Genuine Miller 2200362 Power Pin Cap for MDX Series

Maintain the peak performance of your Miller MDX MIG gun with the genuine Miller 2200362 Power Pin Cap. This essential component is designed specifically for MDX series guns utilizing the LM3 liner system. It plays a critical role in the back-end assembly of your torch, securing the liner in place to ensure smooth and consistent wire feeding. Designed to accommodate wire diameters from .035" to .045", this cap is a direct replacement for the original part found on your equipment.

Using genuine Miller OEM parts is crucial for the longevity of your welding setup. The 2200362 cap is manufactured to precise tolerances, ensuring a perfect seal and secure fitment that aftermarket alternatives often cannot match. A loose or damaged power pin cap can lead to liner movement, gas leakage, and erratic arc stability, all of which compromise weld quality. By replacing worn components with authentic Miller parts, you ensure that your gas coverage remains consistent and your wire feeds without interruption.

This power pin cap is compatible with Miller MDX-100 and MDX-250 MIG guns commonly found on Millermatic machines. Whether you are performing routine maintenance or repairing a damaged connection, this part installs easily onto the power pin assembly. It is constructed from durable materials capable of withstanding the thermal cycles and mechanical stress typical of industrial welding environments.
