Depending on the type, a plurality of lower electrodes or pairs of upper and lower electrodes are provided, and these can be switched, so two
Even when welding more than one type of fastening member, two or more welding machines are used as in the past, and after welding the first fastening member, the workpiece is transferred to the second fastening member welding machine. According to the present invention, welding can be carried out in a short time with one welding machine and without moving the location, without requiring the trouble of repairing the Cera+-L.
