Base current
Unit % (of main current I
1
)
Setting range 0 - 100
Polarity
Unit -
Setting range AC (only MagicWave) / DC- / DC+
AC frequency
only with MagicWave for the TIG AC welding process
Unit Hz
Setting range Syn / 40 - 250
Syn for mains synchronisation of two power sources for simultan-
eous AC welding.
IMPORTANT! If using the "Syn" setting, remember to check the "Phase sync." para-
meter in AC setup 2nd.
Low frequency soft, wide arc with shallow heat input
High frequency focused arc with deep heat input
AC-current offset
only with MagicWave for the TIG AC welding process
Unit %
Setting range -70 to +70
+70 highest fusing power, lowest cleaning action
-70 narrow arc, deep heat input, faster welding speed
Balance
only on MagicWave for TIG AC welding process
Unit -
Setting range -5 - +5
-5: wide arc with shallow heat input
+5: highest cleaning action, lowest fusing power
Spot welding time
Unit s
Setting range OFF / 0.05 - 25.0
If a value has been set for the spot welding time, "2‑step mode" will work in the same
way as spot welding mode.
Starting current time
Unit s
Setting range OFF / 0.01 - 9.9
The starting current time t-S specifies the duration of the starting-current phase I
s
.
IMPORTANT! The starting current time only applies in 2-step mode. In 4-step mode,
the duration of the starting-current phase I
s
is controlled using the torch trigger
