Parameter Description
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.
POST-FLOW
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.
