To improve DC TIG welding productivity and quality in industrial applications, Miller Electric Mfg. Co. has introduced its new Maxstar® 350 DC TIG/Stick inverter. Compared to the previous model, the Maxstar 350 TIG welder offers high speed pulsing capabilities (now up to 5,000 pulses per second, a ten-fold improvement), 50 amps more welding power, Auto-Line power management technology and a more robust design.
The Maxstar 350 delivers 5 to 350 amp output (300 A at 32 V, 60 percent duty cycle), weighs 135.5 lbs and features Auto-Line technology, allowing it to run from any input power, 208 to 575 V, single- or three-phase.
A single, full-featured Maxstar 350 model replaced three previous models. An easier-to-understand front panel controls basic TIG welding functions, while a secondary menu controls additional setup parameters and values. The Maxstar 350 is available as a stand-alone unit, as a TIGRunner package featuring the Coolmate 3.5 cooler and a TIGRunner package with cooler and Weldcraft water-cooled torch.
The Maxstar 350 enables users to adjust the number of pulses per second (PPS) from 0.1 to 5,000 PPS, control the amount of time each pu
