SPOOL GUN ADAPTER KIT
Remove all input power to the POWER MIG 255
before proceeding.
------------------------------------------------------------------------
The Spool Gun Adapter Kit provides direct connection
and use of the Spool Gun (with remote speed control)
with the POWER MIG 255 wire feed welder.
It also provides gun trigger switch transfer between the
machine’s use with its feeder gun or the spool gun for
same polarity welding with different wire and gas
processes.
The kit includes a spool gun adapter module assembly
with a single connecting plug, a rear gas inlet setting
with hose and mounting hardware with installation and
operation instructions.
*This kit can only be configured to run a Magnum® SG
Spool Gun OR a Prince® XL Spool Gun at a time; kit is
shipped configured for the Magnum® SG Spool Gun.
MAKING A WELD WITH THE SPOOL GUN,
SPOOL GUN INSTALLED
The POWER MIG control circuitry is designed to
sense either the spool gun (built in) wire feeder trigger
circuitry. After the spool gun adapter kit has been
installed, 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 electri-
cally “HOT”.
2. Pulling SPOOL GUN Trigger:
a. Disables built-in feeder gun operation.
b. Closing spool gun trigger starts spool gun
welding and makes both electrodes electri-
cally “HOT”.
3. Operation with POWER MIG 255:
a. Turn the POWER MIG-255 input power
ON.
b. Adjust the voltage control to increase or
decrease your welding voltage.
c. Adjust the wire speed control on the spool
gun to increase or decrease the spool gun
wire feed speed.
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 255 welding
release the spool gun trigger and reset feeder
gun voltage procedure setting if necessary.
6. Operation with Timer Option Kit (K1701-1)
installed in Power MIG 255:
All Timer Option Kit functions, except Run-in,
are functional with the spool gun. (See operat-
ing instructions for Timer Option Kit.
