FIELD: electrical engineering. SUBSTANCE: transformer has magnetic circuit with primary and secondary windings, welding current regulator with control unit, reed relay, reed relay and stabilizing circuit. Safe voltage of idle run is achieved due to presence of additional lead of secondary winding and connection to it of in series circuit, made of reed relay and connected to regulator output reed relay. EFFECT: welding transformer is used in electrical engineering. 1 dwg
