Abstract
PURPOSE: To improve the efficiency of operation and also, to enable to control the welding quality stably, by detecting the production of expulsion and surface flash during resistance spot welding and controlling welding current according to the value of current of production limit of expulsion and surface flash.
CONSTITUTION: Detected signal of the sensor 16 is supplied to the comparison circuit 20 passing through the switch 18 and is compared with the standard voltage from the generator 24. Then, the signal is supplied to the monostable multivibrator 26 when the signal of sensor 16 is exceeded the standard voltage shown by detecting characteristics of expulsion and surface flash. Moreover, when the expulsion and surface flash are not produced, welding current is increased one stage by step-up control circuit 28 of the controlling circuit 12 by output signal from the vibrator 26. Also, when the expulsion and surface flash are produced, step-down control is carried out and the control decreasing the welding current one stage, is carried out. Hereby, the welding current is able to control according to the value of current of production limit of expulsion and surface flash and extremely effective welding is able to carry out
