The article deals with the problem of providing stability of the electrode arc melting process with respect to welding or surfacing technology. It was proposed to use a current source assembled from serially manufactured components. The peculiarity of the proposed source is that it is a source of pulsating DC voltage, powered from 220V single-phase mains. It was shown that the process was equally stable both in case of mechanised welding in carbon gas, as well as during manual welding using electrodes for direct current under the conditions, which are substantially lower than those recommended by the developers of electrode materials. The proposed circuit diagram of the power source provides the ability to vary the value of the current over a wide range, which will extend the technological capabilities of welding, including larger gaps between the edges and in different spatial positions. 15 Ref., 1 Table, 5 Figures.
Keywords: self-regulation, electrode melting process, electric parameters, oscillatory character of the arc, drop overflow, complex current source, volt-ampere characteristic, oscillogram, histogram, breaking arc length
