METHOD OF ELECTRODE WIRE PRODUCTION Russian patent published in 2015 - IPC B23H1/04 

FIELD: electricity.

SUBSTANCE: initially at one end of wire its diameter is decreased by value of allowance for draw die installation and to length required for the draw die installation, this wire end is fixed in movable pole, then draw die is installed on the wire end, its diameter is equal to the diameter of wire with reduced diameter, this end is secured in movable pole. The opposite end of the weakly tensioned wire is fixed in the fixed pole, then tension forced are applied to wire ends, the force does not exceed the tensile strength of the wire material, beginning of the wire elongation during LV direct current passage through the wire is registered. Then wire end in the fixed pole is released, and wire is drawn through the draw die maintaining permanent tension forces acting on wire.

EFFECT: keeping of straightness and rigidity of long electrodes-tools out of plastic metals, ensuring the required diameter and accuracy of perforated hole.
