227158 - Miller XR-Aluma-Pro Air-Cooled Head Tube, 60 Degree, 4-Inch

Restore Your Aluma-Pro's Performance

If you are welding aluminum with a Miller XR-Aluma-Pro or Pistol-Pro, you know that the condition of your gun's front end makes or breaks your day. The Miller 227158 Head Tube is the standard "short" gooseneck for air-cooled models, featuring a comfortable 60-degree bend. Over time, head tubes can get banged up, threads can strip, or the internal passage can become clogged with spatter and aluminum shavings. When that happens, your gas coverage suffers, and your wire starts to drag. Swapping out your old tube for a fresh 227158 is one of the quickest ways to get your machine running like new again.

Why Choose the Brazed Model?
This isn't just a bent pipe; it's a brazed assembly. Miller uses brazing to create a solid, durable unit that handles heat better and conducts electricity more efficiently than cheaper alternatives. This means a smoother arc and less heat buildup in your hand during long welds. The 4-inch length is perfect for general fabrication—it's short enough to give you great control over the puddle but long enough to keep your hand away from the immediate heat zone.

Easy Installation and Versatility
One of the best features of the Aluma-Pro system is the rotatable head tube. This replacement part fits perfectly into the gun body, allowing you to loosen the retention nut and rotate the neck 360 degrees. This is a lifesaver when you are trying to weld underneath a boat hull, inside a truck box, or around a roll cage. Don't fight a damaged torch; replace the neck and get back to laying down perfect dimes.
