    摘要： The invention relates to a method for splicing a wire in a wire discharge machine. To provide a splicing method which does not require any auxiliary means as in the prior art, the invention comprises the steps of straightening the wire electrode by applying tension exceeding the limit of elasticity thereof; melting a portion of the strident wire electrode by passing electric current therethrough; separating the wire electrode at the melted portion thereof by applying tension to the wire electrode and inserting either end of the separated wire electrode into a through hole in a workpiece.

    摘要： A method and a device are provided for confirming that a wire electrode for a wire cutting discharge machine, which is fed from the wire delivery side, has penetrated a wire guide section on a wire take-out side, in which a wire electrode (3) enters into a wire delivery section (11) where its speed is detected, then passes into a wire cutting discharge machine and through or by a workpiece (W) and out through a wire guide section (8) and a wire feed-out section (13). The wire delivery speed is then compared in a comparison means (51 ; 61) either to a preset speed or to the wire speed detected in the wire guide section (8), the output of the comparison forming the basis of a decision by a decision means (55 ; 63) as to whether or not the wire electrode has penetrated the wire guide section on the wire take-out side.
