électrique. Éloignez les bouteilles d’oxygène, les chaînes, les câbles métalliques, les appareils
de levage, les treuils et les élévateurs de toute partie du circuit électrique. Toutes les liaisons de
2 terre doivent être vérifiées périodiquement pour déterminer si elles sont solides et appropriées
SAFETY AND OPERATING INSTRUCTIONS
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.
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 porteélectrodes, 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.
RÉFÉRENCES EN MATIÈRE DE SÉCURITÉ ET D’UTILISATION
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.

SECTION 7: TROUBLESHOOTING
Contact tips and nozzles should be cleaned frequently. Spatter buildup may cause bridging
between nozzle and tip. This could cause electrical shorting between the nozzle and work
piece as well as poor or improper gas flow. Regularly inspect the conductor tube, handle,
cable, and other parts of the MIG Gun for abrasion, cuts, or undue wear. Replace or repair
any parts found deficient. Refer to www.Tweco.com for MIG Gun troubleshooting chart(s).
