Precision Copper Nozzle for MDX-250 Guns

This 15.9 mm copper welding nozzle fits Miller MDX-250 MIG guns. It is built for welders who need a direct replacement consumable that matches the original equipment specification. The copper construction delivers reliable electrical conductivity and heat resistance during standard MIG welding tasks.

Build Integration with AccuLock System

The nozzle threads onto a D-M250 diffuser and works with AccuLock MDX contact tips and compatible liners. It frees the operator from fitting mismatched parts that can cause gas leaks or tip wear. Buyers who need a different bore size or a nozzle for another gun series should select the correct model for their specific torch.

Questions about this item

How long does the 15.9 mm copper bore last on a 250 amp MIG gun before it wears out?

The copper nozzle is built for the MDX-250 gun; bore life depends on wire feed speed, duty cycle and spatter levels in your specific application.

Does the nozzle get too hot to touch during an all-day 250 amp welding shift?

Copper conducts heat quickly; the nozzle will become very hot during continuous high-amperage use, so always wear appropriate gloves when handling.
