229889 - Miller Head Tube Rotation Nut for Water-Cooled XR-Aluma-Pro

Restore Your Gun's Performance

Keep your Miller water-cooled MIG gun running smoothly with the genuine Miller 229889 Head Tube Rotation Nut. If you are running an XR-Aluma-Pro water-cooled setup, you know how important the rotating head feature is for getting into tight corners and welding in awkward positions. This nut is the key component that holds that head tube in place. Over time, threads can wear or parts can get damaged during routine maintenance and liner changes. Replacing worn hardware is a small step that prevents big headaches down the line.

Don't risk leaks or loose connections with generic substitutes. This OEM part is designed specifically for the water-cooled architecture of your Miller gun, ensuring that coolant stays where it belongs—circulating around the power cable and head—rather than leaking onto your workpiece or floor. A secure head tube also means better current transfer and a more stable arc, which is crucial when welding sensitive materials like aluminum.

Installation is straightforward, allowing you to get back to welding quickly. Whether you are performing a scheduled overhaul of your push-pull gun or replacing a damaged part mid-shift, having a fresh 229889 nut on hand ensures your equipment is ready for the demands of professional fabrication. Trust in Miller's quality to keep your torch assembly tight, leak-free, and fully operational.
