Abstract
612,886. Control systems for welding arcs. FOSTER TRANSFORMERS & SWITCHGEAR, Ltd., BAGNALL, R. I., and JENNINGS, R. E. June 5, 1946, No. 17041. [Class 38 (iv)] To ensure a safe no-load voltage on an A.C. arc welding electrode a normally closed switch 2, 3 is held open by a coil 4 connected through rectifiers and a resistance 11 across the welding terminals. In this condition contacts 3, 9 connect the electrode 1 to a low voltage point on the potentiometer 11, 4. When the electrode contacts the work 7, the coil 4 is short-circuited and the connection 2, 3 established, the voltage drop in the impedance 5 preventing sufficient energization of the coil 4 to open those contacts so long as the arc is operative. When the arc breaks, the voltage on the electrode is limited by the action of the coil 4. Time delay may be associated with the opening and also with the closing of the contacts 2, 3.
