ABSTRACT OF THE DISCLOSURE A counterbalance cylinder pressure control for a mechanical press which has a slide, a die punch mounted on the slide and a die shoe. A coded plug is attached to the die shoe and means are provided for reading the code on the plug which indicates the weight of the die punch associated with that die shoe. A voltage signal produced from the decoding of the plug is used in a servo system to control the air pressure in the counterbalance cylinders. When a new die set is placed in the mechanical press, the coded plug attached to the die shoe is read and the servo system operates to reset the counterbalance cylinder pressure to the correct value. -1-
