摘要： A high frequency arc welding apparatus is provided with one D.C. electrical source used for welding purpose and the other D.C. electrical source used for regeneration purpose. One variable impedance element is connected in circuit with the one D.C. electrical source and the other variable impedance element is connected in circuit with the other D.C. electrical source. Electrical energy stored by means of the one variable impedance element temporarily in one inductance provided inevitably in circuit with the one D.C. electrical source is regenerated in the other D.C. electrical source and is discharged in the other inductance provided in circuit with the other D.C. electrical source, by means of the other variable impedance element to be regenerated in the one D.C. electrical source.

摘要： A circuit for a high frequency arc welding apparatus which can control the welding current by keeping the peak value, that is the amplitude of the pulse component, of the welding current waveform constant and improve operating efficiency and reliability. The circuit includes a D.C. electrical source for welding and a condenser for regenerating. The welding current is controlled by controlling the voltage of the condenser. A low frequency switch periodically discharges the condenser to limit the voltage of the condenser and to transfer the stored energy of the condenser to the electrical source.
