SYNERGIC TIG WELDING SYSTEM

摘要

There is provided an improved TIG welder comprising a power source for performing an AC TIG welding process across an electrode and a workpiece wit h a controller for creating an AC waveform. The controller having a synergic inp ut device with an input for receiving a signal level representing a desired set curren t for the welding process and an output signal determining an aspect of the waveform a nd representing a non-linear relationship between peak positive current and pea k negative current for certain desired set welding currents
