255042 - Miller 8-Inch Straight Tube Head for Pro Series Spoolguns

Maximize Your Reach with the Miller 180-Degree Tube Head

For professional welders tackling complex aluminum fabrication, standard curved gun necks don't always cut it. The Miller 255042 Head Tube Assembly is your solution for those hard-to-reach joints. Designed as a straight, 180-degree extension, this 8-inch tube head transforms your Miller Spoolmatic Pro or XR-Pro push-pull gun into a precision instrument capable of diving into deep corners, pipes, and narrow channels where a standard gooseneck would get hung up. It is an essential accessory for any serious fabricator working with the Miller Pro series ecosystem.

Swap Heads in Seconds

Time is money in the shop, and Miller knows it. That's why the 255042 features a revolutionary tool-less connection design. Forget about hunting for a wrench or stripping threads when you need to change your setup. You can pop this head tube onto your gun in seconds. The self-seating design guarantees a perfect connection every time, ensuring you have full gas coverage and consistent arc starts immediately. Whether you are switching from a standard curved neck for bench work to this straight neck for a specific assembly, the transition is seamless.

Ultimate Comfort and Control

Welding out of position can be a nightmare for your wrists. This tube head helps alleviate that strain. Because it is fully rotatable—360 degrees—you can twist the head to match the angle of the joint while keeping your hand and the gun trigger in a natural, comfortable position. This is particularly useful when welding around pipes or fixtures. The ability to rotate the head without loosening a nut means you can make micro-adjustments on the fly, ensuring your travel angle is always spot-on for the perfect bead profile.

Built for Aluminum Pros

This head is specifically engineered for the unique challenges of aluminum wire feeding. Compatible with the XR-Aluma-Pro and Spoolmatic Pro, it maintains the smooth wire path required to prevent bird-nesting and burn-back. The 8-inch length gives you the extra clearance you need without compromising the column strength of the wire. If you are running a Miller Pro series air-cooled gun, adding this straight tube head to your kit opens up a new range of welding possibilities, ensuring you never have to turn down a job because you couldn't reach the weld.
