Abstract
PURPOSE: To supply optimum welding current and enable the carrying out of always accurate and stable welding by judging whether the welding works are properly held or not by supplying weak current before resistance welding thereby supplying optimum welding current by sending the current supply command to the welding power source.
CONSTITUTION: Prior to welding work, the optimum welding conditions obtained by experiment are set in an AC welding power source 20. The welding works 1, 1' are sandwiched and pressed by electrodes 2, 2' and switches S1, S2 are closed by a sampling signal generator 11 to supply the sampling signal to the welding electrodes 2, 2'. The electric quantity generated is input to a comparator 13 and is compared with the electric quantity in a normal welding state before the current supply. If the electric quantity is abnormal, the subsequent current supply is stopped by a stop signal generator 14. In case it is normal, the output signal of the comparator 13 is put in the clock circuit 23 of the AC welding power source 20 to command the start of supplying welding current.
