ATTENTION: THIS SECTION OF THE PANEL IS CHANGE-
ABLE DURING WELDING.
1. Pre gas.
By pressing function keys 31 e 32 the luminous indicator is posi-
tion at 19 - Picture 1 Page 4.) then by activating the knob 30, the
time length for the gas flux is set up in seconds. The value range
is between 0,2 and 5 seconds.

2. Initial Current
By pressing function keys 31 e 32 32 the luminous indicator is po-
sition at 20 - Picture 1 Page 4.) ; then by activating the knob 30,
the value for the initial current on the mode TIG Four Times is set
up. The value range is between I Min and the nominal current
welding.

3. Ascent Slope.
By pressing function keys 31 e 32 the luminous indicator is posi-
tion at 21 - Picture 1 Page 4.) ; then by activating the knob 30, the
time to reach the nominal current welding in TIG modality is set
up. The value range is between 0 and 10 seconds.
21
4. Nominal Current Welding.
By pressing function keys 31 e 32 the luminous indicator is posi-
tion at 22 - Picture 1 Page 4.) ; then by activating the knob 30, the
value for the nominal current welding for alvl the available modal-
ities is set up. The value range is between 5A and 220A in elec-
trode mode; 5A and 220A.

5. Reduced Current/ Basic Current.
By pressing function keys 31 e 32 the luminous indicator is posi-
tion at 23 - Picture 1 Page 4.) ; then by activating the knob 30, the
WELDING PROCESS PROFILE
value for the reduced current in the Four Times mode is set up. If
the TIG mode is pressed (either Two or Four Times) the pulsation
of the basic current is set up. The value range is between the nom-
inal current welding and the 10% of that same value.
6. Spot Time.
By pressing function keys 31 e 32 the luminous indicator is posi-
tion at 24 - Picture 1 Page 4.) ; then by activating the knob 30, the
time length for the spot impulse is set up in seconds. TIG The val-
ue range is between 0,1 and 10 seconds.
7. Wave-shaped Balance.
By pressing function keys 31 e 32 the luminous indicator is posi-
tion at 25 - Picture 1 Page 4.) ; then by activating the knob 30, the
balance of the different wave shapes pressed on TIG is set up.
The wave-shaped balance can be set up in a value ranging from
1 and 99 for frequencies between 0,3 Hz and 15 Hz. The range
decreases linearly for higher frequencies (up to 250 Hz) up to
range between 30 and 70 (See - Picture 2 Page 7.).
