907537002 - Miller Dynasty 280 TigRunner AC/DC Water-Cooled TIG Welder System

Industrial AC/DC TIG Welding System

The Miller Dynasty 280 TigRunner (SKU: 907537002) is a premium industrial welding package designed for precision fabrication and heavy-duty manufacturing. This system integrates the powerful Dynasty 280 power source with the Coolmate™ 1.3 water cooler and a durable Small Runner Cart, providing a mobile, ready-to-weld station for high-performance TIG and Stick applications. Engineered with Miller's proprietary Auto-Line™ Power Management Technology, this machine allows for connection to any input voltage hookup (208–575 V, single- or three-phase) with no manual linking required, ensuring consistent performance even on dirty or unreliable power.

The unit features a Cooler Power Supply (CPS), a dedicated 120-volt receptacle integrated into the power source to run the Coolmate 1.3. This intelligent design ensures the cooler is activated by the power switch, preventing torch failure due to lack of coolant flow. The Dynasty 280 offers a wide amperage range of 1 to 280 A (DC TIG) and is capable of welding materials from 0.004 inches up to 3/8 inch thick. It supports advanced AC TIG features including Balance Control for adjustable oxide removal and Frequency Control to tailor the arc cone width, essential for high-quality aluminum and magnesium welding.

Reliability is central to the design, utilizing Wind Tunnel Technology™ to protect internal electrical components from airborne contaminants and Fan-On-Demand™ to operate the cooling system only when necessary. This reduces noise, energy consumption, and the intake of abrasive particles. The front panel includes a memory card data port for easy software updates and feature expansion. With a rated output of 235 A at 60% duty cycle, the Dynasty 280 TigRunner is built to handle the rigorous demands of the aerospace, ship repair, and pipe fabrication industries.
