Miller Spoolmate 3035 Retrofit Switch and Gas Kit

Upgrade Your Welder with the Miller 207642 Field Kit

Unlock the full potential of your Millermatic or Hobart welder with the Miller 207642 Spoolmate Switch & Gas Diverter Kit. If you own a Millermatic 185, Hobart IronMan 210, or IronMan 250 and want to weld aluminum, this kit is the missing link. It is designed to retrofit these older power sources, enabling them to connect and operate the modern Spoolmate 3035 Spool Gun (as well as Spoolmate 185 and 200 Series guns). This eliminates the frustration of incompatibility and saves you the significant expense of purchasing a brand-new welder just to run a spool gun.

The kit solves two primary challenges: electrical control and gas delivery. Older machines often lack the internal solenoid logic to automatically switch between a standard MIG gun and a spool gun. The included process toggle switch mounts directly to your machine, giving you manual control to select the active gun. Simultaneously, the gas diverter valve ensures that your shielding gas—typically 100% Argon for aluminum—is routed correctly to the spool gun, bypassing the standard wire feed path. This ensures a clean, contaminant-free weld every time.

This is a genuine Miller field kit, meaning it meets the high standards of quality and reliability you expect from the brand. It comes complete with the switch, valve, and all necessary mounting hardware. Whether you are a hobbyist looking to tackle aluminum projects or a professional fabricator needing to get more out of your shop's older iron, this kit provides a seamless, professional-grade upgrade path.
