The universal welding rectifier is designed for automatic and semi-automatic gas-shielded and submerged arc welding as well as for manual arc welding by stick electrodes of all types.The power thyristor unit with a ratio of current safety factor of K=1.25 is installed on the rectifier.

Availability of a special rectification circuit with a low pulsation factor provides for high quality of weld, minimum spattering and saving of welding materials.
