300 CV Multiprocess Welder Fully Loaded Wireless

The Miller Dynasty 300 CV Multiprocess Welder is a fully loaded wireless package weighing just 55 pounds, which this maker states makes it one of the most portable machines in its class.

What it's for

Processes supported include stick welding, MIG, air carbon arc, and both AC and DC TIG with pulsed TIG control. Because it includes a CV and CPS welder, the primary use here is pairing the Dynasty 300 with a suitcase feeder, such as an ArcReach 8 or 12, for high-output wire feeding. Among its features: Auto-Line hookup across a wide voltage range, wind tunnel cooling with cooler-on-demand and fan-on-demand operation, pro-set parameters, a power-conserving sleep timer, firmware updates through a USB port, and a quick, high-frequency arc start with digital metering.

What to check before buying

This runs on single or three-phase power across multiple input voltages, so confirm your shop or jobsite supply matches before ordering. Exact duty-cycle and amperage figures vary between documentation for this package, so confirm your target amperage and duty cycle with us before planning a specific weld process around it.

What's included

The package ships with the Dynasty 300 power source, a Coolmate 1.3 cooler, a small runner cart, an ArcReach 12 feeder with a Bernard gun, two 50mm Dinse connectors, an 8-foot power cord with no plug attached, and a user manual. This unit carries a 3-year manufacturer's warranty.
