[8] Welding torch operation
1. Use copper wire or bamboo sticks for the permeable welding nozzle, and iron wire is prohibited.
2. Check the suction ability of the welding torch or cutting torch before use. The method is: first connect the oxygen pipe, open the acetylene valve and the oxygen valve (at this time the acetylene tube should be disconnected from the welding torch and cutting torch), and gently contact the acetylene air inlet on the welding torch with your fingers. If there is suction force, it means that the suction ability is good. When plugging in the acetylene gas pipe, check the acetylene gas flow to be normal before connecting it. If there is no suction force, even oxygen flows backwards from the acetylene joint, it must be repaired, otherwise it is strictly forbidden to use it.
3. According to the thickness of the workpiece, select appropriate welding torches, cutting torches, welding nozzles, and cutting nozzles to avoid using welding torches to cut thick metals, and use a small cutting nozzle to cut thick metals.
4. After the welding and torch suction inspection is normal, the joints must be connected firmly with the oxygen rubber tube. The acetylene air inlet joint and the acetylene rubber tube should not be too tightly connected, so it is better not to leak and be easily plugged in. Do not use skin tubes that are burned during aging and backfire.
5. The work location should have sufficient clean water for cooling the welding nozzle. When the welding torch (or cutting torch) makes a "crackling" sound due to strong heating, the acetylene gas supply valve must be closed immediately and the welding torch (or cutting torch) must be placed in water for cooling. Be careful not to close the oxygen valve.
6. During short rest, the valve of the welding torch (or cutting torch) must be closed tightly and the welding torch is not allowed to be placed on the ground.

7. ignition operation procedures:
(1) Before ignition, quickly open the welding torch (or cutting torch) valve and blow air with oxygen to check the outlet of the nozzle, but do not aim it at the face to test the air. Do not use it when there is no wind;
(2) When welding into the container, both ignition and extinguishing should be carried out outside the container;
(3) For a sucking welding torch (or cutting torch), the acetylene valve on the welding torch (or cutting torch) should be slightly opened when ignition, and then sent to the wick or match to ignite. When black smoke is found, the oxygen handwheel should be turned on immediately to adjust the flame.If the welding torch is found to be abnormal, once the tempering occurs after ignition and oxygen starts, the oxygen must be turned off immediately to prevent the reignition and explosion or explosion during ignition;
(4) When using an acetylene cutting machine, acetylene gas should be first released, and then oxygen should be released to cause fire;
(5) When using a hydrogen cutting machine, hydrogen should be released first, and then oxygen should be released to cause fire.
8. When extinguishing the flame, the welding torch should first close the acetylene valve and then the oxygen valve. The torch should first be used to cut oxygen, then the acetylene and preheated oxygen valves should be closed. When a fire occurs, if a fire spits on the hose or fire prevention device, the oxygen valve and acetylene valve on the welding torch should be quickly closed, then the first-level oxygen valve and acetylene valve should be closed, and then the fire extinguishing measures should be taken.
9. When using oxygen and hydrogen together, first release acetylene gas, then release hydrogen, and finally release oxygen, and then ignite. When extinguished, turn off oxygen first, then hydrogen, and finally acetylene.
10. When operating welding torches and cutting torches, do not operate the rubber hose on the back. It is prohibited to use the flame of a welding torch (or cutting torch) for lighting.
11. During use, if there is air leakage in the gas passage or valve, the operation should be stopped immediately. Only after the leak is eliminated can you continue to use.
12. When the gas source pipeline passes through the pedestrian passage, a cover should be added and attention should be paid to maintain a safe distance from the electrical circuit.
13. The gas welding (cutting) site must be well ventilated, and mechanical ventilation should be used when welding (cutting) the container.
Automatic (semi-automatic) welding safety operating procedures
