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

3.根據(jù)厚度和材料不同，需要重新定義切割機的切削率和預(yù)熱時間，以建立預(yù)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(qū)如果可能，操作員應(yīng)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(fā)現(xiàn)切割開口損壞，應(yīng)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(xiàn)退燒現(xiàn)象，應(yīng)及時切斷電源，停止并關(guān)閉排氣閥，退燒閥零件應(yīng)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(shù)控火焰操作員應(yīng)始終注意設(shè)備的工作狀態(tài)。如果發(fā)現(xiàn)設(shè)備異常，按緊停機開關(guān)，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(yīng)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(jù)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(shè)備的負荷，妥善管理設(shè)備壽命與效率和環(huán)境保護之間的關(guān)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(jié)論。

III Conclusion.

1.運行結(jié)束后，設(shè)備應(yīng)返回位置并關(guān)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(tǒng)，應(yīng)記錄每類設(shè)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(xiàn)場，維護工作區(qū)的整潔。

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