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

Upgrade Your Reach with the Miller 255043 Head Tube

When you are deep in a fabrication project, sometimes a standard curved MIG gun neck just won't cut it. You need a straight shot to get into that tight corner or reach down into a deep assembly. That is exactly what the Miller 255043 Head Tube Assembly delivers. This is a genuine replacement gooseneck for your water-cooled XR-Aluma-Pro or XR-Pistol-Pro push-pull guns, featuring a completely straight, 180-degree design and an 8-inch length that gives you the extension you need to weld where other guns can't.

Built for High-Heat Aluminum Welding
Aluminum welding, especially in spray transfer mode, generates significant heat. Air-cooled necks can overheat quickly, leading to downtime and frustrated operators. The Miller 255043 is fully water-cooled, circulating coolant right up to the nozzle to keep your consumables and the neck itself cool, even when you are pushing high amperage all day long. This means fewer tip changes, less spatter adhesion, and a more comfortable handle temperature for the welder.

Perfect Fit and Easy Swap
Because this is an OEM Miller part, you don't have to worry about O-rings not sealing or the threads stripping out. It is designed to lock perfectly into the front end of your XR series water-cooled guns. Swapping out head tubes is a quick process, allowing you to change from a standard curved neck to this straight 180-degree neck in minutes, minimizing downtime on the production floor. Whether you are working on boat hulls, trailers, or complex aerospace fixtures, having the right neck angle can make the difference between a perfect weld and a struggle.

Key Benefits for the Welder:

• Straight Access: 180-degree angle eliminates the curve, perfect for reaching through holes or into channels.
• Cool Operation: Water-cooling capability handles high duty cycles without overheating.
• Extended Reach: 8-inch length keeps your hand away from the arc and gets the nozzle where it needs to be.
• Reliability: Genuine Miller construction ensures it stands up to daily abuse in the shop.
