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.
