A method for monitoring a flame cutting process includes a preheating phase, a piercing phase following the preheating phase and a cutting phase following the piercing phase, wherein a cutting torch applies a flame generated by combustion of a gas mixture to an electrically conductive workpiece and wherein an electric current flowing between an electrically conductive part of the cutting torch and the workpiece is measured by a current measuring device during a measuring period. An ignition point at which piercing of a hole through the workpiece using the flame starts due to oxidation of the workpiece is detected by a change in the measured current.
