This invention relates to controlling a tool for driving fastening elements through firing a fuel. A valve, upon each shot, opens via a current (IA) in a component created by a voltage injection control (Uv). Upon the first one of a series of shots and after the control, the time to is detected of a drop of current in a measuring member upon the transient rise of current and, the opening period To of the valve being predetermined, the end of the injection control is triggered at the time td, after a period To, following the time to, reduced with a period To, of a first rise of the voltage injection control following the beginning of the drop of current or a rise, following the beginning of its drop, of the current. |
