Purpose of the development: Rectifiers BC-450 BC-SR and SL with a 650 volt meter rigid feature designed for welding and surfacing works in the most severe operating conditions (quarries, mines, pipeline routes) is insensitive to the harsh climatic conditions (high and low temperatures, excessive moisture or dust .)

Recommended application field: Rectifiers can be applied for the air carbon arc gouging electrode. A large supply of power allows for the length of the weld communication between the source and power supply for more than 50 meters, which makes it indispensable in carrying out construction works.

The development stage readiness: Introduced in production

Description of the development:
()
Rectifiers provide food for one post or MIG surfacing at currents up to 450A (BC-450SR) and up to 650A (BC-650SR). When MIG welding voltage is adjustable in steps (27 steps). In the power system in addition to the main arc is built parametric choke, which can significantly improve the quality of the welded joints, due to the stabilization provided by the ballast of the welding process and the regulation of short-circuit current that occurs when passing a drop of molten metal from the electrode to the weld pool. In addition to the main power windings, as a rule, use the auxiliary winding, which serves to regulate the value of inductance and, thus, the peak short-circuit current in this transition process. Auxiliary winding to reduce the time short-circuit and reduce the size of the droplets of molten metal, which enhances the formation of the weld and provides a smooth its surface.
