The Miller 258475 is a premium replacement Head Tube Assembly designed specifically for high-performance water-cooled push-pull MIG guns. Engineered to fit the Miller XR-Aluma-Pro and XR-Pistol-Pro series, this component is critical for maintaining the thermal management and structural integrity of your welding system during heavy-duty fabrication. The assembly features a 180-degree straight configuration, which is often required for specific fixture setups, automated welding carriages, or manual welding applications where a straight approach provides better visibility and access than standard curved necks.
With a 4-inch length, this head tube offers a compact profile that does not compromise on reach. It is built to accommodate the Centerfire consumable system, a favorite among industrial welders for its threadless contact tips and superior gas diffusion. The water-cooled architecture of this head tube ensures that it can withstand high amperage outputs for extended periods without overheating, protecting both the consumables and the gun liner. Proper cooling is essential when welding aluminum, as it prevents wire burn-back and ensures consistent wire feeding.
Replacing a damaged or clogged head tube is vital for preventing coolant leaks and ensuring proper electrical conductivity. The Miller 258475 is manufactured to precise OEM specifications, ensuring a perfect seal and seamless electrical connection with the gun body. Whether you are welding thick aluminum plate in the marine industry or fabricating specialized transport trailers, this head tube assembly delivers the reliability required for professional results.
