摘要
A resistance welding machine includes a first electrode and a second electrode which are configured so that the first and second electrodes can hold a workpiece therebetween and apply a current to the workpiece. The first electrode includes a first inner electrode and a first outer electrode disposed outside the first inner electrode at a predetermined interval. The second electrode includes a second inner electrode and a second outer electrode disposed outside the second inner electrode at a predetermined interval. The resistance welding machine further includes a control unit that can control the pressing state of the workpiece with the first and second electrodes according to predetermined welding conditions and selects a pair of electrodes that apply a current to the workpiece from the first inner electrode, the first outer electrode, the second inner electrode, and the second outer electrode.
