Miller Dynasty 300 CV Multiprocess Welder W/Cps Tigrunner (907819001)

This Dynasty 300 CV with CPS adds a TIGrunner setup: a small cart plus a Coolmate 1.3 cooler riding alongside the same power source used in the standalone version. Pairing it with a feeder such as an ArcReach 8 or 12 (not included) turns it into a MIG wire-feeding setup.

What it does on its own

Without the feeder it still handles pulsed TIG, stick, and air carbon arc gouging on the same range of metals: aluminum, mild steel, stainless, and titanium. Rated output is 280 amps, with duty cycle at 60% on three-phase power at 200A and 60% on single-phase at 180A. The power source itself weighs 55 lbs; the cart and cooler add to that for transport.

On the cart

Auto-Line accepts single or three-phase power anywhere from 208 to 575 volts without manual relinking. Software updates load through a front-panel USB port, TIG arc starts stay non-contact thanks to the high-frequency circuit, and the sleep timer plus on-demand fan and cooler cut down on noise and wasted power between passes.

What's included with the cart? The Dynasty 300 power source, the Coolmate 1.3 cooler, the small runner cart, a power cord (8 ft, no plug), a pair of 50 mm Dinse connectors, and a user manual.

Is the wire feeder part of this package? No, a suitcase feeder for MIG is a separate purchase either way.
