Abstract

Machine de soudage et de découpe par arc à plasma com prenant un corps, une électrode, une chambre à gaz inerte, une chambre à eau de refroidissement, ainsi qu'une buse compre nant une ouverture dans laquelle passe l'électrode. L'électrode peut être déplacée dans un sens et dans l'autre à l'intérieur du corps de manière à se déplacer axialement à l'intérieur de l'ouverture de la buse. Applications au soudage par arc à plasma.A plasma arc welding and cutting machine comprising a body, an electrode, an inert gas chamber, a cooling water chamber, and a nozzle comprising an opening through which the electrode passes. The electrode can be moved back and forth inside the body so as to move axially inside the nozzle opening. Plasma arc welding applications.
