1.2 Protect yourself from electric shock by insulating
yourself from work and ground.
1.3 Disconnect input plug or power before working on
machine.
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 fu-
mes.
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 extingui-
sher 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 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 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 61000-3-12 - IEC 61000-3-11 (see
note 2).
N°. Serial number, which must be indicated on any
type of request regarding the welding machine.

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 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.
1~ 50/60Hz 50- or 60-Hz single-phase power supply
I1 max. This is the maximum value of the absorbed cur-
rent.
I1 eff. This is the maximum value of the actual current
absorbed, considering the duty cycle.
IP23S Protection rating for the housing.
12
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 61000-3-11 provi-
ded that the maximum permissible system impedan-
ce Zmax is less than or equal to 0,294 at the inter-
face 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
equipment is connected only to a supply with maxi-
mum permissible system impedance Zmax less than
or equal to 0,294.
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
temperatures are exceeded. The thermostat tripping is
signalled by the glowing abbreviation "OPn" on display
U located on the control panel.
2.3.2 Block protection.
This welding machine is equipped with various protecti-
ve devices that stop the machine to avoid machine dama-
ges. The tripping of each protection device is signalled by
the glowing abbreviation "Err" on display U and by a digit
shown on display O.
If a water low level for the cooling unit is detected
the flashing abbreviation H2O will glow on display U.
3 INSTALLATION
Make sure that the supply voltage matches the voltage
indicated on the specifications plate of the welding ma-
chine.
When mounting a plug, make sure it has an adequate ca-
pacity, 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 in-
stalled in series with the power supply must be equivalent
to the absorbed current I1 of the machine.
3.1. ASSEMBLY
Only skilled personnel should install the machine. All
connections must be carried out according to regulations
in force, and in full observance of safety laws (CEI 26-23
/ IEC-TS 62081)
