Abstract

The electrode is held in an arbor forming an axial extension of a massive upper piece part which can be moved laterally relative to the central bore of the body by using a number of symmetricaly placed adjuster screws passing through the sides of the body and bearing on the supporting piece part thus enabling the top of the non consumable electrode to be accurately central relative to the annular plasma nozzle. Reliable method of ensuring uniform plasma and preventing deformation without need to dismantle. Risk of damage to O ring seal is prevented.
