Miller debuts new portable welders

Miller Electric Mfg. Co. has introduced the Dynasty 280 and Maxstar 280 TIG welders, which provide the ability to weld metal up to 3/8-inch thick — yet are lighter, more portable and use less energy than machines of similar output capabilities, according to company officials.

Weighing in at 52 and 47 pounds, the Dynasty 280 and Maxstar 280 deliver up to 280 amps of output power, according to company officials. 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, company officials explained.

MillerOn all models, exclusive Pro-Set technology eliminates guesswork by providing pre-set welding parameters, company officials said. In addition, welding operators will experience ease-of-use through the control panel’s LED illuminated standby/power switch which clearly 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 on all models, allowing additional software to be downloaded and product features to be purchased from The memory card port allows for quick upgrades when software is released and helps owners maximize their budgets, purchasing only the features they need, company officials said.

The Dynasty 280 and Maxstar 280 — both designed for air-cooled and water-cooled TIG torches — can be coupled with a torch specifically designed and rated for the output of the machine. With a new 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.
