交流电焊机的安全操作 | 2013-6-12 9:03:00

1、应注意初、次级线不可接错,输入电压必须符合电焊机的铭牌规定,严禁接触初级线路的带电部分,,次级接线处必须装有防护罩。

2、次级接头连接铜板必须压紧,接线柱应有垫圈,合闸前详细检查接线螺帽、螺栓及其它部件应无松动或损坏。

3、现场使用的电焊机应设有可防雨、防潮、防晒的机棚。并备有消防用品。

4、焊接时,焊接工和配合人员必须采取防止触电、高空坠落、瓦斯中毒和火灾等事故的安全措施。

5、严禁在运行中的压力管、装有易燃易爆的容器和受力构件上进行焊接和切割。

6、焊接铜、铝、锌、锡、铅等有色金属时,必须在通风良好的地方进行,焊接人员应戴防毒面具或呼吸滤清器。

7、在容器内实焊时,必须采取下列措施:容器上必须有进、出风口,并设置通风设备;容器内的照明电压不得超过12,焊接时必须有人在场监护。严禁在已喷涂过油漆或胶料的容器内焊接。

8、焊接预热件时,应设挡板隔离预热件发出的辐射热。

9、高空焊接或切割时,须挂好安全带,焊件周围和下方应采取防火措施并有专人监护。

10、电焊线通过道路时,必须架高或穿入防护管内埋设在地下,如通过轨道时,必须从轨道下穿过。

11、接地线和手把线都不得搭在易燃易爆和带有热源的物品上,接地线不得接在管道、机床设备和建筑物金属构架或铁轨上,绝缘应良好,机壳接地电阻不大于4欧姆。

12、雨天不得露天电焊。在潮湿地带工作时,操作人员应站在铺有绝缘物品的地方,并穿好绝缘靴。

13、长期停用的电焊机,使用时须用摇表检查其绝缘电阻不得低于0.5 兆欧,接地部分不得有腐蚀和受潮现象。

14、焊钳应与手把线连接牢固,不得用胳膊夹持焊钳,清除焊渣时,脸部应避开被清的焊缝。

15、在负荷运行中,焊接人员应经常检查电焊机的升温,如超过A60°、B80°时,必须停止运转并降温。

16施焊现场10米范围内,不得堆放氧气瓶、乙炔发生器、木材等易燃物。

17移动电焊机时应先停机断电,不得用拖拉电缆的方法移动电焊机,如焊接中突然停电,应切断电源。

18作业结束后,清理现场、灭绝火种、清除焊件余热后,切断电源,锁好闸箱,方可离开。
