907553 - Miller Maxstar 280 DX TIG/Stick Welder 208-575V

Miller Maxstar 280 DX: Precision DC TIG and Stick Welding

The Miller Maxstar 280 DX is a premier solution for industrial welding applications requiring portability, power, and precision. Designed for professional fabricators, this DC TIG and Stick power source delivers up to 280 amps of output while weighing in at a manageable 47 pounds. It is engineered to handle a wide variety of materials, specifically excelling in steel and stainless steel applications with a material thickness capacity ranging from 0.004 inches up to 3/8 inch.

Auto-Line Power Management

One of the standout features of the Maxstar 280 series is the Auto-Line Power Management technology. This innovation allows the machine to connect to any input voltage within the 208-575 V range, single-phase or three-phase, without manual linking. This ensures that the welder remains operational and reliable even in facilities with dirty or unreliable power, making it an ideal choice for construction sites, shipboards, and diverse manufacturing environments.

Advanced DX Controls and QuietPulse

The "DX" designation indicates a suite of advanced features over the base model. This includes extended ranges for the sequencer, full trigger options, preflow, and pulser functions. A key highlight is the QuietPulse technology, which activates by altering the waveshape during DC pulse welding. This creates a slower, more fluid transition between background and peak amperage, significantly reducing audible noise and improving operator comfort during long shifts. Additionally, the Pro-Set feature eliminates guesswork by offering professional preset controls for Balance, Frequency, Pulse, and DIG parameters.

Stick Welding Capability

Beyond TIG welding, the Maxstar 280 DX is a formidable Stick welder. It features tailored arc control (DIG) that allows arc characteristics to be adjusted for specific electrodes, such as smooth-running 7018 or penetrating 6010 rods. The Hot Start adaptive control ensures positive arc starts without sticking, enhancing productivity and weld quality.

Note: This SKU (907553) includes the power source, adjustable shoulder strap, primary cord, and Dinse connectors. TIG torches and remote controls are sold separately or in specific packages.
