Title (EN) METHOD AND APPARATUS FOR IMPROVED PLASMA ARC TORCH CUT QUALITY
(FR) PROCEDE ET APPAREIL POUR AMELIORER LA QUALITE DE COUPE D'UN CHALUMEAU A ARC PLASMA
Abstract: front page image
(EN)Controlling the flow of a secondary gas reduces entrainment of the secondary gas and a plasma gas that forms a plasma arc in a plasma arc torch system. Reducing entrainment of the secondary gas and the plasma gas that forms the plasma arc improves the quality of cuts made with the plasma arc torch. This goal is achieved by controlling the density of the secondary gas to reduce a density differential between the secondary gas and the plasma gas.
(FR)Dans la présente invention, le contrôle du flux d'un gaz secondaire réduit l'entraînement du gaz secondaire et du gaz plasma formant un arc plasma dans un système de chalumeau à arc plasma. La réduction de l'entraînement du gaz secondaire et du gaz plasma qui forme l'arc plasma améliore la qualité des coupes réalisées avec le chalumeau à arc plasma.
