Copper thread-on nozzle for MDX-250 MIG guns

This Miller Enterprises AccuLock MDX nozzle fits directly onto compatible MIG guns using a thread-on design. It is made from copper for thermal conductivity during welding tasks. The nozzle works with the AccuLock MDX contact tip system and D-M250 diffuser. It suits welders maintaining or repairing MDX-250 equipment.

1/2 inch orifice with 1/8 inch tip recess

The nozzle has a 1/2 inch orifice and a 1/8 inch tip recess that set the contact tip position relative to the gas shroud. This geometry affects gas coverage and tip life on the MDX-250 platform. It is not suited for guns that use slip-on nozzles or different recess dimensions. Builders needing a different orifice size or recess should select another part.

Questions about this item

What does the 1/2" orifice diameter mean when the nozzle is fitted to an MDX-250 gun?

The 1/2" orifice sets the gas coverage area around the wire, matching the MDX-250's flow requirements for consistent shielding.

How does the AccuLock MDX thread interface affect tip changes on this copper nozzle?

The AccuLock MDX threads lock the contact tip securely, allowing quick tip swaps without removing the nozzle from the diffuser.
