Preserved Fulltext
The efficiency values of the wedding arc (the ratio of heat absorbed by the base metal to the electrically supplied arc energy) were measured using 'a certain electrode (B-17 of the Robe Seikosho, the diameter of the core wire is 4mm) under v-arious'conditions : different kinds of current (a. c. and d. c., straight and reverse polarity) different welding currents (100A, 120A and 160A), different arc voltages obtained by main-
