907819001 - Miller Dynasty 300 Multiprocess TIGRunner AC/DC Welder Package

Complete Multiprocess TIG Welding Solution

The Miller Dynasty 300 Multiprocess TIGRunner is the definitive answer for professional fabricators who demand versatility without compromise. This comprehensive package combines the advanced Dynasty 300 power source with the Coolmate 1.3 water cooler and a durable Small Runner cart, creating a mobile, high-performance welding station ready for the most rigorous industrial environments. Whether you are working on precision aerospace components, heavy aluminum fabrication, or pipe and tube welding, this machine delivers the arc quality and control Miller is famous for.

At the heart of this system is the Dynasty 300's multiprocess capability. While renowned for its superior AC/DC TIG performance, this unit also excels at Stick welding and Air Carbon Arc gouging. Furthermore, it features CV output, allowing for MIG welding when paired with a compatible voltage-sensing wire feeder (such as the ArcReach or SuitCase series). This flexibility means a single machine can handle a vast array of jobs, reducing the need for multiple power sources on the shop floor.

The user interface is designed for efficiency. The large 4.5-inch LCD display provides clear, informative feedback, while the Pro-Set feature eliminates guesswork by offering professional-grade preset parameters for Balance, Frequency, Pulse, and DIG. For advanced users, the machine offers granular control over waveforms (Square, Sine, Triangular) and independent AC amplitude, allowing you to tailor the arc to the specific joint geometry and material thickness. The included Coolmate 1.3 ensures your torch stays cool during high-amperage applications, utilizing Cooler-On-Demand technology to run only when necessary, thereby reducing noise and airborne contaminants.

Reliability is built into every aspect of the Dynasty 300. Miller's Auto-Line technology allows the machine to hook up to any single or three-phase input voltage from 208 to 600 V automatically, making it perfect for shops with fluctuating power or varying job site requirements. With the ability to save and recall weld settings via Program Memory and update software through the front USB port, this TIGRunner package is a future-proof investment for any serious welding operation.
