とする高周波誘導加熱溶接装置。 The voltage regulator converts alternating current into voltage-controlled direct current, applies this direct current voltage to an oscillation tube, and supplies high-frequency welding current to the welding load through a work coil that resonates with the alternating current from this oscillation tube. A signal corresponding to the welding power is obtained by multiplying an addition unit that adds the welding power set value and its correction value by a voltage detection signal and a current detection signal corresponding to the plate voltage and plate current of the oscillation tube, respectively. It has a multiplication section that calculates, and a power control amplification section that amplifies the deviation between the output signal from the addition section and the output signal from the multiplication section, and adjusts the voltage based on the output signal from the power control amplification section. A high frequency induction heating welding device characterized in that the plate voltage of the oscillation tube is controlled through the section.
