N-M5800C - Miller AccuLock MDX Nozzle 5/8" Flush (2-Pack)

Precision and Reliability with Miller AccuLock MDX Nozzles

Maximize the performance of your Miller MDX-250 MIG gun with the Miller AccuLock MDX Thread-On Nozzle (N-M5800C). Designed as an integral part of the AccuLock MDX consumables system, this nozzle addresses common welding frustrations such as loose front-end parts and erratic wire feeding. This package contains two (2) high-quality copper nozzles, ensuring you have a spare on hand for critical projects.

Stays Tight, Every Time

One of the standout features of the N-M5800C is its thread-on design, reinforced with a specialized steel retaining ring on the diffuser connection. Unlike standard slip-on nozzles that can loosen over time due to thermal expansion and vibration, the AccuLock MDX nozzle remains securely fastened throughout your welding session. This "Stays Tight" technology ensures consistent gas coverage and reduces the frequency of interruptions to retighten components.

Optimized Wire Feeding

The AccuLock MDX system is engineered to provide a flawless wire-feed path. When installed, the nozzle works in conjunction with the contact tip and diffuser to center and lock the liner into position at the front of the gun. This precise alignment eliminates gaps and misalignments that often lead to bird-nesting or erratic arc performance. The result is a smooth, stable arc that allows you to focus on your weld puddle rather than troubleshooting your equipment.

Specifications and Fit

This nozzle features a 5/8-inch orifice, making it a versatile choice for a wide range of amperage settings and wire diameters. The flush tip geometry places the contact tip level with the nozzle opening, offering a balanced combination of gas coverage and stick-out visibility. Constructed from durable copper, it withstands the heat of high-duty cycle welding while maintaining its structural integrity. It is specifically designed for use with Miller MDX-250 and MDX-250 EZ-Select MIG guns.
