A CLOSER LOOK
SPOOL GUN READY!
The POWER MIG
®
255XT has built-in electronics to drive either a
Magnum
®
SG Spool Gun or a Magnum
®
250LX Spool Gun. In
addition, a second gas solenoid is provided to supply and control
gas flow to the spool gun.
Easy as 1-2-3!
Simply plug the spool gun control cable into the built-in 7-pin
connector (Magnum
®
SG gun requires K2445-1, 6- to 7-pin
control cable adapter plug.)
Connect the spool gun’s power cable to the output terminal
in the wire drive compartment.
Hook the spool gun gas line to the solenoid gas fitting and
you’re ready to weld!
