VDU-1202 welding rectifier is designed for completion of automatic machines for welding under flux layer and in shielding gas environment of steel products.
Rectifier can also be used for air-arc cutting with carbon electrode (complete with ballast rheostats).
Main features of welding rectifier VDU-1202
Falling and rigid external characteristics.
Smooth adjustment of welding current in case of falling external characteristics, voltage - in case of rigid external characteristics.
Thyristors are protected from voltage drops by a resistor-capacitive circuit.
Indication of thermal overload.
Possibility of remote regulation of welding parameters.
