Tig/Stick Welding Power Source

Miller has developed a Maxstar/Dynasty 350/700 TIG/stick welding power source that allows for any input voltage hookup (208-575 V) with no manual linking, providing convenience in any job setting. The welding power source is an ideal solution for dirty or unreliable power and features 120 V auxiliary power receptacle for water cooling system or small tools, wind tunnel technology that protects internal electrical components from air-borne contaminates, extending the product life. Other features of the welding source include fan-on-demand (power source cooling systems operate only when needed, reducing noise, energy use and the amount of contaminates pulled through the machine); programmable start parameters (that allow independent starting conditions based on process and memory selections (amperage and time); and auto-post flow that calculates the length of post flow time based on the amperage setting. This eliminates the need to independently set the post flow time for different amperages. This feature preserves tungsten and prevents porosity. The DC TIG features include exceptionally smooth and precise arc for welding exotic material, high-speed TIG pulse controls with a pulse frequency that is capable of pushing 5000 pulses per second. Pushing adds arc stability, reduces heat input and warpage and can increase travel speeds. Advanced squarewave, soft squarewave, sinewave and triangular AC waveform selection allows the arc to be optimised for the application. All AC waveform use HF for arc start only and not for continuous AC stabilisation, 20-400 Hz output AC frequency can focus the arc for increased directional control and arc stability.
