TIG spotArc
The TIG SpotArc function is activated with the pulse variant automated frequencies by default, because
this combination produces the most effective results. The user can of course combine the function with
other pulse variants depending on the selected welding process. Pulse time (t1) and pulse break time (t2)
can be set independently, but the spot time (tP) should be much greater than the pulse time in order to
achieve an appropriate result.

The spot time can be set for approx. 4 sec. using the "Welding
parameter setting" rotary dial (spot time setting range
0.01 sec. to 20.0 sec.)
Afterwards the display switches back to current/voltage. If the
button is pressed again, the display switches back to the
parameter and can be changed with the rotary dial
accordingly. The spot time can also be set in the function
sequence.
Set spot time "tP"
The TIG spotArc process is switched on with the pulse variant
"TIG automated pulses" by default. The user can select other
pulse variants:
TIG automated pulses (frequency and balance)
TIG pulses with times, lights up in green/
fast TIG DC pulses with frequency and balance,
