Up Slope
This parameter operates in (4T)
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.

0.0 to 15.0 seconds
Base Current
This parameter sets the TIG
WELD current when PULSE is
OFF. This parameter also sets the
STICK weld current.

Peak Current
This parameter sets the PEAK
weld current when in PULSE
mode.

Trough Current
The lowest point in the pulse is
called the Trough.

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 current. This control is
used to eliminate the crater that
can form at the completion of a
weld.

Crater Current
This parameter operates in (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.
Note: The maximum crater
current available will be limited to
the set value of the base current.
