摘要：
A control apparatus for a resistance welding machine comprises a welding current detecting device for detecting a welding current, interelectrode voltage detecting device for detecting an interelectrode voltage, a calculating section for predicting a nugget growth or estimating an expulsion & surface-flash generation probability, and control section for controlling the welding current so that the nugget growth or the expulsion & surface-flash generation probability can be adjusted to a predetermined value.
