Circuit design of an a.c. stabilizer for welding transformers was proposed. A feature of the stabilizer is application of a resonance voltage increase in the secondary winding of the transformer to ensure repeated arc ignition after each current reversal. This enables reducing the power losses in the arc stabilizer, and ensuring efficient formation of high-voltage pulse packets for guaranteed breakdown of the arc gap. Application of the proposed arc stabilizer allows performance of welding operations with direct current electrodes at power supply from welding transformers without rectifiers. The stabilizer is designed for operation with transformers not fitted with electronic regulators, mainly with transformers with a magnetic shunt of TDM, STSH types. 12 Ref., 6 Fig.
