2 GENERAL DESCRIPTION

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, START
ENGINES AND CHARGE BATTERIES.
2.2 EXPLANATION
SPECIFICATIONS LISTED ON THE MACHINE
PLATE.
This machine is manufactured according to the following
international standards: IEC 60974.1 - IEC 60974.10 CL.
A - IEC 61000-3-3 - IEC 61000-3-12 (see note 2).
N° serial number, which must always be indi-
cated on any type of request regarding the
welding machine.
Three phase static transformer-rectifi er
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.
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
machine may be stored, but it is not suitable
for use outdoors in the rain, unless it is
protected.
S
Suitable for use in high-risk 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
OF THE TECHNICAL
r.
provided 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.
2.3 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.
2.3.2 Motor-driven generators
These must have a power equal to or greater than 8KVA,
and must not deliver a voltage greater than 270V.
3 INSTALLATION
Make sure that the supply voltage matches the voltage
indicated on the specifi cations 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.
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
26-36 - IEC/EN 69974-9)
3.2 DESCRIPTION OF THE EQUIPMENT
A - Procedure and mode selector switch
This push-button selects the welding procedure
(MMA or TIG) and mode.
The selection changes each time the button is pressed.
The LEDs light alongside the various symbols to display
your choice.
F - LED. MMA welding
This machine can weld all types of covered
electrodes* except for cellulosic.
The welding current is adjusted using the knob H.
