Miller Electric Mfg. Co. offers the Maxstar 350 DC TIG/Stick inverter. It offers high speed pulsing capabilities (up to 5,000 pulses per second), Auto-Line power management technology and a robust design. The Maxstar 350 delivers 5 to 350 amp output and weighs 135.5 lbs. 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 pulse cycle spends at peak amperage from 5 to 95 percent of total cycle time and set the background or "low" current pulsing value to between 5 to 99 percent of peak amperage. Typical applications include stainless steel, nickel alloys and other metals where excess heat can lead to warping or degrading metallurgical composition (e.g., carbide precipitation). In automation applications, which require maximum travel speeds, pulsing at frequencies beyond 500 PPS can further enhance arc stability and concentration.
