Welding rectifier VD-502-2 BONDS b/y

The rectifier with the throttle current controller VD-502-2, which has a steep current-voltage characteristic designed to supply welding current up to 500 A one position manual arc welding and automatic submerged arc welding. Steeply dipping external characteristics and smooth regulation of the current produced by inductor saturation, included in the secondary circuit between transformer and rectifier unit. The rectifier constructed according to the three-phase bridge circuit using valves B200. The rectifier is adjustable by switching the ranges. Rectifier VD-502-2 is equipped with a voltage regulator, which provides a constant output voltage when the fluctuation of voltage from 5% to 10%, the rectifier cooling air forced.
