Abstract:
1. A method for providing a one-sided discharge, comprising: providing a generating arrangement capable of producing a high-frequency electrical signal; providing a circuit comprising at least one inductor and at least one capacitor, where the circuit is connected to the generating arrangement; providing only one consumable electrode electrically connected to the circuit, the one consumable electrode is a wire or a rod, the only one consumable electrode is directly attached and fixed to the circuit, and if a workpiece is present the workpiece does not have to be grounded in any manner; and transmitting the high frequency electrical signal to an end of the one consumable electrode to provide a particulate discharge until the one consumable electrode starts to disintegrate over time into a plurality of particles having sizes in a sub-micron range and the one consumable electrode discharges the plurality of particles when the end of the one consumable electrode experiences the high-frequency electrical signal and disintegrates, the end of the one consumable electrode disintegrates in a free discharge space, the free discharge space is a free space.
