255038 - Miller XR-Aluma-Pro Water-Cooled Head Tube 60 Deg 4 Inch

Genuine Miller Replacement Head Tube

Optimize your welding setup with the Miller 255038 Head Tube Assembly, a premium replacement part designed for water-cooled push-pull MIG guns. This gooseneck assembly is an essential component for welders utilizing the Miller XR-Aluma-Pro system, offering a robust solution for high-heat applications. Featuring a 60-degree bend angle and a 4-inch barrel length, this head tube is engineered to provide superior access to weld joints while reducing operator fatigue. The specific geometry allows for a natural hand position during welding, which is critical for maintaining precision and consistency over long shifts.

The water-cooled design of the Miller 255038 is its standout feature, enabling it to handle the high duty cycles often required in industrial manufacturing, shipbuilding, and heavy fabrication. Unlike air-cooled torches that rely on ambient air and shielding gas to dissipate heat, this water-cooled head tube actively circulates coolant to the nozzle area. This active cooling significantly reduces the operating temperature of the contact tip, preventing the wire from softening prematurely and fusing to the tip—a common issue in high-amperage aluminum welding. Consequently, users experience fewer interruptions for consumable changes and cleaner, more consistent welds.

Durability is at the core of this Miller component. Built to withstand the rigors of the shop floor, the outer jacket is resistant to abrasion and heat, while the internal construction ensures unimpeded coolant flow and electrical conductivity. The head tube is designed for quick and easy replacement, allowing maintenance teams to swap out damaged or clogged necks with minimal downtime. Whether you are welding thick aluminum plate or intricate structural components, the Miller 255038 Head Tube Assembly delivers the reliability and performance necessary to keep your production line moving. Ensure your equipment operates at peak efficiency by choosing genuine Miller replacement parts that guarantee fit, form, and function.
