warning WARNING: Cancer and Reproductive Harm -
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.

Miller AccuLock MDX series consumables are designed to maximize wire feedability and simplify consumables replacement.

AccuLock MDX Features
Superior Feeding - The front-loading liner is centered and locked at both ends of the gun (without the use of set screws) to ensure smooth wire delivery to the contact tip. Plus, error-proof liner trimming ensures accurate replacement every time for reduced burnbacks, birdnests and erratic arc/wire chatter.

Long-Life Consumables - Tapered mating surfaces between the AccuLock contact tip and gas diffuser lock tips in place for maximized electrical conductivity and longer tip life.

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