2. Pulling SPOOL GUN Trigger:
a. Disables built-in feeder gun operation.
b. Closing spool gun trigger starts spool gun weld-
ing and makes both electrodes electrically "HOT".
3. Operation with POWER MIG® 255XT:
a. Turn the POWER MIG® 255XT input power ON.
b. Adjusting the voltage control will increase or
decrease your welding voltage.
c. Adjusting the wire speed control on the spool gun
will increase or decrease the spool gun wire feed
speed.
d. To aid in set-up, the POWER MIG® 255XT wire
feed speed(WFS) meter will display the approxi-
mate WFS of the gun. Actual WFS at the gun may
vary from the displayed value due to tension set-
ting, liner condition or gun variation.
4. The following procedure settings for Aluminum
4043 can be used as initial settings for making test
welds to determine final settings:
5. To return to normal POWER MIG® 255XT welding,
release the spool gun trigger and reset feeder gun
voltage procedure setting if necessary.

MAGNUM SG SPOOL GUN
The POWER MIG® 255XT control circuitry is
designed to sense either the spool gun or (built in) wire
feeder trigger circuitry. The spool gun can easily be
plugged in and will be ready to use.
