The rectifier welding VDU-506 b/a

Universal welding rectifier VDU-506 is designed for manual arc welding with covered electrodes with direct current, packaging, semi-automatic and automatic machines for welding of steels in shielding gases at a constant current. Is adjustable thyristor rectifier with hard or falling. Difference from version VDU-506С is a classic build and the lack of combined current-voltage characteristics in the mode of semiautomatic welding. Works in complete with semiautomatic machine, PDGO-510-5, with the stabilization of the feeding speed of the welding wire and the possibility of removing the feeder from the rectifier to a distance up to 30 meters, optimal for the craft of welding conditions on arc currents up to 450A (duty cycle=100%). The rectifier has the following main technical solutions: • Stepless regulation of welding current in MMA mode and the welding voltage in the mode МIG/MAG • Special combined external volt-ampere characteristic • Ability to preset the arc voltage in MiG • The sockets 36 to the power of the gas heater • Protection from thermal overload • Quick, safe current connectors • Insulation class H • Forced cooling.
