2 GENERAL DESCRIPTIONS
2.1 SPECIFICATIONS
This welding machine is a DC power source built using
INVERTER technology, engineered to weld with all types
of coated electrodes (cellulosic type not included) and
with TIG welding process with scratch starting and high
frequency.
MUST NOT BE USED TO DEFROST PIPES.
2.2 EXPLANATION OF THE TECHNICAL SPECIFICA-
TIONS 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 / IEC 61000-3-12 (see note 2).
N° . Serial number, which must be indicated on
any request regarding the welding machine.

TIG Suitable for TIG welding.
U0. Secondary open-circuit voltage.
X. Duty cycle percentage.
The duty cycle expresses the percentage of
10 minutes during which the welding machine
can run at a certain current without overheat-
ing.
I2. Welding current
U2. Secondary voltage with current I2

I1 Max Max. absorbed current at the corresponding
current I2 and voltage U2.
I1 eff This is the maximum value of the actual cur-
rent absorbed, considering the duty cycle.
This value usually corresponds to the capacity
of the fuse (delayed type) to be used as a pro-
tection for the equipment.
IP23S Degree of housing protection.
Grade 3 as the second digit means that this
machine may be stored, but it is not suitable
for use outdoors in the rain, unless it is pro-
tected.
S
Suitable for use in high-risk environments.
NOTES:
1- The machine has also been designed for use
in environments with a pollution rating of 3.
(See IEC 60664).
2- This equipment complies with a IEC 2-61000-
3 standard provided that the allowed maxi-
mum impedance Zmax of the unit is lower
or equal to 0.093 (Art. 369) - 0,044 (Art. 370)
- 0,031 (Art. 371) at the interface point be-
tween the user unit and the mains. The tter
or the unit user are responsible for connect-
ing the unit to a power supply with a maxi-
mum allowed system impedance Zmax low-
er or equal to 0.093 (Art. 369) - 0,044 (Art.
370) - 0,031 (Art. 371). If required, they may
contact the electric power supplier to check
this value.
2.3 DESCRIPTION OF PROTECTION DEVICES
2.3.1 Thermal protection
This machine is protected by a number of temperature
probes, which prevent the machine from operating if the
allowable temperatures are exceeded. The thermostat
tripping is signalled by the glowing abbreviation “tH0"
or "tH1" on display D1 located on the control panel.
2.3.2 Alarm display
When the machine detects a temporary alarm, displays
D1 and D2 show a ashing wording related to the alarm
cause (see paragraph 5).
2.3.3 Error display
When the machine detects a serious alarm, displays D1
and D2 show a wording "Err" followed by the relevant
error code.
In this case, switch off the machine and contact technical
service (see par. 5).

Make sure that the supply voltage matches the voltage
indicated on the specications 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 equiva-
