Abstract

435,031. Transformers. SCIAKY, D., 13, Rue Charles-Fourier, Paris. Feb. 12, 1934, No. 4613. Convention date, Feb. 14, 1933. [Class 38 (ii)] In an electric welding machine 8 having the conductors of the transformer secondary circuit cooled by circulation of a cooling fluid, a safety device 1 operated by the pressure of the cooling fluid is arranged at the outlet of the cooling system and is adapted to cause the opening of the electric circuit of the machine when the pressure of the cooling fluid falls below a predetermined value. The safety device 1 may be in the form of a pressure gauge, having a contact 11 with which the pointer of the gauge engages when the pressure of the cooling fluid is less than the predetermined minimum value. The engagement of the pointer with the contact 11 closes the circuit of a relay 2 and thereby opens contacts 3 which are arranged in a circuit containing the operating coil 6 of the circuitbreaker 9 controlling the machine 8. The relay, when energized, also closes contacts 4 arranged in the circuit of a warning lamp 5.
