The article shows the results of work to improve the single-phase rectifier for manual arc welding of thin-sheet structures. An additional unit is proposed, which is an electronic switch that includes a control circuit for the rectifier thyristors for two half-periods with a constant frequency, a multiple of the number of half-periods of the rectified current. At the same time, the selection of mode parameters for manual arc welding with a coated electrode allows for a stable quasistationary process of melting and transfer of the electrode metal. The use of an additional unit provides welding thin-sheet structures without reducing the diameter of the coated electrode, by analogy with the known processes for welding in protective gas.
