All operational controls - air, water and solid state electronic - are machine mounted, for easy access, safe and simple maintenance. Weld sequence controller, sophisticated Quartz timer with squeeze, weld, hold and off timings with singlerepeat cycle facility, weld timing being controlled by Thyristor circuit, heat controllable from 5% to 95%. Electrode cushion control adjusts the descent of the upper electrode to any desired speed and completely eliminates 'hammer blow'. Sturdy ram assembly permits high speed operation.
