Abstract

PURPOSE:To automatically supply a new electrode when an electrode is disconnected, by interposing a roller mechanism, feeding a wire electrode and comprising a reverse rotation preventive mechanism, and a tension mechanism, controlling tension of the electrode, in the above described feeder. CONSTITUTION:If a wire electrode 38 is disconnected, movement of the electrode 38 is stopped by a reverse rotation preventive mechanism 29, and a signal is output from a rotation detector unt 86 to change the tension of a tension mechanism 80 to a prescribed value, and this causes the electrode 38 to hold its condition as left in a clamped state by a roller mechanism 22. Under this condition, a pipe guide 36 is lifted through a motor 20 to the uppermost part of a guide 14, and an electromagnetic brake 83 and motor 84 are controlled to collect the electrode 38 to a bobbin 82. Then the pipe guide 36 is moved onto the concentrical shaft with a disconnection start machined hole 12a, and an electrode feeder is operated to automatically feed the electrode 38 in such a manner as to be extended through in a work 10.
