Abstract

593,495. Supply systems for welding arcs. ARC MANUFACTURING CO., Ltd., and MOFFATT, R. G. March 19, 1945, No. 6914. [Class 38 (iv)] In an arc welding plant a high-frequency, high-voltage A.C. produced by an oscillator circuit is superimposed upon the welding current by a low-resistance choke coil or autotransformer 1 in series with the source 2 of welding current, any low-frequency, highvoltage A.C. appearing across the choke coil is short-circuited and the operator protected. Specification 13888/41, as open to inspection under Sect. 91, is referred to.
