Abstract
A weld gun cylinder and piston assembly includes a common center end wall interposed between two cylinders. The common center end wall functions as a manifold with bores extending therethrough. The manifold houses two spool valves. The spool valves control the passage of pneumatic pressure through passages of the manifold to and from the cylinders to extend and retract two piston rods for controlling jaws and a weld tip on a robotic arm.
