Miller AccuLock MDX 250 MIG Gun Diffuser (Pkg/2) (D-M250)

Miller AccuLock MDX series consumables are designed to maximize wire feedability and simplify consumables replacement. Diffusers are sold as a package of two. 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.
