- (1) Re-ignition after safety inspection The firing performance must be checked before using the torch. The method of inspection is to fasten the oxygen hose to the oxygen fitting. After turning on the oxygen, first turn on the acetylene adjustment handwheel, then turn on the oxygen adjustment handwheel, then press the finger on the acetylene joint. If you feel a suction, it indicates that the suction performance is normal. If there is no suction, even if the oxygen flows back from the acetylene joint, it means that the suction performance is not normal and must be repaired, otherwise it is strictly prohibited. If the suction performance is normal, check for leaks. The inspection method is as follows: connect the acetylene hose to the acetylene joint, immerse the torch in a clean water tank, or apply soapy water to each joint of the welding torch, gas valve, etc., then open the adjusting handwheel, and send oxygen and acetylene. Gas, if there is a tight place, you will find bubbles.
- (2) Ignition After the above inspection is passed, the torch can be ignited. Ignition has two methods: first open acetylene and first open oxygen. In order to ensure safety, it is best to first open acetylene, immediately turn on oxygen after ignition and adjust the flame. When the high-power torch is ignited, a friction igniter or other special ignition device should be used.
- 1. Connect the large oxygen bottle (oxygen source) and small oxygen bottle with the original oxygen bridge of this product, and fasten the nut;
- 2. First turn off the low pressure knob of the small oxygen bottle and open the high voltage switch of the small oxygen bottle;
- 3. Slowly open the switch of the large oxygen cylinder. When the air is blown, there is a slight sound of the wire. When the sound disappears, it indicates that the pressure of the two bottles is balanced and the oxygen is completed.
- 4. Turn off the switch of the large oxygen cylinder and the small oxygen cylinder, and lower the oxygen bridge; Note: The oxygen source pressure should not be higher than the working pressure of the small oxygen bottle; the temperature of the small oxygen bottle will increase slightly when oxygen is taken, which is a normal physical phenomenon! Five, gas bottle gas: Butane gas flushing method: After shaking the butane gas cylinder, insert the special gas-filling interface of butane gas vertically, and the pointer shows that the butane gas cylinder can be directly dialed after the flushing; Note: The gas bottle is used for the first time. Because there is air in the bottle, after the gas is flushed, the gas bottle is placed upright, the switch is opened to release the internal air, and the gas is flushed in!
- 1. The operator must hold the welder operation certificate issued by the national labor department, and the undocumented operation produces adverse consequences, and is responsible for it!
- 2. The oxygen cylinder is inspected once every three years, and the gas cylinder is inspected once a year, and the full-time inspection unit at the location of the user is responsible for inspection;
- 3, gas bottles, oxygen bottles should be kept away from fire sources, avoid high temperature sunshine, the surrounding temperature should not exceed 50 degrees Celsius; it is strictly prohibited to use hard objects, heavy objects to knock, hit oxygen cylinders and gas bottles, avoid heat storage, be careful!
- 4. The gas cylinder inflation amount shall not exceed 1/2 of the gas cylinder volume;
- 5. The oxygen in the oxygen cylinder cannot be completely used up. The residual pressure of 0.5Mpa must be retained!
- 6. The failure of the oxygen meter must be repaired and replaced by a professional, and others must not disassemble it!
- 7. Gas bottles and oxygen cylinders must not be mixed with other gases. Do not contaminate oil!
- 8, welding torch, dry fire fire extinguisher and other related main parts, must carefully check the function and performance before each use. 9. If you violate the above matters, you will be conceited at your own risk!
- The oxygen source pressure should not be higher than the working pressure of the small oxygen bottle; the temperature of the small oxygen bottle will increase slightly when oxygen is taken, which is a normal physical phenomenon!
