Abstract

Improvements introduced in the machines for welding by electrical resistance, for the connection to a three-phase network with three adjustable gas discharge pipes for the primary current of the welding transformer and a control connection for said pipes, characterized in that each discharge pipe of gas is bypassed by the serial connection of a disconnectable valve and with opposite polarity to the gas discharge tube and of a resistor, to which a current corresponding to at least the remainder of the welding transformer is applied, switches being provided for of two connection positions, in which the gas discharge pipes with the same polarity are connected in one position to the welding transformer and each to one of the three phases, and the valves are connected instantaneously after all the discharge pipes are turned off, and in the other position of the switch coupled the first and the second gas discharge pipe to the first phase for they are opposite each other, while the third discharge pipe is out of service, the valves being disconnected.
