焊接专机使用过程中不允许超载，否则将会因过热而烧毁焊接专机或造成火灾；超载造成绝缘损坏，还可能引起漏电而发生触电事故。下面来讲讲山东焊接专机焊接操作时的十个要点。

Overload is not allowed during the use of the special welding machine, otherwise the special welding machine will be burnt or cause fire due to overheating; Overload may cause insulation damage and electric shock due to electric leakage. Now let's talk about the ten key points in the welding operation of Shandong special welding machine.

（1）焊接前，应先检查焊机设备和工具是否，如焊机接地及各接线点接触是否良好，焊接电缆绝缘外套有无破损等。

(1) Before welding, check whether the welding machine equipment and tools are safe, such as whether the grounding of the welding machine and the connection points are in good contact, and whether the insulating jacket of the welding cable is damaged.

（2）在设备上进行焊接前，应先把设备的接地或接零线拆掉，焊接完后再恢复。

(2) Before welding on the equipment, the grounding or neutral line of the equipment shall be removed first and then restored after welding.

（3）进行电焊作业前，应检查作业环境，危险有害因素和设置监护人员。当附近有其他人员和有关设施时，应采用屏护和间隔等，保证作业。需在高处焊接作业时，须挂好带。

(3) Before electric welding operation, the operating environment shall be checked, hazardous and harmful factors shall be removed, and supervisors shall be arranged. When there are other personnel and relevant facilities nearby, screen and safety interval shall be adopted to ensure the safety of operation. When welding at heights is required, safety belts must be hung.

（4）更换焊条时，焊工应戴绝缘手套。

(4) When replacing welding rods, welders shall wear insulating gloves.

（5）在金属容器内、金属结构上及其他狭小工作场所焊接时，触电的危险性大，须采取专门的防护措施。如采用垫橡皮垫，戴皮手套，穿绝缘鞋等，以保障焊工身体与焊件间绝缘。禁止使用简易无绝缘外壳的电焊钳。

(5) When welding in metal containers, metal structures and other narrow workplaces, the risk of electric shock is high, and special protective measures must be taken. For example, rubber pads, leather gloves and insulating shoes are used to ensure the insulation between the welder's body and the weldment. It is prohibited to use simple welding tongs without insulating shell.

（6）改变焊机接头，更换焊件需要改接二次回路时，应选择转移工作地点、焊机检修暂停工作或下班等，且须切断电源后方可进行操作。

(6) When changing the welding machine joint and changing the weldment, it is necessary to change the secondary circuit, select the transfer work site, suspend the work of the welding machine maintenance or go off work, and cut off the power before operation.

（7）焊机应设置在防雨和通风良好的地方。焊接现场不准堆放易燃易爆物品。

(7) The welding machine shall be set in a rain proof and well ventilated place. Inflammables and explosives are not allowed to be stacked on the welding site.

（8）交流弧焊机一次侧电源线须绝缘良好，不得随地拖拉，长度应不大于5m，进线处须设置防护罩。

(8) The power line at the primary side of AC arc welding machine must be well insulated, and shall not be dragged anywhere. The length shall not be more than 5m. The incoming line must be provided with a protective cover.

（9）焊机二次接线宜采用YHS型橡皮护套、铜芯多股软电缆，电缆的长度应不大于30m。

(9) YHS type rubber sheath and copper core multi strand flexible cable should be used for the secondary wiring of the welding machine, and the length of the cable should not be more than 30m.

（10）根据施工需要，焊接专机宜按区域或标高层集中设置，并应编号。

(10) According to the construction needs, the special welding machines should be set up in a centralized manner according to the area or standard high level, and should be numbered.

此外布置在室外的焊接专机应设置在干燥场所，并设棚遮蔽。且焊接专机的电源开关应单独设置，直流焊接专机的电源应采用启动器控制。更多相关内容就来我们网站http://www.tayfsk.com咨询吧！

In addition, the special welding machine arranged outdoors shall be set in a dry place and covered by a shed. The power switch of the special welding machine shall be set separately, and the power supply of the DC welding machine shall be controlled by the starter.
