Explanation of the technical specifications listed on the machine plate
This machine is manufactured according to the following international standards: IEC 60974.1 - IEC 60974.3 -IEC
60974.10 CL. A - IEC 61000-3-12 - IEC 61000-3-11 (see note 2).
N°.
Serial number, which must be indicated on any type of request regarding the welding machine.
Single-phase static transformer-rectifierfrequency converter.
Drooping characteristic.
SMAW
Suitable for welding with covered electrodes.
TIG
Suitable for TIG welding.
U0.
Secondary open-circuit voltage X.Duty cycle percentage. % of 10 minutes during which the welding ma-
chine may run at a certain current without overheating.
I2
Welding current
U2.
Secondary voltage with current I2
U1.
Rated supply voltage
3~ 50/60Hz 50- or 60-Hz three-phase power supply
I1 max.
This is the maximum value of the absorbed current.
I1 eff.
This is the maximum value of the actual current absorbed, considering the duty cycle.
IP23S
Protection rating for the housing.
Grade 3 as the second digit means that this equipment may be stored, but it is not suitable for use outdoors
in the rain, unless it is protected.
S
Suitable for hazardous environments.
Note:
1-
The machine has also been designed for use in environments with a pollution rating of 1. (See IEC 60664).
2-
This equipment complies with IEC 61000-3-12 provided that the maximum permissible system impedance
Zmax is less than or equal to 0,137 (art.514) - 0,081 (art.519) at the interface point between the user's supply and the
public system. It is the responsibility of the installer or user of the equipment to ensure, by consultation with the dis-
tribution network operator if necessary, that the equipment is connected only to a supply with maximum permissible
system impedance Zmax less than or equal to 0,137 (art.514) - 0,081 (art.519)

Description of protective devices
2�3�1
Thermal protection
This equipment is protected by a thermostat. When the thermostat is tripped, the machine stops delivering current but
the fan continues to run. The yellow led (B) lights to indicate when it is tripped. Do not shut off the welding machine
until the led has gone off.
3
INSTALLATION
Only skilled personnel should install the machine. All connections must be carried out according to current
regulations, and in full observance of safety laws (regulation CEI 26-23 / IEC-TS 62081)
3�1
Start-up
Make sure that the supply voltage matches the voltage indicated on the specifications plate of the welding machine.
When mounting a plug, make sure it has an adequate capacity, and that the yellow/green conductor of the power
supply cable is connected to the earth pin.
The capacity of the overload cutout switch or fuses installed in series with the power supply must be equivalent to the
absorbed current I1 of the machine.
