摘要：The invention relates to a method of monitoring the wear of at least one of theelectrodes (1, 2) of a plasma torch comprising two electrodes (1, 2) having the sameprincipal axis, these electrodes (1, 2) being separated by a chamber (3) for receiving aplasma gas, and at least one means for generating a magnetic field (7) placed locally tosaid at least one electrode, the purpose of which is to monitor the wear, in which the arcroot is swept over a portion of the surface of the electrode starting from an initialposition up to the point where said arc root reaches a defined final position on saidportion, the longitudinal progression of said arc root being determined by a functiondependent on at least time, function f(t), which is fixed. According to the invention, atleast the electrical energy consumed by said torch is measured as a function of time fromthe commissioning of said electrode (1, 2), said measurements are recorded in a storageunit and, based on the temporal variation in at least said consumed electrical energy onat least some of said measurements, a variable ξ(t) for adjusting the function f(t)

determined over a time period Ʈ determined by the state of wear of said electrode (1, 2).
