Millermatic 135 / 175 Spoolgun Switch 300409

The Millermatic 135 / 175 spoolgun switch 300409 is still available at  BRWELDINGSUPPLIES.COM . This switch allows a Norstar  spoolgun  Badger  or Miller Spoolmate 100 to be hooked up to the Millermatic 135 & 175  models after serial # LC175022 . Before that serial number you would have to cut the white plugs off and use butt connectors and hard wire the switch in.

Serial# is LC175022 and above ( with the 2 pin square drive motor plugs)
the switch plugs into the harness . If it is a lower serial number , you have to do some wiring , but not hard to do)
