250 A Gas Diffuser for MDX-100

The Miller Enterprises 1770028 D-M100 gas diffuser fits Miller MDX-100 MIG guns. It handles up to 250 amps and uses a threaded connection for quick replacement. The part supports both MIG and flux-cored welding processes. A cooling tail helps manage heat during operation.

Suits MDX-100 gun owners; not for other guns

This diffuser is built for welders running Miller MDX-100 series guns with AccuLock MDX contact tips and nozzles. It will not fit guns from other series or brands that use different mounting styles. Buyers needing a diffuser for a non-MDX gun should look elsewhere.

Threaded connection with cooling tail

The threaded connection type secures the diffuser to the MDX-100 gun and allows fast changeovers. The integrated cooling tail directs heat away from the consumable stack. This combination of connection style and cooling feature determines fit and thermal performance.
