1. The operator must be trained to be familiar with the structural principle and working principle of the straight flame cutting. Familiar with the operation procedures and equipment performance, can operate on the machine.
2. When operators start cutting, they must first check whether all parts can work properly, whether the power supply voltage meets the requirements, and whether the gas pipeline leaks. Check all connecting lines, oxygen gauges, acetylene gauges, pressure regulators, and power sources to ensure that they work without errors. If any abnormality is found, it should be stopped, checked, and repaired immediately. The equipment must not be "sick".
3. The operator must shut off all power and gas lines when he is off work, and vent the remaining gas in the body ducts to extend the service life of the pipes.
4. When the cutting machine is working, the oxygen pressure must not exceed 1 MPa, and the acetylene pressure must not exceed 0.1 MPa.
5. When working, always pay attention to the cutting flame and punching sparks to prevent the gas pipe and wire from splashing.
6. Hyperbaric oxygen must not come into contact with flammable materials such as grease to prevent spontaneous combustion of the grease.
7. The straight bar cutting machine must be operated by dedicated personnel, dedicated maintenance, and prevent erroneous operation; the oxygen and acetylene meters used by the equipment must be calibrated once a year to ensure safe production. All trachea should be replaced once a year under normal conditions of use. If the conditions are harsh, the replacement cycle needs to be appropriately reduced.
8. Straight flame cutting machine operation box must always be kept clean inside and outside, to prevent metal dust, acidic substances and other pollutants, in order to reduce the occurrence of obstacles.
9. The guide rails, racks, and gears of the straight flame cutting machine must be regularly maintained and lubricated to keep the surface tidy, reduce unnecessary wear, extend the service life of components, and improve the quality of workpieces.
10. Operators must regularly check the vertical and horizontal limit switches to ensure that they are in good condition and prevent accidents.
11. Operators must strictly comply with GB9448-1999 national standards for safe operations.
