Abstract
PURPOSE: To prevent the cutting by melting, explosive scattering, etc. of welding materials by monitoring the resistance value across welding electrodes and emergently stopping the power supply when the value thereof exceeds a prescribed level.
CONSTITUTION: A current controller 15 is connected to a closed circuit consisting of a pair of electrodes 1 and 2 contacting welding materials 3, and a storage battery 16, and the voltage across the electrodes 1 and 2 is fed back to a voltage comparator 13 for the purpose of comparison with reference voltage. The voltage corresponding to the resistance value across the electrodes 1 and 2 which is determined from the materials and dimensional shapes of weldment and at which the power supply is ought to be stopped and the preset output signal from a power supply stopping reference setter 29 are inputted to a comparator 28. The comparator 28 compares the voltage input proportional to the resistance across the electrodes 1 and 2, and the preset power supply stopping reference voltage, and when the voltage input exceeds the reference voltage, the comparator outputs a signal to a power supply stopping circuit 31 and an alarm gate 32. The input to the circuit 31 outputs a power supply stop signal to a DC amplifier 14, thereby cutting off the output of the amplifier 14 and forcibly stopping the welding current.
