The VDU-1602U2 rectifier is used as the power supply at vozdushno arc a molding witness mark on currents 1200-1600A (it is operated in obrubny shops liteynog productions in the conditions of the increased dust content, at the continuous three-shift mode), and also for welding of various metals and alloys in the environment of protective gases and under gumboil, an open arch and a powder wire, electroslag welding and a naplavka currents to 1600 A. Stabilization of output tension and regulation of an inclination of external characteristics is provided in it. At installation of the tough external characteristic the rectifier can be used for welding multion point duty. Use of power silicon uncontrollable gates provides high values of power factors and useful effect, and also high reliability of a source. Smooth regulation of tension without distortion of its form is carried out by magnetic switching of rounds of a secondary winding of the power transformer, cooling - compulsory, air. The rectifier provides good formation of welded seams, reliable excitement of an arch and the minimum spraying of metal that allows to increase labor productivity of the welder, to improve quality of welded connections, especially on sites with considerable fluctuations of a power line. Installation of the rectifier does not require the special base.
