ABSTRACT:
A resistance welding machine comprises clamping force representing value measuring means for measuring a clamping force representing value corresponding to a clamping force applied on workpieces by a pair of electrodes, clamping force representing value discriminating means for discriminating whether the clamping force representing value measured by the clamping force representing value measuring means is fluctuating or stabilized, and current supply means for supplying welding current through the electrode pair just after a stabilization timing when the clamping force representing value discriminating means discriminates that the clamping force representing value is stabilized.
