255043 - Miller Water-Cooled 180-Degree Head Tube for XR-Aluma-Pro/Pistol-Pro

Miller 255043 Head Tube Assembly Overview

The Miller 255043 Head Tube Assembly is a specialized component designed for high-performance industrial welding applications. Engineered specifically for use with Miller's advanced push-pull aluminum welding systems, including the XR-Aluma-Pro™ and XR-Pistol-Pro™ water-cooled guns, this head tube ensures optimal performance and reliability. As a genuine Miller OEM part, it guarantees precise fitment, ensuring that coolant channels seal correctly to prevent leaks and maintain efficient thermal transfer during operation.

This particular assembly features a 180-degree straight geometry. Unlike standard curved goosenecks (such as 45 or 60 degrees), the straight design of the 255043 allows welders to access deep, narrow channels, pipe interiors, or obstructed joints where a curved neck would be physically impeded. The 8-inch length further enhances this reach, providing the necessary clearance to weld in difficult positions without compromising the welder's comfort or the gun's wire feeding capabilities.

Water cooling is a critical feature of this head tube, making it suitable for high-amperage applications often found in shipbuilding, heavy manufacturing, and aluminum fabrication. The efficient cooling circuit within the tube protects the consumables and the gun itself from the intense heat generated during spray transfer welding, significantly extending the duty cycle and the lifespan of the front-end parts. By maintaining lower operating temperatures, the risk of wire burn-back and contact tip failure is reduced, leading to more consistent arc stability and weld quality.

Installation is straightforward, designed to integrate seamlessly with the modular nature of the XR-Aluma-Pro and Pistol-Pro series. The robust construction ensures durability against mechanical impact and thermal stress, making it a dependable choice for rigorous industrial environments. Whether replacing a damaged component or reconfiguring a welding gun for a specific joint geometry, the Miller 255043 delivers the quality and performance professionals expect from Miller Electric.
