The Miller MDX 250 MIG gun has been redesigned with a few new features. The new ergonomic handle features and overmolding for improved grip and a rear swivel strain relief. The gun’s AccuLock consumables with dual-locked, front-loading liner ensures smooth, consistent wire feeding for reliable operation. This particular MIG gun utilizes Miller's MDX Acculock consumables, not Bernard S Lock consumables. Bernard S Lock consumables may be used, however you would need to swap out the diffuser, contact tip, and nozzle.

Threaded Nozzle - Stays tight during use and cleaning due to the steel retaining ring on the diffuser.
