The utility model relates to a gas path system of a laser cutting machine, which belongs to the technical field of material cutting and comprises a compressed air path, an oxygen path and a nitrogen path, the tail end of the compressed air path is connected with a laser head pipeline, and the tail end of the compressed air path is connected with a second three-way connector. The tail end of the oxygen gas path is connected with the tail end of the nitrogen gas path through a third three-way connector, the last port of the third three-way connector is connected with a second three-way connector at the tail end of the second compressed air branch, and the last port of the second three-way connector is connected with a laser head pipeline. The gas path system is easy to install, stable in performance and high in response speed, can be connected into a plurality of high-pressure gas paths and low-pressure gas paths at the same time, facilitates free switching of different gases according to materials and thicknes
