Abstract
An electrical control circuit which provides means of initiating the start of upset of a flash welding machine at an operator selectable value of flashing electrical energy. The energy signal for this circuit is taken from an energy monitor, such as the output of the circuit shown in U.S. Pat. No. 4,084,075. The control circuit, by means of a single adjustment of electrical switch means, may include a few additional electrical components to enable initiation of the start of upset, or termination of upset, as a function of platen position rather than as a function of flashing energy. Further, by simple adjustment of additional electrical switch means, further electrical components may be included to control the distance the movable platen moves during the upset portion of the welding cycle. Also, a meter may be included in the circuit to display either upset distance or upset initiation.
