EB-1 welder an operating rod, which moves up and down through the tubular column, is attached to a lever in the welder frame which in turn transmits vertical movement to a non-rotating outer quill. When the operating rod is pushed upward, the outer quill is moved downward until the upper electrode contacts the work. This upper electrode is attached to a low inertia inner quill operating in oilite bushings. A downward pressure is exerted on this inner quill by a graduated pressure spring which determines the actual welding force.. By means of mechanical linkages maximum welding force with very little muscular effort is obtained. Such linkage action permits rapid approach of the upper electrode to the work, controlled deceleration and contact on the work without impact. The foot operating mechanism consists of a swinging type treadle, adjustable to individual leg length and angle requirements. A bicycle type pedal permits natural leg motion for high-speed production.
