2 gENERAL DESCRIPTIONS

2.1 SPECIfICATIONS
this welding machine is a constant current power source
built using inverter technology, designed to weld cov-
ered electrodes (not including cellulosic) and for tig pro-
cedures, 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 60974.10 cl. a
- iec 61000-3-11 - iec 61000-3-12 (see note 2).

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

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 0,137 (art. 514) and 0,081 (art.
519) 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
0,137 (art. 514) and 0,081 (art. 519).
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 cur-
rent 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.
3 INSTALLATION
make sure that the supply voltage matches the voltage
indicated 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 equiva-
lent to the absorbed current i1 of the machine.
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
a) Setting knob
during MMA welding it adjusts the "hot-start" current
time , expressed in hundredths of a second; essentially, it
sets an overcurrent that serves to improve striking. it
does not make any adjustment during continuous TIg
welding.
in pulsed TIg welding, it adjusts the pulse frequency in
hz.
during welding processes in which the knob is active, the
value of the adjustment is shown on the display I. two
seconds after the last adjustment the display returns to
showing the figure previously selected using the selector
switch O.
B) Thermostat LED
(see 2.3.1. thermal protection).
