[0002] The function of cutting torch is to mix oxygen and acetylene in proportion, form preheating flame, and spray high-pressure pure oxygen to the workpiece being cut, so that the cut metal burns in the oxygen jet, and the oxygen jet blows away the molten slag generated by combustion to form a cutting gap. It is widely used in various processing industries and is the mainstream cutting tool for metal parts. In actual use, many cutting workers need to hold cutting torches and start work at the same time in some scenarios. During this process, the cutting workers need to frequently turn off or turn on the cutting torch due to operation or process factors. This requires frequent ignition of the cutting torch. In the field, workers holding cutting torches will wear labor gloves or thicker protective gloves, making it difficult for them to operate a lighter for ignition. In addition, cutting torches vary in length, with some exceeding one meter and even reaching two meters in length. The long cutting torch makes it difficult for workers to independently perform ignition, requiring additional personnel to assist with ignition, which further affects production progress.
