227404 - Miller XR Aluma-Pro Replacement Handle Kit

Maintain Equipment Integrity with the Miller 227404 Handle Assembly

In high-precision aluminum welding environments, the condition of your equipment is directly tied to the quality of your output. The Miller 227404 Handle Assembly is the genuine OEM replacement housing designed specifically for the XR Aluma-Pro Series push-pull MIG guns. These guns are sophisticated tools engineered for feeding soft aluminum wire over long distances, and the handle assembly plays a critical role in protecting the internal drive mechanisms, trigger leads, and gas conduits.

Over time, the harsh realities of industrial manufacturing—drops, impacts, and constant thermal cycling—can compromise the structural integrity of the gun's handle. A cracked or damaged handle not only affects the welder's ergonomic comfort but can also expose sensitive internal components to shop dust, metal shavings, and moisture. This replacement kit (SKU: 227404) provides a complete solution, including both the left and right handle halves along with the necessary mounting screws to secure them firmly. By using genuine Miller parts, you ensure that the internal cavities align perfectly with the gun's mechanical components, preventing pinching of wires or misalignment of the wire liner.

For maintenance managers and welding engineers, keeping these assemblies in stock is a proactive measure to minimize downtime. Swapping out a damaged handle is a quick repair that restores the gun to factory specifications without the need for a complete torch replacement. The high-impact composite material is formulated to resist the heat and abuse typical of heavy fabrication, shipyard work, and trailer manufacturing. Ensure your fleet of XR Aluma-Pro guns remains safe, compliant, and comfortable for your operators with this exact-fit replacement assembly.

Technical Specifications and Fitment

This assembly is strictly compatible with the XR Aluma-Pro line. It is not designed for the pistol-grip style XR guns or standard MIG guns. The kit includes all necessary housing components to rebuild the grip section of the torch. Installation requires standard hand tools and can be performed on the shop floor, allowing for rapid turnaround and return to service.
