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.
This parameter operates in TIG modes only and is used to adjust the post
gas flow time once the arc has extinguished. This control is used to
dramatically reduce oxidation of the tungsten electrode.
