When propane gas cutting low carbon steel plate, the cost varies with the thickness of the steel plate.
用于低碳钢板气割时，气割成本随板厚不同而变化。
The work took cutting machine use raw materials for inflammable gas e. g. acetylene, propane, gas, such as liquefied petroleum gas (LPG).
切割机使用的工作原料为易燃性气体如乙炔、丙烷、液化气等气体。
Thus, the utility model has multiple functions, and the utility model can not only use oxygen and propane gas, but also use oxygen and gasoline to carry out gas cutting.
所以，功能多，既可用氧气和丙烷气，又可用氧气和汽油进行气割。
