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
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.

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 61000-3-12 - 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-rectifier
frequency 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 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 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.

2.3 DESCRIPTION OF PROTECTIVE DEVICES
2.3.1 Thermal protection
This equipment is protected by a thermostat. When the ther-
mostat 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.
2.3.2 Motor-driven generators
These must have a power equal to or greater than 6KVA, and
must not deliver a voltage greater than 270V.
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 capa-
city, and that the yellow/green conductor of the power sup-
ply 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.
3.1 START-UP
Only skilled personnel should install the machine. All con-
nections must be carried out according to current regula-
tions, and in full observance of safety laws (regulation CEI
26-23 - IEC/TS 62081).
3.2 DESCRIPTION OF THE EQUIPMENT
The selection changes each time the button is pressed.
The LEDs light alongside the various symbols to display your
choice.
This machine can weld all types of covered electrodes*
except for cellulosic.
The welding current is adjusted using the knob H.
without high frequency.

that the maximum permissible system impedance Zmax
is less than or equal to 0,388 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 equipment is connected
only to a supply with maximum permissible system
impedance Zmax less than or equal to 0,388
