What matters should be paid attention to when using welding torch and cutting torch safely
Jan 09,2023
Cutting torch and welding torch are gas welders in the important tools, if improper use, may cause flaring, backfire and even combustion and explosion accidents. Therefore, the following matters should be paid attention to during use:
1. According to the welding torch, cutting torch nozzle size, equipped with oxygen and acetylene pressure gas.
2. Do not touch the nozzle and the metal plate.
3. Pay attention to check whether gaskets and valves in each link leak.
4. Nozzle blockage, with a needle poking nozzle, nozzle should be removed, dredged from inside to outside.
5. Before use, the air in the rubber tube should be discharged, and then open the oxygen and acetylene valves respectively. After smooth, ignition and test welding can be carried out.
6. All parts of welding torch and cutting torch shall not be stained with grease.
7. The heat of the nozzle of the welding torch and cutting torch should not be too high. If it is too high, it needs to be cooled with water.
8. ignition, should first open the acetylene valve, lit and then open oxygen. The purpose is to release acetylene - air mixture to facilitate ignition and check for acetylene flow.
9. Acetylene and oxygen valves should be repaired in time if there is air leakage.
10. Do not lay the nozzle of the burning cutting torch or welding torch on the workpiece or the ground.
11. When leaving the working post, it is forbidden to put the lit welding torch and cutting torch on the operating table.
12. Close the valve of oxygen and tempering preventer when changing shift or stopping welding.
13 rubber pipe to special, to mark to distinguish, acetylene pipe and oxygen pipe can not be used in exchange.
14. When it is found that the rubber pipe is frozen, warm water or hot steam should be used to thaw. Fire is forbidden, and oxygen is not allowed to blow the acetylene pipe.
15 oxygen, acetylene rubber tube, do not put, welding torch and cutting torch pipe mouth do not stick to the ground, so as not to fill in earth and impurities, blockage.
