301569 - Miller XR-Aluma-Pro Push-Pull Gun 300A 25ft Air-Cooled

Precision Aluminum Feeding Performance

Unlock the full potential of your aluminum welding setup with the Miller XR-Aluma-Pro A Gun, 25 ft (301569). This air-cooled push-pull gun is rated for 300 Amps at 100% duty cycle, providing the power needed for heavy-plate applications while maintaining the finesse required for light-gauge work. It is engineered to feed aluminum wire at speeds up to 900 inches per minute, significantly faster than predecessors, ensuring high deposition rates and improved productivity. The gun is compatible with Miller's XR-Control, XR-AlumaFeed, and select Millermatic power sources, offering a seamless integration into your existing welding system.

Advanced Tension Control

One of the standout features of the XR-Aluma-Pro is its series-specific tension settings. The gun allows operators to select between tension profiles optimized for 4000 or 5000 series aluminum wires. This precision ensures that the drive rolls provide the exact amount of grip needed without deforming the soft wire, preventing shaving and feeding issues that can compromise weld quality. Additionally, the 3-3/4 turn potentiometer provides high-resolution wire feed speed adjustment right at the gun, allowing welders to fine-tune parameters on the fly while wearing gloves, thanks to the recessed, durable control dial.

Versatility and Access

The XR-Aluma-Pro is designed to adapt to various welding scenarios. The standard 25-foot cable provides excellent reach, ideal for working on large structures like truck bodies or railcars. The head tube is not only rotatable but also self-seating, preventing gas leaks and ensuring optimal current transfer. For specialized applications, over 30 different styles of head tubes are available (sold separately), including various bends and lengths. Whether you are welding intricate sign components or heavy-duty heat exchangers, the Miller XR-Aluma-Pro A Gun delivers the reliability and control necessary for superior aluminum welds.
