Dynasty 300 Complete Package W/Wireless

This AC/DC TIG and stick package ships complete with a wireless foot control, a Coolmate 1.3 cooling unit, four one-gallon bottles of coolant, a small running cart, and a torch kit, aimed at shops that want a ready-to-weld setup out of the box rather than sourcing accessories separately. It is rated 280 amps and 244 pounds.

Power input flexibility

An auto-line power-management system lets the machine connect to either single-phase or three-phase input from 208 to 575 volts without manual rewiring inside the case, which matters for shops that move between job sites with different available service. A built-in 120-volt receptacle, switched with the main power switch, is meant to run the Coolmate coolant pump and help protect the torch from running dry.
