The Miller Maxstar 280 DX provides up to 280 amps DC TIG and MMA welding output along with a smooth, stable arc. Advanced technologies, such as Pulse, reduce heat input, increase travel speeds and improve arc directional control. Auto-Line™ technology allows the machine to be connected to any mains voltage within the specified range. The Maxstar 280 DX addresses demands for precision fabrication, adding extended Pulse ranges for maximum DC capability. Exclusive Pro-Set™ technology eliminates guesswork by providing pre-set welding parameters. Designed for upgrade flexibility, a memory card port allows owners to download additional software when released, purchase product features from MillerWelds.com/tigsoftware and maximize their budgets by buying only the features they need. The Maxstar 280DX can offer air cooled capabilities or can be used as a water cooled system via the Cooler Power Supply (CPS), a dedicated receptacle that powers the Coolmate 1.3.
Auto-Line™ (Click for Demonstration) - Allows for any input voltage hookup (115–460 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.
Fan-On-Demand™ (Click for Demonstration) - power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through the machine.
Pulse - Pulsing can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion. DX models provide extended ranges.
Blue Lightning - High Frequency Arc Starter for non-contact arc initiation. More consistent arc starts compared to traditional HF arc starters. Greater reliability and no maintenance on solid state components. Preset parameters for tungsten sizes from 0.5 - 3.2mm provide optimized starting for applications from thick to micro thin. For unique applications, custom settings are programmable.
