Miller MDX™-250 MIG Welding Gun

250A rated output. Next-level advancements include a comfortable new handle with rubber overmolding and rear swivel, optimized wire-feed path for reliable performance, and simplified maintenance.


Durable, Comfortable Handle

Durable handle features rubber overmolding for improved grip and comfort. Ball-and-socket rear swivel provides a freer range of motion to reduce welder fatigue.

Superior Wire-Feeding

Wire delivery is optimized because the front-loading AccuLock liner is locked and concentrically aligned with the contact tip and power pin. Reduces downtime and troubleshooting.

Error-Proof Liner Trimming

No measuring required! Simplifies welder training and prevents downtime and weld quality issues caused by improperly trimmed liners.

Pulse Welding Capable

Increased copper in the gun cable ensures reliable performance with CV and pulse waveforms.

Fewer Parts, More Accuracy

Stock a single line of consumables. AccuLock™ S Consumables can be shared across all of your Miller MDX-250 MIG guns, Bernard® BTB MIG guns and Clean Air™ Fume Extraction MIG guns reducing inventory and decreasing replacement errors.

Long-Life Consumables

Tapered mating surfaces between the AccuLock contact tip and diffuser locks the tip in place for maximized electrical conductivity and lower heat.
