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

This parameter operates in
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
