The condition control system (301) comprises a condition regulator (303), an input device (100) for user based determination of set of values of predefined weighting variables, and a data processor (302) for minimizing a control error. The data processor is implemented in such a way that the minimizing is carried out based on the determined set of values of the predefined weighting variables. The data processor is implemented in such a way that the condition regulator is provided for reaching a desired value of the control variables by minimizing the control coefficient of the control loop. The minimizing is an analytical minimizing of quadratic control deviations. The control variable is a clamp force of a welding tong. The condition regulator is implemented to control the regulation of the clamp force by two pressure variables of cylinder chambers of welding tong symmetrically over respective pressure regulating valve of the pressure chamber. The control loop of the welding tong is described through the two pressure variables of the cylinder chambers of the welding tong, mathematical temporal derivations of both pressure variables, an actual value of the clamp force and corresponding coefficients. The determination of the values is selected from graphical determination by digital slide control, and numerical determination. The data processor is implemented in such a way that a graphical stimulation of an actual curve progress of the control variables is carried out based on the determined set of values. The stimulation is set by a user for improved final determination of the values. Independent claims are included for: (1) a method for regulating control variables of pneumatic welding tongs; (2) a computer-readable medium, on which a computer program element is arranged; and (3) and a computer program element.
