2 Breathing welding fumes can be hazardous to your
health.
2.1 Keep your head out of fumes.
2.2 Use forced ventilation or local exhaust to remove
fumes.
2.3 Use ventilating fan to remove fumes.
3 Welding sparks can cause explosion or fire.
3.1 Keep flammable materials away from welding.
3.2 Welding sparks can cause fires. Have a fire extin-
guisher nearby and have a watchperson ready to use
it.
3.3 Do not weld on drums or any closed containers.
4 Arc rays can burn eyes and injure skin.
4.1 Wear hat and safety glasses. Use ear protection and
button shirt collar. Use welding helmet with correct
shade of filter. Wear complete body protection.
5 Become trained and read the instructions before
working on the machine or welding.
6 Do not remove or paint over (cover) label.

2 GENERAL DESCRIPTIONS

2.1 SPECIFICATIONS
This welding machine is a constant current power source
built using INVERTER technology, designed to weld covered
electrodes (not including cellulosic) and for TIG procedures,
with contact starting and high frequency.
IT MUST NOT BE USED TO DEFROST PIPES.
2.2 EXPLANATION OF THE TECHNICAL SPECIFI-
CATIONS 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 61000-3-11 - 61000-3-12 (see
note 2).
N°. Serial number, which must be indicated on any
type of request regarding the welding machine.
Three phase static transformer-rectifier frequency
converter.
Drooping-characteristic.
MMA 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 machine may run at a certain
current without overheating.
I2. Welding current
U2. Secondary voltage with current I2
U1. Rated supply voltage
The machine has an automatic supply voltage
selector.
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 envi-
ronments 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 0,117(Art. 362) - 0,137 (Art. 360)
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
distribution network operator if necessary, that the equip-
ment is connected only to a supply with maximum per-
missible system impedance ZMAX less than or equal to
0,117(Art. 362) - 0,137 (Art. 360).
2.3 DESCRIPTION OF PROTECTIVE DEVICES
2.3.1. Thermal protection
This machine is protected by a temperature probe, which
prevents the machine from operating if the allowable tem-
peratures are exceeded. Under these conditions the fan
keeps running and the LED M lights.
2.3.2 - Block protection art. 338
This welding machine is equipped with various safety
devices that stop the machine before it can suffer damage.
The welding machine may operate within the following volt-
age ranges:
For rated voltage 208/220/230V, from 175 to 270V
For rated voltage 400/440V, from 340 to 490V
Caution: if the supply voltage does not fall between the
above values, no LED will light and the fan is powered.
If the phases are not properly connected, 3 light points will
appear (steadily lit) on the display P when the machine is
started.
If, with the machine on, the voltage falls below 175 V (U1 =
230V) or 340 V (U1 = 400V), the display P will show the
abbreviation E3.
If, with the machine on, the voltage rises above 275 V (U1 =
230V) or 490 V (U1 = 400V), the display P shows the abbre-
viation E4.
In this case turn off the machine, restore the proper voltage
and restart. If the problem has been corrected, the welding
machine will begin operating again.
If, with the machine on, the display P shows the message E2
or E1, check the supply voltage of the machine; if it is cor-
rect, the machine requires technical service.
If a low water level is detected for the cooling unit the
abbreviation H2O flashes on the display P.
3 INSTALLATION
Make sure that the supply voltage matches the voltage indi-
cated 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.
WARNING! Extension cords of up to 30m must have a
cross-section of at least 2.5 mm2.
