Plasma Jet Cleaning Apparatus And Method
US Patent:
4555612, Nov 26, 1985
Filed:
Oct 17, 1983
Appl. No.:
6/542668
Inventors:
Michael F. Collins - Scotia NY
Francis D. Lordi - Rotterdam Junction NY
Francis D. Lordi - Rotterdam Junction NY
Assignee:
General Electric Co. - Schenectady NY
International Classification:
B23K 900
US Classification:
219121P
Abstract:
Voltage in a transfer arc power supply of a plasma jet cleaning apparatus employed to induce a cathode workpiece current for cleaning a surface of the workpiece includes apparatus for cyclically varying the applied voltage between at least two negative levels which are effective to induce two levels of workpiece current. The more negative voltage is effective to produce a large workpiece current and to clean dielectric impurities from the surface of the workpiece. The less negative voltage is effective to maintain current flow but to permit enhanced motion of the plasma jet over the workpiece surface so that any tendency for sticking of cathode spots on the workpiece during existence of the more negative voltage is counteracted.
