OVERVIEW

Precision and Power with the Miller Dynasty 280 DX

The Miller Dynasty 280 DX is a powerhouse of precision, designed to bridge the gap between heavy industrial manufacturing and delicate fabrication. Weighing in at only 52 pounds, this inverter-based AC/DC TIG and Stick welder offers exceptional portability without sacrificing the robust performance required for demanding jobs. Whether you are working on aerospace components, aluminum ship repair, or high-purity processing piping, the Dynasty 280 DX provides the control and reliability professional welders demand.

One of the standout features of this unit is the Auto-Line Power Management Technology. This innovation allows the machine to hook up to any input voltage from 208 to 575 V, single-phase or three-phase, with no manual linking required. This makes the Dynasty 280 DX an ideal solution for job sites with dirty or unreliable power, ensuring consistent arc performance regardless of voltage fluctuations. Additionally, this model (907514) comes equipped with the Cooler Power Supply (CPS), an integrated 120-volt dedicated-use receptacle designed to power the Coolmate 1.3 water cooler. The CPS is synchronized with the power source, activating the receptacle only when the machine is on, which helps prevent torch failure due to lack of coolant flow.

For operators who need efficiency and ease of use, the Dynasty 280 DX features Pro-Set technology. This eliminates the guesswork when setting weld parameters by offering preset controls for Balance, Frequency, Pulse, and DIG. Simply select the feature and adjust until Pro-Set appears on the display to access professionally optimized settings. The machine also includes a front panel memory card data port, allowing you to easily update software and expand product features as Miller releases new capabilities, ensuring your investment remains cutting-edge for years to come.

Durability is built into every aspect of the design. Miller's Wind Tunnel Technology protects internal electrical components from airborne contaminants like dust and dirt, significantly extending product life. Coupled with the Fan-On-Demand cooling system, which operates only when needed, the machine reduces noise, energy consumption, and the intake of contaminants. The Dynasty 280 DX is the ultimate tool for welders seeking versatility, portability, and uncompromising quality in one package.

FAQ

The Dynasty 280 DX features Auto-Line technology, allowing it to accept any input voltage from 208 to 575 V, in either single-phase or three-phase, without manual linking.

No, this specific SKU (907514) includes the power source with CPS, a cord, a strap, and connectors. TIG torches, foot pedals, and coolant systems are sold separately or in different packages.

CPS stands for Cooler Power Supply. It is an integrated 120V receptacle on the machine dedicated to powering a Coolmate water cooler. It ensures the cooler turns on with the welder, preventing torch failure.

Yes, the Dynasty 280 DX is an AC/DC machine, making it excellent for welding aluminum and magnesium (AC) as well as steel and stainless steel (DC).

The DX model offers advanced AC waveforms (Square, Soft Square, Sine, Triangular) and wider ranges for balance and frequency control, whereas the standard model has fewer waveform options.

The power source itself weighs approximately 52 lbs (23.6 kg), making it highly portable for an industrial machine.

The machine is rated at 235 Amps at 19.4 Volts with a 60% duty cycle when using 3-phase power for TIG welding.

Yes, the Dynasty 280 DX supports Stick (SMAW) welding with features like Hot Start, DIG control, and Stick-Stuck protection.
