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 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. For the Magnum SG Spool Gun, the wire feed speed is
controlled by combination of the wire feed speed displayed
on the POWER MIG 255C 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 equation:
IPM= Length of wire fed (inches) x 60
Time fed (seconds)
4. To return to normal POWER MIG 255C welding, release the
spool gun trigger and reset feeder gun welding procedures.
