301571 - Miller XR-Aluma-Pro Water-Cooled Push-Pull Gun 15ft 400A

Miller XR-Aluma-Pro Water-Cooled MIG Gun (15 ft) - 301571

The Miller XR-Aluma-Pro Water-Cooled MIG Gun (SKU: 301571) represents the pinnacle of push-pull wire feeding technology for industrial aluminum applications. Designed specifically to address the challenges of feeding soft aluminum wires, this 15-foot water-cooled system ensures consistent arc performance and wire delivery, even at high speeds. With a rated output of 400 Amps, it is built to handle heavy-duty fabrication environments found in shipbuilding, truck and trailer manufacturing, and sign fabrication.

Optimized for Aluminum Fabrication

Feeding aluminum wire can be difficult due to its softness and tendency to buckle. The XR-Aluma-Pro solves this with a dedicated push-pull mechanism that synchronizes with the wire feeder. A standout feature is the dual wire tension setting, which allows operators to toggle between tension profiles optimized for 4000 series (softer) or 5000 series (stiffer) aluminum alloys. This precision ensures the very best feeding performance and arc consistency, minimizing downtime caused by wire feeding issues.

Ergonomics and Durability

Welder fatigue is a critical factor in production efficiency. The XR-Aluma-Pro is engineered to be lighter than previous models while maintaining a rugged exterior capable of withstanding harsh industrial conditions. The gun features a balanced design and a natural feel, improving joint access and allowing welders to maintain proper gun angles. The trigger hold feature further reduces fatigue by allowing operators to weld without continuously depressing the trigger (when paired with compatible controls). Additionally, the 360-degree rotatable head tube allows for easy adjustment to fit various weld angles without tools.

Serviceability and Maintenance

Maintenance is streamlined with the XR-Aluma-Pro. The gun features a replaceable feed cable liner, allowing you to replace just the liner rather than the entire feed cable, significantly reducing parts costs. Easy access to the drive assembly and a removable head tube mean that routine maintenance or drive roll changes can be performed quickly, keeping your production line moving. The full-length Velcro-seamed leather jacket provides excellent protection for the cable bundle while allowing easy access for service.
