 Abstract. The paper presents a development of control system for an electric arc welding installation based on the analysis of thermal processes and algorithms developed by the authors for controlling the operating modes of the power supply. Mathematical and simulation models of welding processes with control functions of pulsed welding modes are used. The electrothermal factors influencing the process of forming a weld are considered. A method for controlling the current pulses of the welding arc is proposed.
