198127 - Miller XR-15A Air-Cooled Push-Pull MIG Gun, 15ft, 200A

Industrial Grade Aluminum Welding Solution

The Miller XR-15A Push-Pull Gun (198127) is a heavy-duty, air-cooled MIG gun designed specifically for the rigorous demands of industrial aluminum welding. Engineered to work seamlessly with Miller XR-Control wire feeders, this pistol-grip gun resolves the common feeding issues associated with soft aluminum wires (such as 4043 and 5356 series) by utilizing a synchronized push-pull mechanism. This ensures consistent wire delivery, stable arc performance, and reduced bird-nesting, even over the 15-foot cable length.

Performance and Specifications

Rated for 200 Amps at 100% duty cycle, the XR-15A is built for continuous operation in manufacturing environments. It accommodates wire diameters ranging from .030" to 1/16", making it versatile for various material thicknesses. The gun features a 360-degree rotatable head tube, allowing welders to adjust the nozzle angle to access difficult joints without straining their wrists or compromising the wire path.

Maintenance and Durability

Miller has designed the XR-15A with maintenance efficiency in mind. The feed cable liner is fully replaceable, allowing operators to change just the liner rather than the entire cable assembly, significantly reducing long-term parts costs. The internal components are constructed for longevity, and the gun accepts standard, easy-to-change FasTip™ and Bernard® Centerfire™ contact tips, ensuring that consumables are readily available and quick to swap out during production.

Ergonomics and Control

The pistol-grip handle offers a natural hand position for vertical and out-of-position welding. When paired with a compatible XR-Control, the gun supports a trigger hold feature, which allows the operator to weld without continuously depressing the trigger, greatly reducing hand fatigue during long weld seams. This unit is an essential tool for industries ranging from shipbuilding and railcar manufacturing to general aluminum fabrication.
