summarized below, deriving from welding operations.
For more detailed information, order the manual code
3.300.758
ELECTRIC AND MAGNETIC FIELDS - May be dangerous.
· Electric current following through any conductor causes localized Electric and Magnetic Fields (EMF). Welding/cutting current
creates EMF elds around cables and power sources.
· The magnetic elds created by high currents may affect
the operation of pacemakers. Wearers of vital electronic
equipment (pacemakers) should consult their physician
before beginning any arc welding, cutting, gouging or
spot welding operations.
· Exposure to EMF elds in welding/cutting may have
other health effects which are now not known.
· All operators should use the followingprocedures in or-
der to minimize exposure to EMF elds from the welding/
cutting circuit:
- Route the electrode and work cables together
- Secure them with tape when possible.
- Never coil the electrode/torch lead around your body.
- Do not place your body between the electrode/torch
lead and work cables. If the electrode/torch lead
cable is on your right side, the work cable should also
be on your right side.
- Connect the work cable to the workpiece as close as
possible to the area being welded/cut.
- Do not work next to welding/cutting power source.
EXPLOSIONS
· Do not weld in the vicinity of containers under
pressure, or in the presence of explosive dust,
gases or fumes. · All cylinders and pressure regulators used in welding operations should be handled with
care.

MANUEL D’INSTRUCTIONS POUR POSTE A SOUDER A FIL
IMPORTANT: AVANT LA MISE EN MARCHE DE LA MA-
CHINE, LIRE CE MANUEL ET LE GARDER, PENDANT
TOUTE LA VIE OPÉRATIONNELLE, DANS UN ENDROIT
CONNU PAR LES DIFFÉRENTES PERSONNES INTÉRESSÉES. CETTE MACHINE NE DOIT ÊTRE UTILISÉE
QUE POUR DES OPÉRATIONS DE SOUDURE.
1 PRÉCAUTIONS DE SÉCURITÉ
LA SOUDURE ET LE DÉCOUPAGE À L’ARC
PEUVENT ÊTRE NUISIBLES À VOUS ET AUX
AUTRES. L’utilisateur doit pourtant connaître les risques,
résumés ci-dessous, liés aux opérations de soudure. Pour
des informations plus détaillées, demander le manuel
code.3.300758
BRUIT
Cette machine ne produit pas elle-même des
bruits supérieurs à 80 dB. Le procédé de décou-
page au plasma/soudure peut produire des niveaux de bruit supérieurs à cette limite; les utilisateurs
devront donc mette en oeuvre les précautions prévues
par la loi.
CHAMPS ELECTROMAGNETIQUES- Peuvent être dangereux.
· Le courant électrique traversant n’importe
quel conducteur produit des champs électromagnétiques (EMF). Le courant de soudure ou de découpe produisent des champs
électromagnétiques autour des câbles ou
des générateurs.
• Les champs magnétiques provoqués par des courants
élevés peuvent interférer avec le fonctionnement des stimulateurs cardiaques.
C’est pourquoi, avant de s’approcher des opérations de
soudage à l’arc, découpe, décriquage ou soudage par
points, les porteurs d’appareils électroniques vitaux (stimulateurs cardiaques) doivent consulter leur médecin.
• L’ exposition aux champs électromagnétiques de soudure ou de découpe peut produire des effets inconnus
sur la santé.
Pour reduire les risques provoqués par l’exposition aux
champs électromagnétiques chaque opérateur doit
suivre les procédures suivantes:
- Vérier que le câble de masse et de la pince porte-
électrode ou de la torche restent disposés côte
à côte. Si possible, il faut les xer ensemble avec du
ruban.
- Ne pas enrouler les câbles de masse et de la pince
porte-électrode ou de la torche autour du corps.
- Ne jamais rester entre le câble de masse et le câble
de la pince porte-électrode ou de la torche. Si le
câble de masse se trouve à droite de l’opérateur,
le câble de la pince porte-électrode ou de la torche
doit être égale ment à droite.
- Connecter le câble de masse à la pièce à usiner
aussi proche que possible de la zone de soudure
ou de découpe.
- Ne pas travailler près du générateur.
EXPLOSIONS
· Ne pas souder à proximité de récipients sous
pression ou en présence de poussières, gaz ou
vapeurs explosifs. Manier avec soin les bouteilles
et les détendeurs de pression utilisés dans les opérations
de soudure.
COMPATIBILITE ELECTROMAGNETIQUE
Cette machine est construite en conformité aux indications contenues dans la norme harmonisée IEC 6097410(Cl. A) et ne doit être utilisée que pour des buts professionnels dans un milieu industriel. En fait, il peut y avoir
des difcultés potentielles dans l’assurance de la compatibilité électromagnétique dans un milieu différent de celui
industriel.
ÉLIMINATION D’ÉQUIPEMENTS ÉLECTRIQUES
ET ÉLECTRONIQUES
Ne pas éliminer les déchets d’équipements élec-
triques et électroniques avec les ordures ménagères! Une fois leur cycle de vie terminé, les équipements électriques et électroniques doivent être collectés
séparément et conférés à une usine de recyclage. Nous
recommandons aux propriétaires des équipements de
s’informer auprès de notre représentant local au sujet
des systèmes de collecte agréés.
EN CAS DE MAUVAIS FONCTIONNEMENT, DEMANDER
L’ASSISTANCE DE PERSONNEL QUALIFIÉ.
Des précautions supplémentaires sont à respecter
