WARNING! BEFORE USING THE WELDING MACHINE
READ THE INSTRUCTION MANUAL CAREFULLY
ARC WELDING MACHINES FOR COATED 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
emergencies.
Technical protection measures MUST BE taken as
described in 5.10; A.7; A.9. of the "IEC TECHNICAL
SPECIFICATION or CLC/TS 62081".
- The operator MUST NOT BE ALLOWED to weld in
raised positions unless safety platforms are used.
- VOLTAGE BETWEEN ELECTRODE HOLDERS OR
TORCHES: working with more than one welding
machine on a single piece or on pieces that are
connected electrically may generate a dangerous
accumulation of no-load voltage between two
different electrode holders or torches, the value of
which may reach double the allowed limit.
An expert coordinator must use measuring
instruments to determine the existence of a risk and
should take suitable protection measures as detailed
in 5.9 of the "IEC TECHNICAL SPECIFICATION or
CLC/TS 62081".

RESIDUAL RISKS

- OVERTURNING: position the welding machine on a
horizontal surface that is able to support the weight:
otherwise (e.g. inclined or uneven floors etc.) there is
danger of overturning.
- IMPROPER USE: it is hazardous to use the welding
machine for any work other than that for which it was
designed (e.g. de-icing mains water pipes).
- Never lift the welding machine until the gas bottle,
wire feeder and all power and interconnecting
cables/pipes have been disconnected (if present).
The only permitted lifting method is that described in
the "INSTALLATION" section of this manual.
