Abstract
PURPOSE: To detect the inter-tip voltage easily with a high precision, by operating and processing voltage values between welding electrodes just after power supply start and just before power supply end, the integral value of the AC waveform, and each data of the power supply time.
CONSTITUTION: The inter-tip voltage is input to rectifying circuit II and A/D converter IV with sample hold function through filter circuit 1. The output of rectifying circuit II is made into two digital pulses for one-time power supply through comparing circuit 3 and is input to microcomputer V. Computer V receives this signal to control A/D converter IV and subjects the inter-tip voltage to A/D conversion at every fixed interval and accumulates it. This accumulated data, inter-tip voltage values just after power supply start and just before power supply end, and the value of the time from power supply start to power supply end are used to obtain the integral value of the true inter-tip voltage by the operation processing. By this method, various kinds of monitor and quality control are made high-precision.
