摘要： According to the invention, the ring transformer for resistance butt welders comprises a plurality of sections, each composed of a non-closed magnetic core, a part of the primary winding and a part of the secondary winding. Each section is so arranged with respect to the other sections that the end faces of its non-closed magnetic core are in contact with the end faces of the two adjacent sections, whereby the non-closed magnetic cores of all the sections make up a closed magnetic core of the transformer. The primary winding of each section is connected to those of all the other sections so that they all make up the primary winding of the transformer. The secondary winding of each section is connected to those of the other sections so that they all make up the secondary winding of the transformer.
