Abstract: A control system for controlling a work machine like a workpiece attitude changing device, by the welding torch of a welding robot. The system includes detecting members for detecting the welding torch at multiple locations in a casing; a plurality of air supply tubes with one end connected to an air source and the other end having an air supply aperture for supplying operating air to the work machine; electromagnetic opening and closing valves located at an intermediate position in each air supply tubes; a control circuit unit inputting detection signals from the detection members and outputting control signals to prescribed electromagnetic opening and closing valves. The detecting members are respectively composed of a plurality of optical sensors capable of detecting the welding torch at two locations; and the control circuit unit outputs a prescribed control signal when detection signals are obtained simultaneously from the respective optical sensors.
