907538 - Miller Maxstar 280 TIG/Stick Welder with CPS (208-575V)

Powerful Portability for TIG and Stick Welding

Take your welding capabilities to new heights with the Miller Maxstar 280 TIG/Stick Welder. Whether you are working in the shop or out in the field, this machine delivers the industrial-grade performance you expect from Miller in a package that weighs less than 50 pounds. Gone are the days of hauling heavy transformers; the Maxstar 280 combines an energy-efficient inverter design with a compact form factor, making it easy to carry with the included shoulder strap or dual handles.

One of the standout features of this welder is the Auto-Line™ technology. You no longer need to worry about matching your machine to the shop's power supply. The Maxstar 280 automatically adjusts to any input voltage between 208V and 575V, single or three-phase. This flexibility is a game-changer for contractors who move between different job sites. Additionally, the integrated Cooler Power Supply (CPS) simplifies your setup if you run a water-cooled torch. By plugging your Coolmate™ 1.3 directly into the machine, you ensure your cooling system runs whenever the welder is on, protecting your equipment and extending torch life.

Miller has packed this unit with operator-friendly features to help you weld smarter. The Pro-Set™ feature allows you to dial in professional-grade settings instantly, giving you the confidence of pre-set controls for speed and convenience. For Stick welding, you get advanced arc control that handles everything from 6010 to 7018 electrodes with ease. With its durable construction, Wind Tunnel Technology™ to keep out dust, and Fan-On-Demand™ cooling to reduce noise and energy use, the Maxstar 280 is built to withstand the toughest environments while delivering precise, high-quality welds every time.
