OVERVIEW

Precision AC/DC TIG Welding Power Source

The Miller Dynasty 300 (907818006) represents the pinnacle of industrial TIG welding technology, designed to replace the legendary Dynasty 280 with enhanced power and interface capabilities. This machine is engineered for the most demanding applications in aerospace, heavy fabrication, and precision manufacturing. With a wide amperage range of 1 to 300 amps, it provides the versatility needed to weld everything from thin-gauge aluminum to thick steel sections with absolute control.

At the core of the Dynasty 300 is Miller's exclusive Auto-Line™ Power Management Technology. This allows the machine to hook up to any input voltage within the 208V to 600V range, single-phase or three-phase, without manual linking. This flexibility ensures consistent performance regardless of

FAQ

The Dynasty 300 is the successor to the Dynasty 280, offering a higher amperage output (300A vs 280A) and an updated user interface for easier navigation and setup.

CPS stands for Cooler Power Supply. It is an integrated 120V receptacle on the machine designed to power a dedicated water cooler, such as the Coolmate 1.3.

No, this SKU (907818006) is for the power source only. Torches, foot controls, and water coolers are sold separately or as part of a 'Runner' package.

Thanks to Auto-Line technology, the Dynasty 300 accepts any input voltage from 208V to 600V, single-phase or three-phase, without manual linking.

Cam-Lok connectors are heavy-duty, twist-lock cable connectors often used in industrial settings for secure, high-amperage connections, offering durability superior to standard plug-in types in rough environments.

Yes, the Dynasty 300 is an AC/DC machine, making it excellent for welding aluminum (AC) as well as steel and stainless steel (DC).

The Dynasty 300 has a duty cycle of 60% at 250 Amps, allowing for extended welding periods at high amperage.
