Miller MDX™-250 MIG Welding Gun .035-.045 wire, AccuLock™ MDX Consumables

The best welding gun is the one you never have to think about because it’s comfortable, it’s durable and it gets the job done. MDX Series MIG guns have been designed to be exactly that. The new ergonomic handle features overmolding for improved grip and a rear swivel strain relief for reduced welder fatigue. The gun’s AccuLock™ consumables with dual-locked, front-loading liner ensures smooth, consistent wire feeding for reliable operation.

 

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.
