- 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).
- IMPROPER USE: the use the welding machine by more than one
operator at the same time may be dangerous.
- MOVING THE WELDING MACHINE: Always secure the gas bottle,
taking suitable precautions so that it cannot fall accidentally (if
used).
- Do not use the handle to hang the welding machine.
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.
2. INTRODUCTION AND GENERAL DESCRIPTION
This welding machine is a source of current for arc welding, made
specifically for MAG welding carbon steel or weak alloys with CO
protective gas or Argon/CO
mixes, using full or core electrode wires.
2
It is also ideal for MIG welding stainless steel with Argon gas containing
+ 1-2% oxygen and aluminium and CuSi (brazing) with Argon gas, using
electrode wires that are suitable for the workpiece to be welded.
Suitable core wires can also be used without Flux protection gas, adapting
torch polarity according to the indications of the wire producer.
It is particularly suitable for light metalwork fabrication and in body shops,
for welding galvanized plates, high stress stainless steel and aluminium.
MULTIPROCESS VERSION:
The welding machine can be used for TIG welding in direct current (DC),
with arc striking upon contact (LIFT ARC mode). It welds all types of steel
(carbon, low- and high-alloy) and heavy metals (copper, nickel, titanium
and their alloys) with a gas shield of pure (99.9%) Ar or, for special uses,
with an Argon/Helium mix. It can also be used for MMA electrode welding
in direct current (DC) using coated electrodes (rutile, acid, basic).

3. TECHNICAL DATA
DATA PLATE
The most important data regarding use and performance of the welding
machine are summarised on the rating plate and have the following
meaning:
1- EUROPEAN standard of reference, for safety and construction of arc
welding machines.
2- Symbol for internal structure of the welding machine.
3- Symbol for welding procedure provided.
4- Symbol S: indicates that welding operations may be carried out in
environments with heightened risk of electric shock (e.g. very close
to large metallic volumes).
5- Symbol for power supply line:
1~ : single phase alternating voltage;
3~ : 3-phase alternating voltage.
6- Protection rating of the covering.
7- Technical specifications for power supply line:
- U
: Alternating voltage and power supply frequency of welding
1
machine (allowed limit ±10%).
- I
: Maximum current absorbed by the line.
1 max
- I
: effective current supplied.
1eff
8- Performance of the welding circuit:
- U
: maximum no-load voltage (open welding circuit).
0
- I
/U
: current and corresponding normalised voltage that the
2
2
welding machine can supply during welding.
- X : Duty cycle: indicates the time for which the welding machine
can supply the corresponding current (same column). It is
expressed as %, based on a 10 min. cycle (e.g. 60% = 6 minutes
working, 4 minutes pause, and so on).
If the usage factors (on the plate, referring to a 40°C environment)
2
are exceeded, the thermal safeguard will trigger (the welding
machine will remain in standby until its temperature returns within
the allowed limits).
- A/V-A/V : shows the range of adjustment for the welding current
(minimum maximum) at the corresponding arc voltage.
9- Manufacturer's serial number for welding machine identification
(indispensable for technical assistance, requesting spare parts,
discovering product origin).
: Size of delayed action fuses to be used to protect the
10-
power line.
11- Symbols referring to safety regulations, whose meaning is given in
chapter 1 "General safety considerations for arc welding".
Note: The data plate shown above is an example to give the meaning
of the symbols and numbers; the exact values of technical data for the
welding machine in your possession must be checked directly on the data
plate of the welding machine itself.
