VD single-operated
rectifiers
VD-306 B is designed for powering the direct current electric
welding arc during manual arc welding, cutting and build-up welding of metals
using a three-phase AC power supply.
Operational functionality: This rectifier
can be used in agricultural works,in servicing depots and for various operations
in construction, repair, sanitary engineering and other works.
VD-306E
is designed for manual arc welding and cutting.
Stepless welding current control
is carried out using movable transformer winding.
This rectifier ensures a
reliable arc initiation, even with small currents and voltages.
