Title:
【発明の名称】電気アーク発生装置
Document Type and Number:
Japanese Patent JP2813398
Kind Code:
B2
Abstract:
An electric arc generating device including, a first electrode (1) and at least two further electrodes (2, 3, 4). A source of electrical power (11) is connectable to said electrodes so as to cause an arc to burn between the first electrode and one of the further electrodes. The distribution of power within the zone of the arc is controlled by repetitively changing the path of the arc. That is, one root of the arc may remain attached to the first electrode, whereas attachment of the other root is transferred between twor or more of the further electrodes on a repetitive basis. The timing and extent of each change may vary according to circumstances of use. The changes in arc path are due at least in part to repetitive modification of the influence of the power source on one or more of the further electrodes, but variation of the flow rate of gas/material (7, 9, 10) through the arc zone (6) can be another controlling factor.
