1、 Before work

1.檢查所有通風道和閥門是否有漏風現象，氣體裝置是否有效。

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

2.檢查所提供的進口壓力是否符合規范要求。

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

3.檢查所提供的電壓是否符合規范要求。

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

二.工作中

II at work

1 .調整切削鋼板，盡可能與鋼軌平行。

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

2.根據板的厚度和材料選取適當的切割。垂直于鋼板切嘴。

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

3.根據厚度和材料不同，需要重新定義切割機的切削率和預熱時間，以建立預熱氧和合理切削氧壓力。

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.點火后不許接觸火區如果可能，操作員應使用較小的切割方法來保護切割開口。

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.檢查加熱火焰和切斷的氧氣流量，如果發現切割開口損壞，應及時更換和清洗。使用特殊工具清理切割開口。

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.如果切割時出現退燒現象，應及時切斷電源，停止并關閉排氣閥，退燒閥零件應停止并由制造商或人員更換。

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.切割機操作時，數控火焰操作員應始終注意設備的工作狀態。如果發現設備異常，按緊停機開關，及時離開工作崗位。禁止在站點外啟動。

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.操作人員應注意，切割完零件后，重新放置火炬，以便在下一個車間進行切割。

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

9.操作人員根據指定的切割部件選擇切割速度，不能僅僅為了提高工作效率而增加設備的負荷，妥善管理設備壽命與效率和環境保護之間的關系。

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.結論。

III Conclusion.

1.運行結束后，設備應返回位置并關閉排氣閥。管道中的殘馀氣體排出并切斷電源。

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.如果采用軸承系統，應記錄每類設備的運行狀況。

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

3.仔細清理現場，維護工作區的整潔。

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