Miller Electric Mfg. Co. (Appleton, Wisconsin) has introduced the new Dynasty 280 DX with CV, a multiprocess welder capable of AC/DC TIG, MIG and stick welding. Weighing just 55 pounds, this portable machine is suitable for the shop or jobsite for applications, including shipbuilding, construction, precision fabrication, heavy fabrication, pipe and tube fabrication, and maintenance and repair.

“This machine is where portability meets multiprocess for a wide range of applications,” said Brian Bellile, product manager, Miller Electric Mfg. Co. “The Dynasty 280 DX with CV is the most versatile, portable machine in its class.”

With the Dynasty 280 DX with CV, welding operators can TIG weld 0.012 to 3/8-inch aluminum and 0.004 to 3/8-inch steel. The machine offers superior arc performance and the ability to TIG weld with AC waveforms, including advanced squarewave, soft squarewave, sine wave and triangular wave.

Offering multiprocess versatility, the CV output of the machine delivers MIG welding capabilities when paired with a SuitCase® X-TREME™ voltage-sensing feeder. The feeder is powered off the arc voltage of the power source and can run both solid and flux-cored wires.

The Dynasty 280 DX with CV delivers up to 280 amps for welding and includes Auto-Line™ technology, which allows for any input voltage hookup from 208 to 575 volts with no manual linking. This provides convenience for any job setting and is ideal for applications where there is dirty or unreliable power.

In addition, the machine uses high frequency (HF) on starts only to eliminate HF interference issues during welding. Blue Lightning™ high-frequency arc starter technology provides non-contact arc initiation, resulting in more consistent arc starts and greater reliability compared to traditional HF arc starters.

Operators can make precision adjustments using the machine’s all-digital controls, for greater quality control and repeatability. The Dynasty 280 DX with CV also includes Pro-Set™ technology, which eliminates the guesswork when setting weld parameters. Operators can simply select the feature and adjust until Pro-Set appears in the display.
