Miller Dynasty® 800 TIGRunner AC/DC TIG Welder, 208-600 V #907951001

The Dynasty® 800 TIGRunner mounts the 800-amp Dynasty 800 and a Coolmate™ PRO 4 water cooler on a four-wheel Runner cart. It welds aluminum and steel up to 1 inch thick and is rated at 600 amps at 60% duty cycle. Add coolant and a water-cooled torch to complete a high-amperage TIG station that moves around the shop as one unit.
