In a travelling wire EDM apparatus, the electrode tool in the form of a wire used for cutting an electrode workpiece is passed through a first zone in which the wire is straightened, preferably by exerting a pull on the wire while the wire is heated. The wire is subsequently cut-off at the bottom of the first zone, and the straightened portion of the wire is then threaded by a carriage through a hole pre-drilled in the workpiece, or through a cut in the workpiece in the event that the wire ruptures during machining, until the end of the wire is engaged in the wire conveyor mechanism.
