SECTION 1: SAFETY PRECAUTIONS

WARNING

SERIOUS INJURY OR DEATH may result if welding and cutting equipment is not
properly installed, used, and maintained. Misuse of this equipment and other
unsafe practices can be hazardous. The operator, supervisor, and helper must read
and understand the following safety warnings and instructions before installing
or using any welding or cutting equipment, and be aware of the dangers of the
welding or cutting process. Training and proper supervision are important for a safe
work place. Keep these instructions for future use. Additional recommended safety
and operating information is referenced in each section.

ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH

Install and maintain equipment in accordance with the National Electrical Code
(NFPA 70) and local codes. Do not service or repair equipment with power on.
Do not operate equipment with protective insulators or covers removed. Service
or repair to equipment must be done by qualified and/or trained personnel only.

Do not contact electrically live parts. Always wear dry welding gloves that
are in good condition. Aluminized, protective clothing can become part of the electrical path.
Keep oxygen 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.

MESURES DE SÉCURITÉ

AVERTISSEMENT

DES BLESSURES GRAVES OU MORTELLES peuvent résulter d’une installation,
d’un usage ou d’un entretien inadéquat de l’équipement de soudage et de décou­page. Une mauvaise utilisation de cet équipement et d’autres pratiques risquées
peuvent être dangereuses. L’opérateur, le superviseur et l’aide doivent lire et com­prendre les avertissements et les instructions de sécurité suivantes avant d’installer
ou d’utiliser tout équipement de soudage ou de découpage et être conscients des
dangers inhérents aux processus de soudage et de découpage. Une formation et
une supervision adaptées sont importantes pour assurer un lieu de travail sûr.
Gardez ces instructions pour une utilisation future. Chaque section comporte des
informations supplémentaires de sécurité et de fonctionnement.

UN CHOC ÉLECTRIQUE PEUT CAUSER DES BLESSURES OU LA MORT

L’installation et l’entretien de l’équipement doivent être conformes au Code national
de l’électricité NFPA 70 et aux codes locaux. N’effectuez pas l’entretien ou la
réparation d’équipement en marche. N’opérez pas l’équipement sans isolateurs ou
caches de protection. L’entretien ou la réparation de l’équipement doivent être
effectués uniquement par un technicien qualifié ou par du personnel formé.

Ne touchez pas aux pièces électriques chargées. Portez toujours des gants de soudage au sec
et en bon état. Les vêtements de protection aluminisés peuvent devenir une partie du chemin
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
terre doivent être vérifiées périodiquement pour déterminer si elles sont solides et appropriées 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
