焊接專機使用過程中不允許超載，否則將會因過熱而燒毀焊接專機或造成火災(zāi)；超載造成絕緣損壞，還可能引起漏電而發(fā)生觸電事故。下面來講講山東焊接專機焊接操作時的十個要點。

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，應(yīng)先檢查焊機設(shè)備和工具是否，如焊機接地及各接線點接觸是否良好，焊接電纜絕緣外套有無破損等。

(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）在設(shè)備上進行焊接前，應(yīng)先把設(shè)備的接地或接零線拆掉，焊接完后再恢復(fù)。

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

（3）進行電焊作業(yè)前，應(yīng)檢查作業(yè)環(huán)境，危險有害因素和設(shè)置監(jiān)護人員。當(dāng)附近有其他人員和有關(guān)設(shè)施時，應(yīng)采用屏護和間隔等，保證作業(yè)。需在高處焊接作業(yè)時，須掛好帶。

(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）更換焊條時，焊工應(yīng)戴絕緣手套。

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

（5）在金屬容器內(nèi)、金屬結(jié)構(gòu)上及其他狹小工作場所焊接時，觸電的危險性大，須采取專門的防護措施。如采用墊橡皮墊，戴皮手套，穿絕緣鞋等，以保障焊工身體與焊件間絕緣。禁止使用簡易無絕緣外殼的電焊鉗。

(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）改變焊機接頭，更換焊件需要改接二次回路時，應(yīng)選擇轉(zhuǎn)移工作地點、焊機檢修暫停工作或下班等，且須切斷電源后方可進行操作。

(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）焊機應(yīng)設(shè)置在防雨和通風(fēng)良好的地方。焊接現(xiàn)場不準(zhǔn)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）交流弧焊機一次側(cè)電源線須絕緣良好，不得隨地拖拉，長度應(yīng)不大于5m，進線處須設(shè)置防護罩。

(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）焊機二次接線宜采用YHS型橡皮護套、銅芯多股軟電纜，電纜的長度應(yīng)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）根據(jù)施工需要，焊接專機宜按區(qū)域或標(biāo)高層集中設(shè)置，并應(yīng)編號。

(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專機應(yīng)設(shè)置在干燥場所，并設(shè)棚遮蔽。且焊接專機的電源開關(guān)應(yīng)單獨設(shè)置，直流焊接專機的電源應(yīng)采用啟動器控制。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://m.hongqicables.com咨詢吧！

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.
