Maxstar 150 DC stick/TIG inverter

Miller Electric Mfg. Co.'s new Maxstar® 150 Series of inverters weigh just 13.7 pounds, have a 5- to 150-amp welding range, provide best-of-class arc performance, and run on 115v to 230v AC primary power. The Maxstar 150 is available in three models: S (Stick-only), STL (Stick/TIG Lift-Arc™ start) and STH (Stick/TIG high frequency or Lift-Arc™ start). All models have stick output of 150 amps at 30 percent duty cycle using 230v AC power. This enables nearly unlimited welding with a 1/8-inch diameter stick electrode, which covers approximately 80 percent of all stick applications.
