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 electrically "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® 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. For the Magnum SG Spool Gun, the wire feed speed
is controlled by combination of the wire feed speed
displayed on the POWER MIG® 255XT and the wire
speed control on the spool gun.
See the following procedure for setting the Wire Speed Feed
using the Magnum SG Spool Gun:
To determine spool gun wire feed speed use a hand
tachometer, or calculate the speed using the following equa-
tion:
IPM= Length of wire fed (inches) x 60
Time fed (seconds)
4. To return to normal POWER MIG® 255XT welding,
release the spool gun trigger and reset feeder gun weld-
ing procedures.
