PURPOSE:To obtain always an correct output with respect to a set output by correcting successively the reference signal to be supplied to a control part of a welding machine body until the set value of an output setter and the actual output coincide with each other. CONSTITUTION:A control device is constituted with the output setter 1 for determining the output of the welding machine, a storage part 2 wich stores the combination of each output signal thereof and each reference signal for output control to be determined in accordance with the output signal respectively as one set of data, a reference signal retrieval part 3 which is inputted with the output signal from the setter 1 and reads out the corresponding reference signal from the part 2, a means 4 for correcting the reference signal which corrects the output signal from the part 3 until the set value from the setter 1 and the actual output value coincide and an output control part 5 which controls the output of the welding machine by the corrected reference signal. A subtractor 9, a reference setter 10, a comparator 11, a latch circuit 12 and an alarm 13 constitute a discriminating means. |
