mixes,
using tubular full or core electrode wires.
It is also ideal for MIG welding stainless steel with Argon gas cont 1-2%
oxygen and aluminium and CuSi3, CuAl8 (brazing) with Argon gas, using electrode
wires that are suitable for the workpiece to be welded.
It is particularly suitable for light metalwork fabrication and in body shops, for welding
galvanized plates, high stress stainless steel and aluminium. SYNERGIC operation
ensures fast and easy welding parameter setting, always guaranteeing high arc
control and welding quality.
The welding machine is designed for use with the SPOOL GUN torch, used to weld
aluminium and steel in the presence of wide spaces between the generator and the
piece to be welded (single torch version only).
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).

The most important data regarding use and performance of the welding machine are
summarised on the rating plate and have the following meaning:
)LJ$
EUROPEAN standard of reference, for safety and construction of arc welding
machines.
Symbol for internal structure of the welding machine.
Symbol for welding procedure provided.
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).
Symbol for power supply line:
1~ : single phase alternating voltage;
3~ : 3-phase alternating voltage.
Protection rating of the covering.
7HFKQLFDOVSHFL¿FDWLRQVIRUSRZHUVXSSO\OLQH
- U
: Alternating voltage and power supply frequency of welding machine (allowed
limit ±10%).
- I
PD[
: Maximum current absorbed by the line.
- I
HII
: effective current supplied.
Performance of the welding circuit:
- U : maximum no-load voltage (open welding circuit).
- I
8
: current and corresponding normalised voltage that the 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) are exceeded,
the thermal safeguard will trigger (the welding machine will remain in standby
until its temperature returns within the allowed limits).
-
$9$9
: shows the range of adjustment for the welding current (minimum
maximum) at the corresponding arc voltage.

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.
