Abstract

217,670. British Insulated & Helsby Cables, Ltd., Bullock, S. C., and Wilson, L. B. March 26, 1923. Transformers.-The current supplied to the roller electrodes 7 of a welding machine by the secondary 6 of a transformer 4 is synchronously reduced below welding strength whilst the electrodes are rotated by means of a choking coil 11 in the circuit of the primary 5. The electrodes are rotated through the medium of a pawl lever 15. rachet wheel 16, and belt 17, the lever being connected by links 14, 13, 12<a> to the core 12 so that the latter is pushed further into the core when the electrodes are rotated.
