TITANIUM 400 AC/DC
EN
Rising current
0 - 60 sec.
Current rise ramp.
Welding current
3 - 400 A
Welding current.
Cold weather
80% - 100 %
Second welding current known as «cold» welding current
Pulse frequency
2.5 - 20 kHz
Pulse frequency
Downslope
0 - 60 sec.
Downslope current.
End current
10 - 200 %
This stopping stop current is a phase after the current descent ramp.
End duration
0 - 10 sec.
Post-gas
0 - 60 sec.
Duration for which gas is released after the arc has stopped. It protects the weld pool
and the electrode against oxidisation when the metal is cooling down.
TIG AC WELDING
TIG AC - Standard
This TIG AC - Standard welding mode is dedicated to welding aluminium and its alloys (Al, AlSi, AlMg, AlMg, AlMn...). Alternating current allows the
pickling of aluminium essential for welding.

Description & advice
Pre-gas
0 - 60 sec.
Time to purge the torch and to protect the area with gas before ignition
Starting current
10 - 200 %
This starting bearing current is a phase before the current rise ramp.
Starting time
0 - 10 sec.
Rising current
0 - 60 sec.
Current rise ramp.
Welding current
3 - 400 A
Welding current.
Downslope

Downslope current.
End current
10 - 200%
This stopping stop current is a phase after the current descent ramp.
End duration
0 - 10 sec.
Post-gas
0 - 60 sec.
Duration for which gas is released after the arc has stopped. It protects the weld pool
and the electrode against oxidisation when the metal is cooling down.
AC wave shape
AC waveform.
Welding frequency
20 - 300 Hz
Frequency of polarity reversals welding - pickling
Percentage of
pickling
20 - 60 %
Percentage of the welding period dedicated to pickling (default 30-35%)
The Balance (%T_AC):
during the positive wave, the oxidation is broken. During the negative wave, the electrode cools and the parts are welded, there is penetration. By
modifying the ratio between 2 alternatives through the balance adjustment, you choose either cleaning or penetration (the default value is 30%).
20%: Max. penetration
50%
60%: Max. pickling
