力することを特徴とする抵抗溶接制御装置。 A resistor that controls the conduction angle of a silicon-controlled rectifying element connected between a welding power source and a welding transformer to flow welding current to a workpiece that is pressed between a pair of electrode rods facing each other. In a welding machine, a welding current detection means for detecting a welding current, a welding condition setting means for setting welding conditions, and a current value detected by the welding current detection means and set by the welding condition setting means and a current control means for controlling the welding current to a set current value by comparing the current value with the set current value. A test current is applied to the secondary side of the welding transformer to detect that a . A resistance welding control device, wherein a resistance welding control device outputs a secondary cable disconnection prediction signal of the welding transformer when the test current value becomes equal to or less than the reference current value a plurality of consecutive times set in advance.
