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 rectifier connected between a commercial power source and a welding transformer to flow welding current to a workpiece that is pressed between a pair of opposing electrode rods. 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 a current control means for controlling the welding current to a set current value by comparing the current value with the current value set, and a pressure control means for controlling the pressure force of the electrode rod to a desired pressure force, and , the initial pressing force of the electrode rod by the pressing force control means is set to such a pressing force that the tip of the electrode rod makes relatively light contact, and both electrode rods come into contact with the object to be welded with the preset low initial pressing force. Low initial pressure control, in which the welding current is started after switching the pressure of the electrode rods to a predetermined pressure necessary for welding, and a preset high initial pressure that allows both electrode rods to weld the welded object. A high initial pressure control that switches the pressure of the electrode rod to a predetermined pressure necessary for welding after contacting the electrode rod and then starts applying welding current, and a high initial pressure control that starts welding the welding current from the time when the initial pressure is applied to both electrode rods. Pressurization is performed by switching to either one of the predetermined pressure control, which applies a necessary predetermined pressure force and applies the welding current.
1. A resistance welding control device comprising a pressurizing force switching control means for controlling energization.
