N-M58XTC - Miller AccuLock MDX Thread-On Nozzle 5/8" Bore 1/8" Stickout

Experience Flawless Feeding with Miller AccuLock MDX Nozzles

Tired of MIG nozzles that wobble, fall off, or overheat in the middle of a job? The Miller AccuLock™ MDX™ N-M58XTC Thread-On Nozzle is engineered to solve the most frustrating aspects of MIG welding. Designed exclusively for the MDX-250 series MIG guns, this nozzle represents a significant leap forward in consumable technology. The secret lies in the "Stays Tight" guarantee: a coarse-threaded design paired with a durable steel retaining ring ensures your nozzle stays firmly attached to the diffuser, no matter how hot the action gets. Say goodbye to pausing your weld just to push a loose nozzle back on.

Beyond just staying put, the N-M58XTC is a key player in the AccuLock "Optimized Wire-Feeding" system. When you screw this nozzle onto your gun, it helps align the contact tip and the liner perfectly. This alignment eliminates the friction and snagging that often leads to erratic arcs and frustrating wire burnback. The result is a smooth, stable arc that makes you look like a pro, whether you are welding thin sheet metal or heavy structural steel. The 5/8-inch bore is the "goldilocks" size for most applications—large enough to provide excellent gas coverage to prevent porosity, but compact enough to maneuver into corners.

This specific model features a 1/8-inch tip extension (stickout). This means the contact tip pokes out slightly past the end of the nozzle. Many welders prefer this configuration because it offers better visibility of the weld puddle and allows you to get closer to the root of the joint without the nozzle getting in the way. It is ideal for short-circuit MIG welding where seeing the arc is critical.
