This parameter operates in TIG modes only and is used to provide gas
to the weld zone prior to striking the arc, once the torch trigger switch
has been pressed. This control is used to dramatically reduce weld
porosity at the start of a weld.
This parameter operates in all weld modes except Lift TIG mode and
is used to heat up the weld zone in TIG modes or improve the start
characteristics for stick electrodes. e.g. low hydrogen electrodes.
It sets the peak start current on top of the
HOT START
e.g. current = 130 amps when
& HOT START = 30 amps.
This parameter operates in
is used to set the start current for TIG. The Start Current remains on until
the torch trigger switch is released after it has been depressed.
This parameter operates in TIG modes only and is used to set the time
for the weld current to ramp up, after the torch trigger switch has been
pressed then released, from INITIAL CUR to PEAK or BASE current.
