Abstract
559,152. Control systems for resistance welding. STANDARD TELEPHONES & CABLES, Ltd., ASHFORD, J. L., and BILLINGS, W. A. July 31, 1942, No. 10732. [Class 38 (iv)] Switching control.-Automatic cut-off of welding current on completion of the weld is effected by a relay 6 having contacts in the supply circuit operated in dependence on the drop in voltage across the weld on fusion. The actuating coil is connected across the primary circuit of the welding transformer 4 in series with the secondary winding of a transformer 10 connected across the electrodes 8. The relay is preferably of quick acting mercury contact as described in Specification 559,017, [Group XXXVII]. Specification 408,431, [Group XI], also is referred to.
