Abstract
In order to carry out quick and easy changeover of platens of an electrode unit, a shank holder connects a fixed lower electrode with a platen. Further, a movable upper electrode is connected with another platen by the shank, which is held by the shank holder. The shank holder and the shank are integrally connected with each other, and are positioned in such a manner that the electrodes can perform resistance welding. Merely detaching the shank and shank holder from their respective platens allows the desired electrode units to be mounted on, or removed from, a resistance welder without making any position adjustments of the electrodes. Consequently, adjustment of the positions of the electrodes becomes unnecessary, thereby facilitating quicker and easier changeover of electrodes.
