1040086 - Miller MDX-250 Aluminum MIG Gun Neck - 50 Degree Assembly

Optimize Your MDX-250 for Aluminum Welding

The Miller 1040086 Neck Assembly is a critical component for welders utilizing the MDX™-250 MIG gun, specifically tailored for aluminum welding applications. Aluminum wire is notoriously softer and more difficult to feed than steel, often requiring specialized equipment to prevent kinking and birdnesting. This replacement neck features a 50-degree bend angle, which is often preferred for maintaining the correct contact tip-to-work distance while reducing the friction on the wire as it passes through the gun.

Genuine Miller parts ensure seamless compatibility and performance. By swapping your standard neck for this aluminum-specific assembly, you ensure that your MDX-250 operates at peak efficiency. The geometry of the neck is engineered to provide a smooth path for the wire, which is essential for consistent arc stability and high-quality aluminum welds. Whether you are working on automotive repairs, boat fabrication, or general aluminum manufacturing, this neck assembly helps maintain the integrity of your wire feed system.

Installation is straightforward, allowing operators to quickly switch configurations or replace damaged components without significant downtime. Trust in the durability and precision of Miller Electric components to keep your welding operations running smoothly.
