OVERVIEW

Genuine Miller Replacement Parts for Spoolmatic Guns

Maintain the precision and reliability of your aluminum welding setup with the Miller 148489 Anti-Turn Flat Washer. Designed exclusively for the industry-standard Spoolmatic 15A and 30A spool guns, this component plays a critical role in the internal assembly of the feeder gun. Unlike standard hardware store washers, this specific part features an anti-turn design and a substantial thickness of 0.500 inches (1/2 inch), effectively functioning as a structural spacer within the gun's mechanism.

In high-amperage MIG welding applications, particularly when using soft aluminum wire, the stability of the gun components is paramount. This washer ensures that internal parts remain aligned and do not rotate under the torque and vibration of operation. With an inner diameter of 0.380 inches and an outer diameter of 0.620 inches, it provides a precise fit that prevents play and potential damage to the gun barrel or contact assembly.

Josef Gas supplies this part as a package of two, allowing you to repair your current equipment while keeping a spare on hand for future maintenance. Using genuine Miller Electric parts guarantees that your equipment remains within factory specifications, ensuring consistent wire feeding and arc performance. Whether you are performing routine maintenance or a complete overhaul of your Spoolmatic system, trust in OEM components for the best results.
