A new type of timer and controller for use in the Field of resistance welding of thin alloy sheets of brass, aluminum, stainless steel, and kindred metals where a very high current is applied for a very short interval of time is described in this paper. In this new timer, the ``ignitron´´ type of tube is applied for obtaining precise control of the welding current. Controls for intermittent duty, high speed automatic duty, and heavy duty seam welding are described.
