用コンデンサを設けたアーク電源装置。[Claims for Utility Model Registration] On the primary side of the high-frequency transformer, an input side rectifier is provided to rectify the power supply AC to form an input DC, and is provided in series with the primary winding of the transformer to form the input DC. a high-frequency switching element for converting into high-frequency alternating current, and formed using a semiconductor rectifying element and a smoothing reactor on the secondary side of the transformer, rectifying the output alternating current of the secondary winding of the transformer;
An output-side rectifier that smooths and forms an output DC, and is inserted between the output-side rectifier and the output terminal, and is superimposed on the output DC at a frequency higher than the high-frequency AC at the time of welding, fusing, or starting lighting. An arc power supply device that is used for arc welding, fusing, or lighting an arc discharge lamp, and is equipped with a high frequency generator that generates high frequency and high voltage, and that accommodates each circuit section such as the rectifying sections, the transformer, and the switching element. An output cord for supplying the output DC and an input cord for the power AC are connected between the metal case and the input DC conduction path and between the case and the input side of the high frequency generator, respectively. The arc power supply device is provided with a small-capacity bypass capacitor that returns only the high-frequency high voltage leaked to the primary side through the case to the high-frequency generator.
