Miller Dynasty 300 CV Multiprocess Welder, ArcReach 12 Feeder, Cooler and Cart
The Miller Dynasty 300 CV multiprocess welder package combines the Dynasty 300 CV with CPS, an ArcReach 12 suitcase feeder with a Bernard MIG gun, a Coolmate 1.3 cooler and a small runner cart. It covers MIG, AC/DC TIG, pulsed TIG, stick and air carbon arc, and Auto-Line input accepts 208-600 V, single- or three-phase.
The CV output lets the Dynasty drive a suitcase feeder for high-output wire feeding, and the included ArcReach 12 with Bernard gun completes that MIG (GMAW) setup. Output spans 2-300 A on AC and 1-300 A on DC, AC TIG (GTAW) covers material from 0.012 to 3/8 in. thick, and stick (SMAW) capacity reaches 1/4 in. 6010, 7/32 in. 7018 and 3/16 in. 7024 electrodes.
Blue-Lightning high-frequency arc starts, pulse, Pro-Set parameters and digital meters are built in, and a 120 V Cooler Power Supply (CPS) receptacle powers a cooler, with cooler-on-demand and fan-on-demand running cooling only when needed. Wind Tunnel Technology, a sleep timer and USB software updates are standard, the generator requirement is 12.5 kW, and two 50mm Dinse connectors, an 8 ft power cord without plug and the user manual are included.
