Parameter
Description
PRE-FLOW
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.
HOT START
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
INITIAL CUR.
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.
UP SLOPE
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.
PEAK CUR.
This parameter sets the PEAK weld current when in PULSE mode.
WELD
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.
BASE (Background Current) This parameter sets the Background current when in Pulse TIG mode.
SPOT TIME
This parameter sets the duration of the SPOT TIME in HF TIG mode only.
PULSE WIDTH
This parameter sets the percentage on time of the PULSE FREQUENCY for PEAK weld
current when the PULSE is on.
PULSE FREQ.
This parameter sets the PULSE FREQUENCY when the PULSE is on.
DOWN SLOPE
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.
CRATER CUR.
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.
