225028 - Miller 225028 Water-Cooled TIG Adapter for Dynasty/Maxstar 700

Miller 225028 Water-Cooled TIG Torch Adapter

The Miller 225028 is a specialized TIG torch adapter engineered specifically for the heavy-industrial Maxstar 700 and Dynasty 700 welding power sources. These high-amperage machines utilize a robust 50mm thread lock-style receptacle to ensure maximum conductivity and safety at high outputs. This adapter bridges the gap between the machine's specialized output and standard water-cooled TIG torch power cables.

Designed for professional industrial environments, this adapter features a 50mm thread lock connector on the machine side and a standard 7/8-inch Left Hand Thread (LHT) female connection on the torch side. This configuration allows welders to connect a wide variety of common water-cooled torches—including the WP125, WP24W, WP25, WP20, WP18, WP12, CS310, CS410, WP22, and WP27 series—directly to the power source. The adapter facilitates both the electrical power transfer and the coolant flow required for these torches.

Reliability is paramount in high-amperage TIG welding. The thread lock design provides a mechanical security superior to standard friction-fit Dinse connectors, preventing accidental pull-outs or arcing caused by loose connections. This component is a genuine Miller Electric part, ensuring perfect fitment and material quality consistent with the performance requirements of the Dynasty and Maxstar 700 series.
