A welding transformer comprises magnetic cores connected one to another by a communication winding, which is wound above secondary winding and regulating winding and communication winding. Changing combination of connection of secondary, regulating winding and communication winding a wide range of regulation of welding current is obtained. Thereby, the welding transformer with minimal leakage flux is proposed that increases coefficient of efficiency and decreases mass and dimensions parameters. |
