301740 - Miller XR-W Aluma-Pro Plus 35ft Water-Cooled Push-Pull Gun

High-Performance Water-Cooled Aluminum Welding Solution

The Miller XR-W Aluma-Pro Plus Water-Cooled MIG Gun (301740) is an industrial-grade push-pull torch designed specifically for the rigorous demands of heavy-plate and light-gauge aluminum fabrication. Engineered to interface seamlessly with Miller Intellx wire feeders and XR control systems, this 35-foot gun provides exceptional reach and reliability. It is rated for 400 amps of output power, making it ideal for high-duty cycle applications in shipbuilding, truck and trailer manufacturing, and sign fabrication where thermal management is critical.

Precision Wire Delivery System

At the core of the XR-W Aluma-Pro Plus is a sophisticated feeding mechanism capable of delivering wire at speeds up to 900 inches per minute. The gun features aluminum-series-specific tension settings, allowing operators to optimize feeding performance based on whether they are using 4000 or 5000 series aluminum wires. This specificity prevents wire deformation and ensures a stable arc. The drive assembly utilizes an isolated, common, knurled drive roll which minimizes wear and downtime. Furthermore, the replaceable feed cable liner is designed for consistent arc performance and allows for cost-effective maintenance without replacing the entire cable assembly.

Advanced Control and Ergonomics

The gun is equipped with a recessed wire feed speed (WFS) control featuring a 3-3/4 turn potentiometer. This provides superior resolution for fine-tuning parameters at the weld joint, a critical feature for maintaining quality in variable fit-up scenarios. The trigger assembly utilizes a wiping action to maintain clean contact points, ensuring reliable electrical continuity. For maintenance and serviceability, the gun features quick connectors for control cables and a full-length Velcro-seamed leather jacket, offering robust protection against abrasion and spatter while facilitating easy access to the liner and cable leads.
