951000005 - Miller Dynasty 400 Complete TIG Runner Package with Foot Control

Miller Dynasty 400: The Ultimate TIG Runner Package

Take your welding capabilities to the next level with the Miller Dynasty 400 Complete Package. This heavy-duty AC/DC TIG and Stick welding system is engineered for the most demanding industrial environments, offering 400 amps of welding power in a compact, energy-efficient inverter design. The package includes everything a professional welder needs to start fabricating high-quality parts immediately: the power source, water cooler, running gear, and foot pedal control.

Unrivaled Arc Stability and Control

The Dynasty 400 is famous for its exceptionally smooth and precise arc, capable of welding exotic materials with ease. It features Blue Lightning™ High Frequency Arc Starter technology, which ensures consistent non-contact starts every time, eliminating tungsten contamination and improving weld quality. For DC TIG applications, the high-speed pulse controls (up to 5000 pulses per second) add incredible arc stability, reduce heat input, and minimize warpage—critical factors when working with stainless steel and thin alloys.

Total AC Arc-Shaping Capabilities

Welders know that aluminum requires specific arc characteristics. The Dynasty 400 puts total control in your hands. You can adjust the AC balance to fine-tune the cleaning action versus penetration, and modify the AC frequency to narrow or widen the arc cone. The machine also supports independent amplitude control, meaning you can run higher EN amperage for penetration while keeping EP amperage lower to preserve your tungsten. This level of adjustability results in higher travel speeds and superior weld aesthetics.

Built for the Shop Environment

This package is built around the needs of the professional shop. The Coolmate™ 3.5 water cooler ensures your torch stays cool during high-amperage runs, extending consumable life and operator comfort. The integrated Cooler Power Supply (CPS) simplifies cable management by eliminating the need for an extra wall plug for the cooler. The entire system is mounted on a durable runner cart that accommodates a gas cylinder, making it easy to move the station around the workshop.
