Fi gur e4-3:
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 BASE (WELD) current.
e.g. HOT START current = 130 amps when BASE (WELD) = 100 amps & HOT START = 30 amps
This parameter operates in SLOPE or REPEAT (4T) TIG modes only and 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.
This parameter sets the PEAK weld current when in PULSE mode.
This parameter sets the TIG WELD current in STD, SLOPE, REPEAT and SPOT modes when
PULSE is off. This parameter also sets the STICK weld current.
This parameter sets the Background current when in Pulse TIG mode.
This parameter sets the duration of the SPOT TIME in HF TIG mode only.
This parameter sets the percentage on time of the PULSE FREQUENCY for PEAK weld current
when the PULSE is on.
This parameter sets the PULSE FREQUENCY when the PULSE is on.
This parameter operates in TIG modes only and is used to set the time for the weld current to ramp
down, after the torch trigger switch has been pressed, to CRATER CUR. This control is used to
eliminate the crater that can form at the completion of a weld.
This parameter operates in SLOPE or REPEAT (4T) TIG modes only and is used to set the finish
current for TIG. The CRATER Current remains on until the torch trigger switch is released after it
has been depressed.
