MAKING A WELD WITH THE
PRINCE XL SPOOL GUN
The POWER MIG 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.
Closing either gun trigger will cause the
electrode of both guns to be electrically "HOT".
Be sure unused gun is positioned so electrode
or tip will not contact metal case or other metal
common to work.
----------------------------------------------------------------
1. Pulling the trigger for the built-in feeder gun:
a. Disables spool gun operation.
b. Closing feeder gun trigger starts feeder gun
welding and makes both electrodes electrical-
ly "HOT".
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 255C:
a. Turn the POWER MIG 255C 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 255C wire
feed speed(WFS) meter will display the approx-
imate WFS of the gun. Actual WFS at the gun
may vary from the displayed value due to ten-
sion setting, 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 255C welding,
release the spool gun trigger and reset feeder gun
voltage procedure setting if necessary.
