Welding rectifier of VD-313 U3 type is designed for manual arc welding with covered electrodes of steel products on direct current. Welding current is smoothly regulated by mechanical movement of the magnetic shunt of horizontal execution.
The arc current graduation is made on the outer surface of the shunt. The original mechanism of shunt regulation drastically reduces the time required to change the welding mode.
The rectifier is characterised by simplicity, reliability of construction, low weight, mobility and by welding properties is not inferior to the well-known rectifier VD-306. It is produced in use with and without devices.
