301573 - Miller XR-Aluma-Pro 35ft Water-Cooled Push-Pull Aluminum MIG Gun

High-Performance Aluminum Welding Solution

The Miller XR-Aluma-Pro Water-Cooled Push-Pull Gun (301573) is a premier solution designed specifically for the rigors of industrial aluminum welding. Engineered to address the common challenges associated with feeding soft aluminum wires, this 35-foot gun utilizes advanced push-pull technology to ensure smooth, consistent wire delivery over long distances. With a robust 400-amp output at 100% duty cycle, it is built to handle the most demanding fabrication schedules without overheating or compromising arc stability.

Precision Control and Ergonomics

One of the standout features of the XR-Aluma-Pro is its focus on operator control and comfort. The gun features a 3-3/4 turn potentiometer that provides exceptional resolution, allowing welders to dial in the exact wire feed speed required for the job. The WFS control is recessed into the handle, protecting it from accidental adjustments or damage while remaining easily accessible even with welding gloves. Weighing in at just 2.9 lbs (1.3 kg), the gun is significantly lighter than many competitors, reducing wrist and arm fatigue during extended welding sessions. The balanced design further enhances maneuverability, making it easier to access tight joints and maintain proper gun angles.

Optimized for Aluminum Alloys

Miller has equipped this gun with aluminum-series-specific tension settings, ensuring optimal feeding performance whether you are working with 4000 or 5000 series aluminum wires. The gun supports wire diameters ranging from .030 to 1/16 inch. Maintenance is streamlined with a replaceable feed cable liner and a self-seating head tube that can be rotated to prevent leaks and improve current transfer. The trigger assembly features a wiping action to keep contact points clean, ensuring reliable electrical connections shift after shift. For shops dedicated to high-quality aluminum fabrication, the XR-Aluma-Pro is an indispensable tool.
