This is a Lincoln Spool Gun Adapter Kit. It is designed to allow you to use your Magnum SB or Magnum 250LX spool gun with the Power MIG. The gun connection panel has a 6-pin MS-type connector for the Magnum SG spool gun, and a 7-pin MS-type connector for the Magnum 250LX spool gun. There is a handy selector switch to choose which gun you are using.
Note: This spool gun adapter disables the Magnum 100SG capability.
