Abstract

118,422. Gandolfo, G. March 21, 1917. Heating by electricity.-A welding-machine has an oil-cooled mono-phase transformer a adapted to give a number of different voltages and an oil-cooled variable resistance f in the primary circuit. The secondary current is conveyed bv flexible conductors c to electrode holders c<1>, which are carried by slides m, adjusted by a right and left hand screw and a wheel d. The primary current can be made to pass through the whole or a part of its winding to vary the voltage in the secondary. The conductor b and electrode holders c<1> are cooled by water carried by pipes p, p<1>, o.
