Definition of optimum parameters of devices and modes of their work is one of the major problems of designing. Most the wide circulation was received by methods of mathematical modeling of electric cars. The modern software allows to count precisely enough electromagnetic processes in the transformer and to define operating modes. Computer program MathCAD allows to work directly with mathematical apparatus, to make changes and corrective amendments. Definition of operating modes of the welding transformer described in [6] by means of mathematical modeling and their estimation with results of researches is a research objective. For this purpose it is necessary to define parameters of the welding transformer and, having substituted them in mathematical model, to calculate currents. The mathematical model can be used for definition of optimum parameters of the welding transformer at known currents.
