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.
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
HOT START 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
INITIAL CUR. 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
UP SLOPE 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.
AC FREQUENCY
This parameter operates in AC mode only and is used to set the frequency for the AC weld
current.
