OVERVIEW

Restore Your MDX Gun Performance

The Miller 2200169 Power Pin Assembly is a critical replacement part designed exclusively for the Miller MDX™-100 and MDX™-250 series MIG guns. Over time, the power pin on your welding gun can become worn, damaged, or corroded, leading to poor electrical conductivity, erratic arcs, or gas leaks. Replacing this component ensures your equipment operates at peak efficiency, maintaining the high standards expected from Miller Electric products.

Precise Fit and Function

Engineered to exact factory specifications, this power pin assembly guarantees a perfect fit into the back end of your MDX gun. It serves as the primary interface between the gun and the welding machine, facilitating the transfer of welding current, shielding gas, and the welding wire itself. A secure and clean connection here is vital for smooth wire feeding and stable arc characteristics.

Important Installation Note

Please note that this assembly is the power pin body only. To complete the installation, you must pair it with a wire-specific power pin cap, which is sold separately. This modular design allows you to tailor the gun to your specific wire diameter:

  • Use part 2200170 for wire sizes .023" to .030".
  • Use part 2200171 for wire sizes .030" to .045".

Whether you are performing routine maintenance or repairing a damaged gun, trust genuine Miller parts from Josef Gas to keep your fabrication projects moving forward without interruption.

FAQ

This power pin assembly is designed specifically for the Miller MDX-100 and MDX-250 MIG guns.

No, the power pin cap is sold separately. You need to select the cap based on your wire size.

For .030" wire, you can use either the 2200170 (range .023-.030) or the 2200171 (range .030-.045), depending on your specific setup preference, though 2200170 is often standard for smaller wires.

Yes, this is a genuine Miller Electric replacement part, number 2200169.

The power pin may need replacement if the threads are stripped, the O-rings are damaged causing gas leaks, or if there is electrical arcing damage affecting conductivity.

Yes, it fits the MDX-250 series, including the EZ-Select models, as they share the same back-end architecture.

It is primarily constructed of brass to ensure high electrical conductivity and durability.

No, this pin is specific to the MDX series geometry. Other Miller guns (like M-series or Bernard) use different power pins.
