PROBLEM TO BE SOLVED: To stabilize the coating quality by eliminating affect by a hysteresis phenomenon of a used device like an adjusting valve when controlling a flow rate, and by attaining stable flow rate regulation. SOLUTION: In the paint feed control by an air-operated flow control device discharging a regulated flow, being operated by receiving control air from a control valve via the open/close control valve feeding the compressed air pressure set by remote control for paint feed to a spray gun, the pressure is set lower than a target value, then set to the target value. In changing the set value, the value is once returned to a low value (zero) and then set to the target value. This operation is incorporated in a recording device as a program control.
