198129 - Miller XR-15W Water-Cooled Push-Pull MIG Gun, 15ft, 400A

High-Performance Water-Cooled Aluminum Welding Solution

The Miller XR-15W Pistol Grip Gun (SKU: 198129) is a robust, water-cooled push-pull MIG gun engineered specifically for heavy industrial aluminum fabrication. Designed to operate in conjunction with Miller XR-Control wire feeders, this system provides a reliable solution for feeding soft alloy wires, such as aluminum, which are prone to buckling and birdnesting in standard push-only systems. The gun features a 15-foot cable assembly equipped with quick disconnects, facilitating rapid equipment changes and simplified maintenance in dynamic production environments.

Rated at 400 Amps, the XR-15W utilizes water cooling to maintain optimal operating temperatures during high-duty cycle applications. This cooling capability is essential for preserving consumable life and ensuring operator comfort during prolonged welding sessions. The gun is compatible with wire diameters ranging from .030 to 1/16 inch (0.8 to 1.6 mm), making it versatile for various material thicknesses found in shipbuilding, railcar manufacturing, and general aluminum fabrication. The wire feed speed capability ranges from 70 to 875 IPM, accommodating both precision work and high-deposition filling.

Maintenance and Ergonomics

Miller has designed the XR-15W with serviceability in mind. The feed cable liner is fully replaceable, allowing operators to change only the liner rather than the entire cable assembly, significantly reducing long-term parts costs and service downtime. The gun also features a heavy-duty construction with internal components built for lasting precision. Ergonomically, the pistol-grip design offers excellent balance, and the integrated trigger hold function helps reduce hand fatigue by allowing the welder to maintain the arc without continuously depressing the trigger—a critical feature for long seam welds.

Versatile Configuration

To address access challenges in complex assemblies, the XR-15W includes a threaded, quick-change head tube that can rotate 360 degrees. This allows the welder to orient the nozzle for optimal joint access without straining the cable or the operator's wrist. The front end accepts standard FasTip™ and Bernard® Centerfire™ contact tips, ensuring broad compatibility with readily available consumables. Whether utilized in pulsed MIG or standard CV MIG processes, the Miller XR-15W delivers the consistency and durability required for professional industrial environments.
