The function of the tig torch body is to mix oxygen and acetylene in proportion to form a preheating flame, and to spray high pressure pure oxygen onto the work piece to be cut, so that the cut metal is burned in the oxygen jet, the oxygen jet and the fusion generated by the combustion. The slag blows away to form a slit. The torch is the primary tool for gas cutting work pieces.

Extinguishing occurs during welding. One of the reasons is that the cutting nozzle is loose. The cutting nozzle should be reconnected with the torch body in time to ensure the tightness. Or because the temperature of the cutting nozzle and the mixed gas pipe is too high, the fuel pipe should be closed and the cutting nozzle should be immersed in water to cool. . There are many factors affecting the injection-type liquid fuel torch, including design parameters, assembly quality and operation methods. In order to achieve the best results of the injection-type torch, it is necessary to combine theory with practice to obtain the best design parameters and operation methods to improve work efficiency and safety of the production process. In the process of cutting with a torch, there are other unexpected problems that need to be designed and treated by the user and summed up in time to achieve the best results.
