The article substantiates the relevance of research for solving problems of designing automatic control systems for welding processes. The purpose of the experiments was determined to obtain empirical dependencies of welding parameters, which could be used to identify the parameters of the transfer function of the automatic control system. A brief review of similar scientific papers. The description of the shunting mechanism is given, its influence on the efficiency of the welding process is studied. A number of empirical dependences of changes in the parameters of plasma welding on the conditions of use of the filler wire were obtained.

Keywords: plasma welding, filler wire, control system, shunting, plasma gas, experimental dependencies
