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.

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.
