Abstract

PURPOSE: To easily detect the interelectrode voltage depending on a simple constitution, by obtaining a false interelectrode voltage from the secondary circuit of arbitrary welder, and by subtracting the reactance and the voltage drop due to the resistance from the value of this false interelectrode voltage.
CONSTITUTION: The false interelectrode voltage is detected from an arbitrary voltage-detecting-point apart from the welding electrode in the secondary circuit of the welder; then, the reactances X1 and X2 existing across this detecting point and the welding electrode, and the voltage drops R1 and R2 due to the resistance, are subtracted from this false interelectrode voltage, for obtaining the interelectrode voltage between the resistance welding electrodes. Instead of this false interelectrode voltage, the secondary terminal output V1 of the transformer, or the voltage V2 drawn out of the midway of the secondary cable can be employed. Besides, the voltage drop can be obtained by detecting the rate of current change di/dt or the current (i).
