PARAMETER
DESCRIPTION
This parameter operates in TIG modes only and is used to get 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.
PRE-FLOW
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
HOT START
characteristics for stick electrodes. e.g. low hydrogen electrodes. It sets
the peak start current on top of the PEAK (WELD) current.
e.g. HOT START current = 130 amps when PEAK (WELD) = 100 amps &
HOT START = 30 amps
This parameter operates in SLOPE or REPEAT (4T) TIG modes only and
INITIAL CUR.
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
