Abstract

PURPOSE:To obtain a cleaning action with a simple structure and to enable a sufficient penetration depth by forming a power source part by the combination of three sets of six diodes and four switching means. CONSTITUTION:The cathode of diodes 3-5 is commonly connected to the + terminal of a main power source 1 and the anode of diodes 6-8 is commonly connected to the - terminal of the main power source. The anode of the diode 3 and the cathode of the diode 6, the anode of the diode 4 and the cathode of the diode 7 and the anode of the diode 5 and the cathode of the diode 8 are respectively connected. Switching element 9-12 is respectively connected in parallel to diode 4-7 to execute ON/OFF control by a control circuit 13. A 1st electrode 15 and a 2nd electrode 16 surrounding it are approached to the material 14 to be welded and a shielding gas is blown from a shielding nozzle 17. A high AC voltage is generated by an arc starter 18 to generate an arc between both electrodes 15, 16.
