OVERVIEW

Professional Conversion Kit for M-25 Guns

The Miller 1070116 Diffuser is a specialized conversion component designed specifically for the Miller M-25 MIG gun. If you are looking to modernize your torch without replacing the entire gun assembly, this diffuser is the solution. It effectively replaces the standard M-Series contact tip adapter (part number 169728) and the nozzle adapter (part number 169729), consolidating two parts into a single, high-performance unit. This simplification not only reduces the number of parts you need to stock but also introduces the benefits of the AccuLock MDX system to your welding operations.

The AccuLock MDX system is renowned for its "Fewer Parts, More Accuracy" philosophy. By installing this diffuser, you gain access to MDX nozzles and contact tips, which are designed for superior wire feeding and arc consistency. The diffuser features a robust taper connection that ensures a solid electrical path, minimizing resistance and heat buildup at the contact point. This results in a smoother arc and less troubleshooting during critical weld passes.

Installation Process:

  • Remove the old contact tip, diffuser, and nozzle from your M-25 gun.
  • Ensure the existing liner is in place; typically, no trimming is required if it was previously set up correctly.
  • Inspect the shock washer (169730) and replace it with a 4623RM nozzle insulator if it shows signs of damage.
  • Screw on the new AccuLock diffuser, followed by the MDX contact tip and nozzle.

This package includes two diffusers, ensuring you have the necessary components to maintain your equipment. It is an ideal choice for professional welders who demand reliability and ease of maintenance from their tools. By upgrading to the AccuLock platform, you ensure your M-25 gun remains a competitive and effective tool in your welding arsenal.
