Abstract:
A two-wire metal vapor vacuum arc (MeVVA) vacuum head includes an upper housing and a lower vacuum housing. The lower vacuum housing includes a plurality of ports, a vacuum space, and a first grid positioned in the vacuum space. A plurality of electrodes are positioned in the ports with a first end with an electrical contact area extending into the upper housing, and a second end extending into the vacuum space with an exposed electrical discharge area spaced from the first grid. An electrode of opposite polarity is positioned in one of the lower housing ports with a first end extending into the upper housing and a second end attached to the first grid. An extractor grid is positioned adjacent to the first grid, an electrode selector is operatively connected to the plurality of electrodes, and a trigger generator circuit is connected to an input of the electrode selector.
