Abstract

The present disclosure concerns a method and an electronic ignition control device of a combustion chamber of a gas-powered fixing tool designed to optimize the quality of the shooting of fixation elements by the tool. According to the principle of the present disclosure, the triggering of the ignition of the chamber to produce the shot is commanded on the condition that the time between the moment when the user places the tool against a work surface and the moment when he pulls on an actuation trigger of the tool is greater than a predefined delay time, to ensure an optimal filling of the combustion chamber with the combustible gas. According to one embodiment of the present disclosure, the triggering of the ignition is enabled on the supplemental condition that a signal of medium ignition voltage is greater than a trigger threshold voltage.
