Abstract
A multi-gas mixer for supplying a gas mixture that can uniformly mix a plurality of gases according to the proportional percentages determined by the mass flow rate of each gas is disclosed. The multi-gas mixer comprises a mixer chamber, a plurality of gas inlets, a gas mixture outlet, and at least one gas rotating and mixing unit. The present invention also provides a method for controlling the percentage of each gas to be mixed by use of a plurality of mass flow rate controllers to control the gas flow to produce a gas mixture according to a predetermined proportionality. When the multi-gas mixer delivers a gas mixture to a high-speed plasma torch, the torch can be stably operated under a high voltage (>85V) and a medium current (<650 A) so that a long-arc, high-temperature and high-speed plasma flame can be generated.
