In order to carry out quick and easy changeover of platens (2,3) of an electrode unit (10), a shank holder (12) connects a fixed lower electrode (15) with a platen (2). Further, a movable upper electrode (17) is connected with another platen (3) by a shank (16), 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 desired electrode units to be mounted on, or removed from, a resistance welder (1) 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. <IMAGE> |
