Abstract
An automatic electrode wire lead-in device for an electro-erosion spark machine encases the wire in a soft metal or plastic cover of smaller diameter than the entry to the workpiece. A pusher feed mechanism passes the wire to a cutter. A puller feed device draws the wire through the workpiece and passes it to a milling cutter which shreds the spent wire.
