Frequency of
welding
20 - 300 Hz
Frequency of polarity reversals welding - pickling
Penetration and clea-
ning (%)
20 - 60%
Percentage of the welding period dedicated to pickling (default 30-35%)
MUTLI SPOT (TIG DC or AC)
This is a scoring mode similar to the TIG SPOT, but with a combination of scoring and stopping time defined as long as the trigger is held in.

Description & advice
Pre-gas
0 - 60 sec.
Time to purge the torch and to protect the area with gas before ignition
Welding current
3 - 400 A
Welding current.
Spot
, 0 - 60 sec.
Manual or a defined time.
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.
Duration between 2
points
0.1 - 20 sec.
Time between the end of a point (excluding PostGaz) and the recovery of a new point
(including PreGas).

TACK (TIG DC)
This mode can also pre-assemble workpieces, but in two phases : first phase is DC pulse whcih concentrates the arc for enhanced penetration, fol
-
lowed by a DC standard phase which enlarges the arc and the weld pool for a good spot.
The adjustable duration of each phase enables control of the weld time for better spot welding results and an non-oxidised spot.
