In this mode the torch trigger switch is
pressed to start the arc. After the PRE
FLOW gas time has elapsed, the Arc will
start and the current will stay at the START
CURRENT setting.
When trigger is released the current will
increase to the WELDING CURRENT
setting according to the UP SLOPE time.
Output will continue at WELDING
CURRENT setting.
When the torch trigger is pressed again,
then the weld output will decrease down to
FINAL CURRENT setting according to the
DOWN SLOPE time.
Weld output will remain at FINAL CURRENT
until torch trigger is released, then gas will
flow for POST FLOW time.
NOTE: 4T trigger cannot be selected or
used with Foot Controller.
