1、 Before work

1.检查所有通风道和阀门是否有漏风现象，气体装置是否有效。

1. check whether all ventilation ducts and valves have air leakage and whether the gas device is effective.

2.检查所提供的进口压力是否符合规范要求。

2. check whether the inlet pressure provided meets the specification requirements.

3.检查所提供的电压是否符合规范要求。

3. check whether the supplied voltage meets the specification requirements.

二.工作中

II at work

1 .调整切削钢板，尽可能与钢轨平行。

1 . Adjust the cutting steel plate to be parallel to the rail as far as possible.

2.根据板的厚度和材料选取适当的切割。垂直于钢板切嘴。

2. select appropriate cutting according to the thickness and material of the plate. Perpendicular to the steel plate cutting nozzle.

3.根据厚度和材料不同，需要重新定义切割机的切削率和预热时间，以建立预热氧和合理切削氧压力。

3. according to different thickness and materials, it is necessary to redefine the cutting rate and preheating time of the cutting machine to establish preheating oxygen and reasonable cutting oxygen pressure.

4.点火后不许接触火区如果可能，操作员应使用较小的切割方法来保护切割开口。

4. do not touch the fire area after ignition. If possible, the operator should use a smaller cutting method to protect the cutting opening.

5.检查加热火焰和切断的氧气流量，如果发现切割开口损坏，应及时更换和清洗。使用特殊工具清理切割开口。

5. check the heating flame and cut-off oxygen flow. If the cutting opening is damaged, it should be replaced and cleaned in time. Use special tools to clean cutting openings.

6.如果切割时出现退烧现象，应及时切断电源，停止并关闭排气阀，退烧阀零件应停止并由制造商或人员更换。

6. in case of fever relief during cutting, the power supply shall be cut off in time, the exhaust valve shall be stopped and closed, and the parts of the fever relief valve shall be stopped and replaced by the manufacturer or professional personnel.

7.切割机操作时，数控火焰操作员应始终注意设备的工作状态。如果发现设备异常，按紧停机开关，及时离开工作岗位。禁止在站点外启动。

7. during the operation of the cutting machine, the numerical control flame operator shall always pay attention to the working state of the equipment. If the equipment is found abnormal, press the stop switch firmly and leave the post in time. It is forbidden to start outside the site.

8.操作人员应注意，切割完零件后，重新放置火炬，以便在下一个车间进行切割。

8. the operator shall note that after cutting the parts, the torch shall be placed again for cutting in the next workshop.

9.操作人员根据指定的切割部件选择切割速度，不能仅仅为了提高工作效率而增加设备的负荷，妥善管理设备寿命与效率和环境保护之间的关系。

9. the operator shall select the cutting speed according to the specified cutting parts, and shall not increase the load of the equipment just to improve the work efficiency, and properly manage the relationship between the service life of the equipment and the efficiency and environmental protection.

三.结论。

III Conclusion.

1.运行结束后，设备应返回位置并关闭排气阀。管道中的残馀气体排出并切断电源。

1. after the operation, the equipment shall return to the position and close the exhaust valve. Exhaust the residual gas in the pipe and cut off the power supply.

2.如果采用轴承系统，应记录每类设备的运行状况。

2. if a bearing system is used, the operating conditions of each type of equipment shall be recorded.

3.仔细清理现场，维护工作区的整洁。

3. carefully clean the site and maintain the cleanliness of the work area.
