DARD POWER MIG FEEDER
FAST OR SLOW RUN-IN MODE SELECTION,
(When Timer Option is not installed)
The POWER MIG® 255XT is factory set for fast run-in mode
where the wire feed will accelerate directly to the preset wire
feed speed when the gun trigger is closed.
Slow run-in mode may also be selected, where it will initially
feed wire at 50 IPM until output current is sensed or for 1.0
seconds, whichever occurs first. After which it will accelerate
to the preset wire feed speed.
Note: See operating instructions for Timer Option Kit
if it is installed, as it provides its own Run-in operation.

1. Turn power OFF on front panel of POWER MIG® 255XT.
2. Turn the wire feed speed dial to minimum, fully counter-
clockwise.

On the initial trigger closure at power up, no output power or
wire feed will be available until the trigger is opened and
reclosed, regardless of wire feed speed dial setting.
