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
position 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.
19
2. Initial Current
By pressing function keys 31 e 32 the luminous indicator is
position 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.
20
3. Ascent Slope.
By pressing function keys 31 e 32 the luminous indicator is
position 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
position at 22 - Picture 1 Page 4.) ; then by activating the knob
30, the value for the nominal current welding for all the available
modalities is set up. The value range is between 5A and 220A in
electrode mode; 5A and 220A.
5. Reduced Current/ Basic Current.
By pressing function keys 31 e 32 the luminous indicator is
position at 23 - Picture 1 Page 4.) ; then by activating the knob
30, the value for the reduced current in the Four Times mode is
set up.
22
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 nominal current welding and the 10% of that same
value.
Spot Time.
6.
By pressing function keys 31 e 32 the luminous indicator is
position 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 value range is between 0,1 and 10 seconds.
7. Wave-shaped Balance.
By pressing function keys 31 e 32 the luminous indicator is
position 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.).
