Abstract

994,973. Rectifying. LINCOLN ELECTRIC CO. Ltd. Oct. 2, 1962 [July 3, 1961], No. 23985/61. Heading H2F. [Also in Division H1] A polyphase transformer rectifier circuit for D.C. arc welding has inductor variable between 0 and 3 millihenries connected between the rectifier and the welding electrodes. The construction of the choke is described (see Division H1).
