OVERVIEW

Miller 137551 XR-15A Aluminum MIG Gun

Unlock the full potential of your aluminum welding operations with the Miller XR-15A Gun and Cable Assembly (137551). This premium push-pull gun is the industry standard for feeding aluminum wire reliably. Standard MIG guns rely solely on pushing wire from the feeder, which works well for steel but often fails with soft aluminum, causing the wire to buckle inside the liner. The XR-15A solves this by incorporating a small, powerful motor in the gun itself that works in tandem with the feeder motor, maintaining constant tension on the wire for a smooth, stable arc.

The "15A" designation indicates a 15-foot cable length and air-cooled operation. This configuration is perfect for shops that need a balance between reach and simplicity. Without the need for a water cooler, the setup remains portable and less complex, while still capable of handling significant amperage for typical aluminum gauges. The assembly features a rugged outer jacket that protects the power cable, gas hose, and control leads from abrasion and cuts, ensuring a long service life in tough environments.

Compatibility is key with the XR series. This gun is designed to interface directly with Miller XR control boxes and feeders, providing a plug-and-play solution for upgrading or replacing existing equipment. The contact tips, nozzles, and liners are standard Miller consumables, ensuring that parts are readily available and easy to source. Whether you are welding truck boxes, trailers, or architectural aluminum, the Miller XR-15A provides the consistent performance required for X-ray quality welds.

FAQ

The XR-15A comes with a 15-foot (4.6 meter) cable assembly.

The Miller XR-15A is an air-cooled push-pull gun.

It is specifically designed for feeding soft aluminum welding wire, such as 4043 and 5356 alloys.

Yes, it requires a compatible Miller XR series wire feeder or control box to operate the push-pull mechanism.

While physically possible, push-pull guns are expensive and specialized for soft wires like aluminum. Using them for steel is generally not recommended due to unnecessary wear.

It uses standard Miller FasTip or similar contact tips and nozzles depending on the specific front-end configuration.

The push-pull design itself prevents birdnesting by pulling the wire at the gun while the feeder pushes, eliminating the compressive force that causes buckling.
