The welding machine is suitable for MAG welding of carbon or mild steels using CO
shielding gas and Ar CO or Ar CO O mixtures Ar-Argon generally 80

flux core and tubular wire.
It is possible to use tubular wire without shielding gas self-shielding gas by adjusting
torch polarity according to the wire manufacturer's instructions.
For MAG welding of stainless steel, similar methods are use to those for carbon steel,
while it is necessary to use flux core or tubular wire identical to or compatible with the
base material and mixtures of Ar O or Ar CO shielding gas Ar generally 98
2
MIG welding of aluminium and its alloys should be carried out using wires with a
composition that is compatible with the material to be welded using pure Ar 99.9
shielding gas.
MIG brazing, typically, can be carried out on galvanised plate with copper alloy wires
e.g. copper-silicon or copper-aluminium with pure Ar 99.9

The most important data regarding use and performance of the welding machine are
summarised on the rating plate and have the following meaning:
1 Protection rating of the covering.
Symbol for power supply line:
1 : single phase alternating voltage;
3 : three phase alternating voltage.
Symbol : indicates that welding operations may be carried out in environments with
heightened risk of electric shock e.g. very close to large metallic volumes .
4 Symbol for welding procedure provided.
Symbol for internal structure of the welding machine.
EUROPEA standard of reference, for safety and construction of arc welding
machines.
Manufacturer's serial number for welding machine identification indispensable for
technical assistance, requesting spare parts, discovering product origin .
Performance of the welding circuit:
U
maximum no-load voltage open welding circuit .
0
U current and corresponding normalised voltage that the welding machine can
supply during welding.
Duty cycle: indicates the time for which the welding machine can supply the
corresponding current same column . It is expressed as
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 .
V V shows the range of adjustment for the welding current minimum
maximum at the corresponding arc voltage.
Technical specifications for power supply line:
U Alternating voltage and power supply frequency of welding machine allowed
1
limit 10 .
: Maximum current absorbed by the line.
1
: Effective current supplied.
1
10 : Size of delayed action fuses to be used to protect the power line.
11 Symbols referring to safety regulations, whose meaning is given in chapter 1
"General safety considerations for arc welding".
ote: 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.
