Miller Electric Mfg. Co. added the Dynasty 800 and Maxstar 800 to its TIG welding lineup. The Dynasty 800 power source is AC/DC TIG and stick capable and rated for 1-in.-thick aluminum and steel. The DC TIG and stick capable Maxstar 800 is rated for up to 1-in.-thick steel. Meter calibration on the machines allows the digital meters to be accurately adjusted for certification. Standardized menus also help reduce welding operator training time and labor costs. The Cooler-On-Demand feature operates the machine’s auxiliary cooling system only when needed.
