摘要：Method of controlling the wear of at least one of the electrodes of a plasmatorch including two electrodes having the same main axis, and being separated by a

chamber designed to receive a plasma-generating gas, and at least one element forgenerating a magnetic field placed locally to the at least one electrode for which thecontrol of wear is sought, in which the arc root is made to sweep longitudinally over aportion of the surface of this electrode from an initial position until the arc root reaches adefined final position of the portion, the longitudinal progression of the arc root beingdefined by a function dependent on at least the time, f(t), which is fixed. At least theelectrical energy consumed by the torch as a function of the time since the electrode wascommissioned is measured, the measurements are recorded in a storage device and, fromthe temporal evolution of at least the electrical energy consumed over at least part ofthe measurements, an adjustment variable ξ(t) is defined for the function f(t) over aperiod of time τ determined by the state of wear of the electrode.
