Abstract
PURPOSE:To generate the high frequency soon after the polarity inversion, and to make superior the stability and starting characteristics of the arc, by generating the high frequency starting signal through detecting the level of output voltage of the welder. CONSTITUTION:The polarity inversion of the arcing voltage is detected by the detector 8 for the output voltage of the welder, and the high frequency generator 2 is actuated by the high frequency starting signal generator 7, and then, the high frequency current is overlapped on the output current through the coupling coil 3 only when the arc is reignited. The full-wave rectified waveform of output voltage of the welder is obtained on the anode side of diodes 10, 11, and the interval of ON and OFF of the transistor 22 is determined by the split ratio of resistors 16, 17. The transistor 23 is put ON only when the transistor 22 is put OFF, and actuates the light emission diode 15 so as to ignite the photo-thyristor. Thus the phase of generated high frequency can be freely controlled depending on the split ratio of resistors 16, 17, and is set within the range from the phase at which the output voltage of the welder becomes about 30V after making zero-crossing to 90 degrees.
