Maxstar 350 TIG Welder, DC, 1- & 3- Phase, 5-350 A

The Maxstar 350 has exceptional performance and is considered the finest DC TIG/Stick machine available that provides outstanding arc performance and product reliability. The DC TIG features an exceptionally smooth and precise arc and high-speed DC TIG pulse controls. The DC Stick features the tailored arc controls (DIG) and the Hot Start. Both come with Auto-Line, which allows for any input voltage hook-up (208-575 V) with no manual linking, providing convenience in any job setting. 120 V auxiliary power receptacle for cooling system or small tools. Program memory features 9 independent program memories that maintain/save your parameters. Programmable start parameters allow the operator to independently set starting conditions based upon process and memory selections (amperage and time). Superior TIG/Stick arc performance on all input voltages. Even on the difficult to run electrodes like E6010. HF arc starting provides non-contact arc starting that eliminates tungsten or material contamination. Auto-Postflow calculates the length of postflow time based on the amperage setting. This eliminates the need to independently set the postflow time for different amperages. This feature preserves your tungsten and prevents porosity. And also features the Fan-On-Demand, Wind Tunnel Technology, and LVC Line Voltage Compensation technology from Miller.

Maxstar 350 provides the basic features that are required for most DC TIG or Stick welding applications.
