Miller MDX-250 MIG Gun: Comfort Meets Performance

The Miller MDX-250 MIG Welding Gun (1770041) is engineered to be the welding tool you never have to worry about. Designed with the operator in mind, this 250-amp gun features a 10-foot cable and comes ready to run .035 to .045 inch wire. It represents a significant upgrade in comfort and durability for industrial welding applications. The handle is crafted with a specialized rubber overmolding that improves grip stability while reducing hand strain during long shifts. Additionally, the innovative ball-and-socket rear swivel allows for a freer range of motion, preventing the cable from fighting against you as you maneuver around complex workpieces.

At the heart of the MDX-250's performance is the Bernard AccuLock™ S consumable system. This system is designed to solve common wire feeding issues before they start. The front-loading liner is locked at both the front and back of the gun, ensuring it remains concentrically aligned with the contact tip. This alignment provides a smooth path for the wire, reducing friction and ensuring a stable arc. For welders, this means less troubleshooting and more arc-on time. The liner trimming process is also error-proof; there is no measuring required, which simplifies training and maintenance.

This gun is not just about comfort; it is built for versatility. It is fully compatible with a wide range of Miller power sources, including the Millermatic® 212 Auto-Set™, 252, and 255, as well as the Multimatic® 200 and 255. Whether you are performing general fabrication, maintenance, or repair work, the MDX-250 delivers reliable results. The inclusion of increased copper in the gun cable also makes it pulse-welding capable, ensuring it can handle advanced waveforms without overheating. Upgrade your welding setup with a gun that works as hard as you do.
