Method and arrangement for supplying a plasma torch with a plasma gas mixture of at least two different gases or mixed gases or at least one gas and at least one mixed gas

摘要

A method for supplying a plasma torch with a plasma gas mixture of at least two different gases or mixed gases or at least one gas and at least one mixed gas in which a volume flow control of the gases and / or mixed gases is performed, DOLLAR A characterized in that the volume flow control in combination with eienr pressure control of the gases and / or mixed gases is carried out, such that by means of the pressure control, the amount of the total volume flow through the plasma torch of the plasma torch is controlled and controlled by means of the volume flow control the total volume flow resulting volume flow components taking into account the desired plasma gas mixture composition.
