- L'interrupteur général étant sur "ON", le témoin relatif est
allumé; dans le cas contraire la panne réside
normalement dans la ligne d'alimentation (câbles, prise
et/ou fiche, fusibles, etc.).
- Vérifier que le voyant lumineux jaune signalant
l'intervention de la sécurité thermique contrôlant les
surtensions, les chutes de tension ou les courts-circuits
n'est pas allumé.
- S'assurer d'avoir observé le rapport d'intermittence
nominale. En cas d'intervention de la protection
thermostatique attendre le refroidissement naturel de la
machine. Vérifier le bon fonctionnement du ventilateur.
- Contrôler la tension de ligne : une valeur trop élevée ou
trop basse entraîne le blocage du poste de soudage.
- Contrôler qu'il n'y a pas un court-circuit en sortie de
machine. Si tel est le cas, procéder à l'élimination de
l'inconvénient.
- Les raccords du circuit de soudage soient correctement
effectués, spécialement que la pince du câble de masse
soit effectivement reliée à la pièce, sans interposition de
matériaux isolants (ex. des peintures).
- Que le gaz de protection utilisé soit correct (Argon
99,5%) et dans la juste quantité.

INSTRUCTION MANUAL
WARNING! BEFORE USING THE WELDING MACHINE
READ THE INSTRUCTION MANUAL CAREFULLY .
ARC WELDING MACHINES FOR COA TED ELECTRODES
(MMA) FOR INDUSTRIAL AND PROFESSIONAL USE.
Note: In the following text the term "welding machine" will be
used.
1. GENERAL SAFETY
CONSIDERATIONS FOR ARC
WELDING
The operator should be properly trained to use the
welding machine safely and should be informed about
the risks related to arc welding procedures, the
associated protection measures and emergency
procedures.
(Refer also to the "IEC TECHNICAL SPECIFICATION or
CLC/TS 62081": INSTALLATION AND USE OF
EQUIPMENT FOR ARC WELDING).
- Avoid direct contact with the welding circuit: the no-
load voltage supplied by the welding machine can be
dangerous under certain circumstances.
- When the welding cables are being connected or
checks and repairs are carried out the welding
machine should be switched off and disconnected
from the power supply outlet.
- Switch off the welding machine and disconnect it
from the power supply outlet before replacing
consumable torch parts.
- Make the electrical connections and installation
according to the safety rules and legislation in force.
- The welding machine should be connected only and
exclusively to a power source with the neutral lead
connected to earth.
- Make sure that the power supply plug is correctly
connected to the earth protection outlet.
- Do not use the welding machine in damp or wet
places and do not weld in the rain.
- Do not use cables with worn insulation or loose
connections.
- Do not weld on containers or piping that contains or
has contained flammable liquid or gaseous
products.
- Do not operate on materials cleaned with chlorinated
solvents or near such substances.
- Do not weld on containers under pressure.
- Remove all flammable materials (e.g. wood, paper,
rags etc.) from the working area.
- Provide adequate ventilation or facilities for the
removal of welding fumes near the arc; a systematic
approach is needed in evaluating the exposure limits
for the welding fumes, which will depend on their
composition, concentration and the length of
exposure itself.
- Keep the gas bottle (if used) away from heat sources,
including direct sunlight.
- Use adequate electrical insulation with regard to the
electrode, the work piece and any (accessible)
earthed metal parts in the vicinity.
This is normally achieved by wearing gloves, shoes,
head coverings and clothing designed for this
purpose and by using insulating platforms or mats.
- Always protect your eyes using masks or helmets
with special actinic glass.
Use special fire-resistant protective clothing and do
not allow the skin to be exposed to the ultraviolet and
infrared rays produced by the arc; other people in the
vicinity of the arc should be protected by shields of
non-reflecting curtains.
- The electromagnetic fields generated by the welding
process may interfere with the operation of electrical
and electronic equipment.
Users of vital electrical or electronic devices (e.g.
pace-makers, respirators etc.) should consult a
doctor before stopping in the vicinity of areas where
this welding machine is used.
Users of vital electrical or electronic devices should
not use the welding machine.
- This welding machine complies with the
requirements of the technical standard for the
product for use only and exclusively in industrial
environments and for professional purposes. It is not
guaranteed to meet electromagnetic compatibility
requirements in the home.
EXTRA PRECAUTIONS
- WELDING OPERATIONS:
- In environments with increased risk of electric
shock
- In confined spaces
- In the presence of flammable or explosive materials
MUST BE evaluated in advance by an "Expert
supervisor" and must always be carried out in the
presence of other people trained to intervene in
