300948 - Miller XR-Aluma-Pro Lite 175A Push-Pull Gun, 25ft Air-Cooled

Reliable Aluminum Welding with Miller XR-Aluma-Pro Lite

The Miller XR-Aluma-Pro Lite Push-Pull Gun (300948) is an expertly engineered solution for industrial aluminum welding applications. Designed to address the common challenges associated with feeding soft aluminum wire, this air-cooled gun system ensures consistent wire delivery and arc stability. Rated at 175 amps at a 60% duty cycle, it is perfectly suited for light industrial fabrication, sign manufacturing, and emergency vehicle repair. The gun features a direct connection design, making it instantly compatible with popular Miller power sources such as the Millermatic 252, Millermatic 255, Multimatic 255, and Millermatic 350P, as well as XR-Control wire feeders.

Optimized Feeding Performance

Feeding aluminum wire requires precision to prevent bird-nesting and erratic arcs. The XR-Aluma-Pro Lite addresses this with dual wire tension settings, allowing operators to switch between 4000 and 5000 series aluminum wires easily. This specificity ensures the drive rolls apply the exact amount of pressure needed for the alloy's hardness, resulting in the very best feeding performance. The system handles wire diameters from .030 to .047 inches (0.8 to 1.2 mm), covering the most common gauges used in aluminum fabrication.

Maintenance and Durability

Constructed for heavy-duty use, all internal components are built to last. A standout feature for maintenance teams is the replaceable feed cable liner. Unlike many competitors that require replacing the entire feed cable when the liner wears out, the XR-Aluma-Pro Lite allows for a simple liner swap. This design choice significantly reduces parts costs and service downtime. Additionally, the gun utilizes Bernard Centerfire consumables, which are renowned for providing superior gas coverage and extending consumable life, ensuring your operations run smoothly with fewer interruptions.
