Gas cutting guns are the main tools for gas cutting, and are mainly composed of acetylene hose nozzles, oxygen hose nozzles, oxygen supply pipelines, acetylene supply pipelines, handles, mixed gas pipes, cutting oxygen pipes and cutting nozzles. The gas inlet velocity and flow rate of traditional gas cutting guns mainly rely on the experience of operators, and digital control of gas cutting gas velocity and flow rate cannot be achieved. Especially in some harsh working conditions, the test process parameters cannot be quickly transferred from the laboratory to the production site in time, which prolongs the process planning time, causes material and gas waste, and increases the overall production cost.
