907717002 - Miller Dynasty 400 CE TIG/Stick Inverter Welder

Advanced Precision for Industrial Fabrication

The Miller Dynasty 400 (CE) is a premier TIG and Stick welding power source designed to meet the rigorous demands of heavy fabrication, aerospace, and pipe manufacturing. Engineered with Miller’s proprietary Auto-Line™ power management technology, this inverter-based machine allows for seamless hookup to any input voltage ranging from 208 to 575 V without the need for manual linking. This flexibility ensures consistent, reliable performance even in environments with dirty or unreliable power, making it an indispensable asset for international and varied job site applications.

At the core of the Dynasty 400 is a suite of advanced arc control technologies. The Tailored Arc Control (DIG) allows welders to customize arc characteristics to suit specific electrode types and applications, ensuring optimal penetration and bead profile. The machine also features QuietPulse™ technology, which activates during DC pulse welding to create a smoother transition between background and peak amperage. This significantly reduces the audible noise generated by the arc, improving the working environment for the operator without compromising weld quality. Furthermore, the adjustable arc cone width provides enhanced directional control, critical for precision work in tight corners or on complex geometries.

Durability and ease of maintenance are built into the design with Wind Tunnel Technology™. This internal airflow system protects electrical components and PC boards from airborne contaminants like dust and dirt, extending the lifespan of the unit. The Cooler Power Supply (CPS) is an integrated 120-volt dedicated-use receptacle for the Coolmate™ 3.5, ensuring your cooling system is powered directly by the welder. With software update capabilities and the ability to transfer settings between units, the Dynasty 400 represents a future-proof investment for high-level industrial welding operations.
