Abstract

803,534. Control systems for welding arcs. FOSTER TRANSFORMERS, Ltd., and JENNINGS, R. E. May 10, 1957 [May 18, 1956], No. 15518/56. Addition to 769,433. Class 38 (4). A safety-device for an alternating current arc welding system as described and claimed in the parent Specification is modified in that the relay actuating the normally open and normally closed contacts 7, 8, respectively, is a secondary relay 52 which relay is under the control of a primary relay 5 energized when the welding electrode E is brought into contact with the workpiece W.
