An apparatus and method for automatically controlling the clutch torque of a mechanical press is utilized to lessen the impact of a die wreck condition. Press machine operation is continually monitored including slippage of the engaged clutch relative to the flywheel. The clutch is initially engaged at full engagement pressure. Clutch engagement pressure is then reduced until clutch slippage occurs. At the point at which clutch slippage occurs, clutch engagement pressure is increased until clutch slippage is eliminated. Clutch slippage continues to be monitored and if clutch slippage occurs again, a press fault is indicated. Since the operating tonnage of the mechanical press is kept to a minimum, press damage due to a die wreck is minimized.
