Miller Dynasty 300 TIG Welder with Cps (907818)

This Dynasty 300 with CPS is a dedicated AC/DC TIG and stick power source, built to weld up to 3/8 in material and carry a built-in 120-volt receptacle for a Coolmate water cooler. Duty cycle is rated 60% at 200A and 60% at 235A, and the unit weighs 58 lbs.

Arc control

Full AC waveform control and adjustable balance and frequency give it a wide range on aluminum, while Pro-Set stores preferred parameters for balance, frequency, pulse, and DIG so an operator can recall them instead of dialing in from scratch each time. Stick output adds tailored DIG control and an adaptive hot start, running smoothly from 7018 up to a stiffer 6010, and Stick-Stuck shuts off output automatically if an electrode sticks to the work.

Power and portability

Auto-Line lets it accept single-phase or three-phase input from 208 up to 575 volts without manual relinking, a useful trait on job sites with inconsistent power. A memory card data port supports software updates. It comes complete with the power source with CPS, a quick reference guide, an adjustable shoulder strap, an 8 ft primary cord, and two 50 mm Dinse connectors.

How heavy is it to carry? 58 lbs for the power source, with dual handles and the included shoulder strap.

Does it include a cooler? The CPS receptacle is built in; the cooler itself is not part of this listing.
