Microcontroller regulator of flash butt welding with compensation of disturbances by the mains voltage on welding current is described. In the algorithm of the regulator operation, nonlinear control characteristics are presented in a tabular form. The algorithm for determining the required angle of thyristor opening during oscillations of mains voltage is described. The choice of parameters was substantiated, influencing the creation of the controller using widely used microcontrollers. 9 Ref., 3 Tabl., 2 Fig.
