    Compared to similarly sized machines, the Maxstar 280 TIG welder delivers more power and provides the ability to weld metal up to 3/8-in thick—yet is significantly lighter, more portable, and uses less energy than machines of similar output capabilities.

    The DC TIG/Stick-capable Maxstar 280 is intended for industrial applications, construction, and heavy fabrication. Weighing in at 47 pounds, the Maxstar 280 delivers up to 280 amps of output power along with a smooth, stable arc to handle any job from small to large.

    Advanced technologies are incorporated to improve weld results, such as a pulse feature, which can reduce heat input, increase travel speeds, and improve arc directional control. Auto-Line technology provides added convenience in any job setting by allowing the machine to be hooked up to any input voltage within the specified range.

    The Maxstar 280 DX model addresses demands for precision fabrication, adding extended ranges for maximum DC capability. Exclusive Pro-Set technology eliminates guesswork by providing pre-set welding parameters. In addition, welding operators will experience ease-of-use through the control panel’s LED illuminated standby/power switch, which indicates whether the machine is unplugged or turned off at its main switch, turned on but in standby mode, or energized and ready to weld. 

    Designed for upgrade flexibility, a memory card port is included, allowing additional software to be downloaded and product features to be purchased from MillerWelds.com/tigsoftware. The memory card port allows for quick upgrades when software is released and helps owners maximize their budgets, purchasing only the features they need.

    The Maxstar 280 is designed for air-cooled and water-cooled TIG torches, and can be coupled with a torch specifically designed and rated for the output of the machine. With a Weldcraft W-280 (WP-280) water-cooled torch and the Coolmate 1.3 coolant reservoir options, a welding operator can purchase a complete water-cooled system solution.

    The advanced W-280 torch uses Super Cool technology for increased cooling efficiency, while the Coolmate reservoir uses an efficient fin-and-tube heat exchanger to provide a maximum cooling capacity of 13,000 Btu/hr.
