WARNING! BEFORE USING THE WELDING MACHINE READ
THE INSTRUCTION MANUAL CAREFULLY.
CONTINUOUS WIRE WELDING MACHINE FOR MIG/MAG-FLUX,
TIG, MMA ARC WELDING DESIGNED 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 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.
-
Noise level: If particularly intensive welding operations cause
a personal daily exposure level (LEPd) that is greater than or
equal to 85db(A), the use of suitable personal protectors is
compulsory.
-
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 elec
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".
- Welding MUST NOT be allowed if the welding machine or wire
feeder is supported by the operator (e.g. using belts).
- 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).
-
MOVING THE WELDING MACHINE: always secure the gas
bottle, taking suitable precautions so that it cannot fall
accidentally.
The safety guards and moving parts of the covering of the
welding machine and of the wire feeder should be in their proper
positions before connecting the welding machine to the power
supply.
WARNING! Any manual operation carried out on the moving parts
of the wire feeder, for example:
- Replacing rollers and/or the wire guide;
- Inserting wire in the rollers;
- Loading the wire reel;
- Cleaning the rollers, the gears and the area underneath them
- Lubricating the gears
SHOULD BE CARRIED OUT WITH THE WELDING MACHINE
SWITCHED OFF AND DISCONNECTED FROM THE POWER
SUPPLY OUTLET.

INTRODUCTION
These single phase welding machines are power sources based on
state-of-the-art IGBT inverter technology with completely digital
control, and are equipped with an integrated wire feeder.
The welding machines can be used for high quality welding in
continuous synergic MIG/MAG, TIG and MMA and in pulsed synergic
MIG/MAG when included.
The wire feeder is equipped with a 2-roller motorised wire puller unit
with independent adjustment of pulling pressure. The digital control
panel is integrated with the microprocessor adjustment board and it
contains fundamentally three condensed functions:
