, all electrode holders and electrodes should be removed

from the electrode holder and the power supply should be turned off to prevent accidental

contact. Keep MIG Guns, electrode holders, TIG torches, Plasma torches, and electrodes away

from moisture and water.

SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH

Ventilation must be adequate to remove smoke, fumes, and gases during

operation to protect operators and others in the area. Vapors of chlorinated

solvents can form the toxic gas “Phosgene” when exposed to ultraviolet

radiation from an electric arc. All solvents, degreasers, and potential

sources of these vapors must be removed from the operating area. Use

air-supplied respirators if ventilation is not adequate to remove all fumes and gases. Oxygen

supports, and vigorously accelerates ﬁre and should never be used for ventilation.

ARC RAYS, HOT SLAG, AND SPARKS CAN INJURE EYES AND BURN SKIN

Welding and cutting processes produce extreme localized heat and strong

ultraviolet rays. Never attempt to weld/cut without a federally compliant

welding helmet with the proper lens. A number 12 to 14 shade ﬁlter lens

provides the best protection against arc radiation. When in a conﬁned area,

prevent the reﬂected arc rays from entering around the helmet. Approved

shielding curtains and appropriate goggles should be used to provide protection to others in

the surrounding area. Skin should be protected from arc rays, heat, and molten metal. Always

wear protective gloves and clothing. All pockets should be closed and cuffs sewn shut.

Leather aprons, sleeves, leggings, etc. should be worn for out-of-position welding and cutting,

or for heavy operations using large electrodes. Hightop work shoes provide adequate

protection from foot burns. For added protection, use leather spats. Flammable hair

preparations should not be used when welding/cutting. Wear ear plugs to protect ears from

sparks. Where work permits, the operator should be enclosed in an individual booth painted

with a low reﬂective material such as zinc oxide.

WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS

Combustibles reached by the arc, ﬂame, ﬂying sparks, hot slag, and heated

materials can cause ﬁre and explosions. Remove combustibles from the

work area and/or provide a ﬁre watch. Avoid oily or greasy clothing as a

spark may ignite them. Have a ﬁre extinguisher nearby, and know how to

use it. If welding/cutting is to be done on a metal wall, partition, ceiling, or

roof, precautions must be taken to prevent ignition of nearby combustibles

on the other side. Do not weld/cut containers that have held combustibles. All hollow spaces,

cavities, and containers should be vented prior to welding/cutting to permit the escape of air

or gases. Purging with inert gas is recommended. Never use oxygen in a welding torch. Use

only inert gases or inert gas mixes as required by the process. Use of combustible

compressed gases can cause explosions resulting in personal injury or death. Arcing against

any compressed gas cylinder can cause cylinder damage or explosion.

NOISE CAN DAMAGE HEARING

Noise from the air carbon-arc process can damage your hearing. Wear

protective hearing devices to ensure protection when noise levels exceed

OHSA standards. Adequate hearing protection devices must be worn by

operators and surrounding personnel to ensure personal protection against

noise.

au courant demandé. En cas de soudage ou de découpage en courant alternatif dans des

conditions d’humidité ou de chaleur où l’opérateur risque de transpirer, il est recommandé

d’utiliser des contrôles automatiques pour réduire la tension à vide et ainsi diminuer les

risques de choc électrique. Lorsque le procédé de soudage et de découpage exige des valeurs

de tension en circuit ouvert dans des machines à courant alternatif supérieur à 80 volts ou

dans des machines à courant continu supérieur à 100 volts, il faut prendre des mesures pour

empêcher un contact accidentel en prévoyant une isolation adéquate ou d autres moyens.

Lorsqu’il faut interrompre les activités de soudage pendant un certain temps, à l’heure du repas

ou la nuit, par exemple, il faut enlever toutes les électrodes du porte-électrode et mettre hors

tension l’alimentation pour éviter tout contact accidentel. Gardez les pistolets MIG, les porte-

électrodes, les torches TIG, les torches à plasma et les électrodes loin de l’humidité et de l’eau.

LA FUMÉE, LES ÉMANATIONS ET LES GAZ PEUVENT ÊTRE DANGEREUX POUR VOTRE SANTÉ

La ventilation doit être sufﬁsante pour enlever la fumée, les émanations et les

gaz pendant le fonctionnement de la torche aﬁn protéger les opérateurs et les

autres personnes présentes dans la zone. Les vapeurs de solvants chlorés

peuvent former un gaz toxique appelé « Phosgène » si elles sont exposées au

rayonnement ultraviolet d un arc électrique. Il faut enlever de la zone de travail

tous les solvants, décapants et sources potentielles de ces vapeurs. Servez-vous d’appareils

respiratoires à adduction d’air si la ventilation n’est pas sufﬁsante pour enlever toutes les

émanations et gaz. L’oxygène alimente les incendies et en accélère la propagation il ne faut

jamais l’utiliser à des ﬁns de ventilation.

L LES RAYONS DE L’ARC, LES SCORIES ET LES ÉTINCELLES CHAUDS PEUVENT BLESSER

LES YEUX ET BRÛLER LA PEAU

Les procédés de soudage et de découpage produisent une chaleur extrême

localisée et de puissants rayons ultraviolets. N’essayez jamais de souder ou de

couper sans casque soudage conforme aux normes du gouvernement fédéral et

muni d’une lentille appropriée. Des lentilles à ﬁltre de numéro 12 à 14

fournissent la meilleure protection contre le rayonnement de l’arc. Dans un endroit conﬁné, il

faut éviter que les rayons reﬂétés de l’arc n’entrent autour du casque. Il faut utiliser des rideaux

de protection approuvés et des lunettes de protection appropriées pour protéger les autres

personnes se trouvant aux abords. Il faut aussi protéger la peau nue des rayons de l’arc, de la

chaleur et du métal fondu. Portez toujours des gants et des vêtements de protection. Toutes les

poches doivent être fermées et les manchettes, cousues. Il faut porter un tablier, des manches,

des guêtres, etc. en cuir pour effectuer de soudage ou de découpage et dans le cas des activités

intensives nécessitant de grandes électrodes. Les chaussures de sécurité montantes fournissent

une protection sufﬁsante contre les brûlures aux pieds. Pour obtenir une plus grande protection,

portez des guêtres en cuir. Il ne faut pas utiliser de produits capillaires inﬂammables avant

d’effectuer des activités de soudage ou de découpage. Portez des bouchons d’oreilles pour vous

protéger les oreilles des étincelles. Lorsqu’il est possible de le faire dans la zone de travail,

l’opérateur doit s’isoler dans une cabine individuelle recouverte d’un revêtement à faible

réﬂectivité, comme l’oxyde de zinc.

LES ÉTINCELLES DE SOUDAGE PEUVENT CAUSER DES INCENDIES ET DES EXPLOSIONS

Les combustibles atteints par l’arc, les ﬂammes, les vols d’étincelles, les

scories chaudes et les matériaux chauffés peuvent causer des incendies et des

explosions. Enlevez les combustibles de la zone de travail ou mettez en place du

personnel de surveillance. Évitez les vêtements huileux ou graisseux, car une

étincelle peut y mettre le feu. Ayez un extincteur à proximité et sachez comment

l’utiliser. Si l’activité de soudage ou de découpage doit être fait contre un mur, une cloison, un

plafond ou un toit, il faut prendre des précautions pour d’enﬂammer des combustibles qui se

trouveraient à proximité, de l’autre côté. Ne soudez pas et ne coupez pas de conteneurs ayant

contenu des combustibles. Il faut aérer tous les espaces creux, les cavités et les conteneurs

avant de les soumettre au soudage ou au découpage aﬁn d’évacuer tout l’air ou le gaz qui peut

s’y trouver. Il est recommandé d’effectuer une purge avec du gaz inerte. N’utilisez jamais

d’oxygène dans une tête de soudage. N’utilisez que des gaz inertes ou des mélanges de gaz

inertes, conformément aux exigences du procédé. L’utilisation de gaz combustibles comprimés

peut causer des explosions entraînant des blessures ou la mort. Le fait d’utiliser l’arc sur une

bouteille de gaz comprimé peut endommager la bouteille ou causer une explosion.

LE BRUIT PEUT ENDOMMAGER L’OUÏE

Le bruit du procédé de l’arc avec électrode en carbone et jet d’air peut

endommager l’ouïe. Portez un dispositif de protection de l’ouïe pour vous

protéger lorsque le niveau de bruit dépasse les normes de l’OSHA. Les

opérateurs et le personnel aux abords doivent porter un dispositif de protection

de l’ouïe approprié pour les protéger efﬁcacement contre le bruit.
