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.

TACK DELAY (TIG DC)
This is the same mode as the TIG DC TACK, but with a sequence of scores and defined stopping times as long as the trigger is held in.
