Abstract

111,925. Roulland, C. Dec. 22, 1916. Heating by electricity.- In electric welding, the voltage is maintained constant by adjusting the number of active turns in the primary or secondary of a transformer a. An adjustable non-inductive resisttance b is arranged in series with the secondary. The switchboard for the resistance and winding switches and measuring instruments and the resistance grids may be carried on the transformer.
