Abstract

PURPOSE: To make unnecessary the A/D converter and to exclude unprudent change of welding condition and to avoid the malfunction, by constituting the control unit with the digital processor, up-down counter, maximum value and minimum value setter and comparator or the like.
CONSTITUTION: The welding control unit consists of the digital processor 13 using microcomputer, transmitter 20, up-down counters 21, 25, maximum and minimum setters 22, 24, and comparators 25, 26 or the like. The switch 23 is applied, the pulse train of a given cycle is caused to the oscillator 20, this is counted with the counters 21, 25 and input to the processor 13. In this case, the pulse train is limited with the maximum value setter 22 and the minumum value setter 24, is compared respectively with the comparators 23 and 26 and fed back to the processor 13, and the optimum welding conditions are set. After that, the welding starting switch 18 is applied to perform welding. In this way, the unit is made is expensive, and the counters 21, 25 are not operated even if the instructing means is operated when the power is not supplied. Thus, the welding conditions are not changed unprudently.
