Installation and method for working on a metal component with a plasma arc with inverse polarity to improve performance with thicker materials

摘要

Working with a plasma arc uses at least one plasma torch equipped with an electrode connected to a source of electric current to generate a plasma jet to work on a metal component. At least temporarily, the electrode is connected to the anode of the source of electric current and the metal component to be worked on is connected, to the cathode of the source of electric current. Independent claims are also included for: Installations using this method for working with a plasma arc, in particular for plasma cutting.
