Miller AccuLock MDX 250 MIG Gun w/Bernard S Lock (177004X)

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 Bernard's S Lock consumables, not Miller MDX AccuLock consumables.

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.
