COMBINED RESONANCE ARC THE DEVICE "RDK-300M"

     The device "RDK-300М" is professional welding device, capable to work at duration of operation і60% practically with any type of electrodes. It is achieved, due to double reservation of capacitor reactor, and also application of the combined resonance scheme..

         High technological properties of resonance welding sources are determined in general selective properties of resonant secondary contour. Application of a resonance contour in a secondary circuits provides practically sine wave form of a curve of welding current, that results in essential advantages of the welding equipment of given class and significant decrease of energy consumption (in 2 - 4 times in comparison with traditional welding transformers).

         The thermal protection of capacitive reactor, executed on a basis the bimetallic relay, is stipulated in the device. A modular design "RDK-300М" allows to use it for supply of two and three-phase arcs, that essentially expands technological opportunities of this equipment. At the request of the customer the rectifier block equipped with the module of the stabilizer of a welding arc burning can be established in the device.
