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.
The SAVE/LOAD buttons are used to save and retrieve a total number of 5 programs
into the 200 Pi memory. NOTE: SAVE/LOAD button must remain depressed for 3
seconds in order to save or load the settings.
