To regulate the FREQUENCY push the BALANCING and
FREQUENCY key (T4) (FREQUENCY LED flashing) and
use the ENCODER Knob (E) to regulate the value indicated
on the DISPLAY (D).

8) By pushing the WELDING PARAMETERS SELECTION key
a number of times it is possible to set the various TIG WELD-
ING PARAMETERS (see the “TIG AC and DC Welding” par-
agraph - WELDING PARAMETERS).
9) Once the all the selections/regulations indicated above have
been made, welding can begin.
10) During the welding process the DISPLAY shows the real Amps
(A) at which the operator is actually welding.
TIG “DC” welding
1) Start the welding machine by turning the power supply switch
to position I.
2) Press the WELDING PROCESS SELECTION Key (T7) and
select:
L2 a TIG “HF DC” welding process
for direct current TIG welding with
high frequency ignition.
L3 a TIG “Lift DC” welding process
for direct current TIG “Lift” type weld-
ing without high frequency.

WARNING: The “Lift” ignition current is created by pushing
the torch button only after having touched the workpiece with
the electrode.
3) ELECTRODE DIAMETER SELECTION
Select the diameter of the electrode to achieve the best control
of ignition in a synergic manner. Selection is done by pushing
the ELECTRODE DIAMETER Key (T4) (ELECTRODE DIAM-
ETER LED flashing) and using the ENCODER Knob (E) to
regulate the value indicated on the DISPLAY (D).
