Arc device with adjustable cathode
An arc plasma generating system includes components for adjusting spacing between the cathode (20) and the anode (18). A piston (96) affixed to the cathode is slidingly positioned in a cylinder partitioning therein a first chamber (108) and a second chamber (110). The first chamber (108) is receptiv...

| description | An arc plasma generating system includes components for adjusting spacing between the cathode (20) and the anode (18). A piston (96) affixed to the cathode is slidingly positioned in a cylinder partitioning therein a first chamber (108) and a second chamber (110). The first chamber (108) is receptive of discharging cooling fluid at reduced pressure. A first valve (162) selectively infuses pressurized control fluid into the second chamber (110) such as to move the piston (96) against the reduced pressure and thereby move the cathode (20) axially in a first direction. A second valve (164) selectively discharges the control fluid from the second chamber (110) such that the reduced pressure in the first chamber (108) moves the piston (96) opposite the first direction. Telescoping tubing (144) affixed between the piston (96) and the end wall (96) of the cylinder (80) is located within the cylinder (80) and conveys cooling fluid to the cathode. A flexible electrical cable (166) connected between the cathode and a source of arc current is located within the cylinder member such as to be cooled by fluid therein. |
