OVERVIEW

Connect Your Water-Cooled Torch to Miller 700 Series Welders

If you are operating a Miller Dynasty 700 or Maxstar 700, you know these machines are built for serious power. To harness that power with your preferred water-cooled TIG torch, you need the Miller 225028 Adapter. This essential accessory converts the machine's heavy-duty 50mm thread lock receptacle into a standard connection point for your torch's power cable.

Many standard TIG adapters cannot handle the physical connection style of the 700-series machines. The Miller 225028 is designed explicitly for this purpose, featuring the unique thread-lock mechanism that screws securely into the front panel of your welder. This ensures that your connection stays tight, cool, and conductive, even when you are pushing the machine to its limits. On the other end, it accepts the industry-standard 7/8-inch Left Hand Thread found on most water-cooled TIG torch power cables (such as the WP-20 or WP-18 series).

Don't compromise your setup with makeshift solutions. Using the correct adapter protects your machine's terminals and ensures your coolant flows properly without leaks. Whether you are welding thick aluminum sections or precision aerospace parts, this adapter provides the reliable link between your power source and your torch. It is compatible with a broad range of torch models, including the Weldcraft WP-series and CS-series water-cooled torches.

Features:

  • Genuine Miller Electric component for guaranteed fit.
  • Enables use of standard water-cooled torches on 700-series machines.
  • Secure thread-lock design prevents disconnects.
  • Simple installation for quick torch changes.

FAQ

This adapter is specifically designed for the Miller Maxstar 700 and Miller Dynasty 700 welding power sources.

It is compatible with water-cooled torches such as WP125, WP24W, WP25, WP20, WP18, WP12, CS310, CS410, WP22, and WP27.

The Miller 225028 is designed exclusively for water-cooled TIG torch applications.

The adapter features a standard 7/8-inch - 14 Left Hand Thread (LHT) female connection for the torch power cable.

It uses a 50mm Thread Lock style connection, which screws into the receptacle on the Dynasty/Maxstar 700 for a secure fit.

No, the Dynasty 200 and 350 typically use standard Dinse connectors (50mm or 35mm) and do not require the Thread Lock style found on the 700 series.

No, this is the adapter only. The torch and power cable must be purchased separately.

The thread lock design provides a more secure mechanical and electrical connection capable of handling the high amperage output (up to 700A) without overheating or disconnecting.
