焊接设备在经过一段时间的使用后，总会因为种种原因出现故障。此时，用户必须参照焊接设备使用说明书对照检查与维修，即根据故障现象查找判断原因。下面就来讲讲维修要点。

After a period of use, welding equipment will always fail for various reasons. At this time, the user must refer to the operation manual of the welding equipment for inspection and maintenance, that is, find and judge the cause according to the fault phenomenon. Here are the key points of maintenance.

对于有故障的焊接设备，在不明真相的情况下，不要急于动手，应该先了解设备的性能，询问操作人员产生故障的前后经过及故障现象。对于生疏、复杂的焊接设备，还应先熟悉设备的电路原理和结构特点，遵守相应的规定。

For faulty welding equipment, don't rush to start without knowing the truth. You should first understand the performance of the equipment and ask the operator about the process and phenomenon of the failure. For unfamiliar and complex welding equipment, you should also be familiar with the circuit principle and structural characteristics of the equipment and abide by the corresponding regulations.

拆卸前要充分熟悉每个部件的功能、位置、连接方式以及与周围其他器件的关系。在没有焊接设备线路图和组装图的情况下，应该一边拆卸，一边画草图，一边进行标记，并对拆卸的实物作好标识，注意。

Before disassembly, be fully familiar with the function, position, connection mode of each component and the relationship with other surrounding devices. In the absence of welding equipment circuit diagram and assembly drawing, it is necessary to draw a sketch while disassembling and mark the disassembled objects, and pay attention to safety.

一般应先检查焊接设备外部有无明显受伤的痕迹、电焊机部件有否缺损，并了解其维修史、使用年限、观察使用场所环境和焊接工艺等，然后再对电焊机进行检查。

Generally, it is necessary to check whether there are obvious signs of injury on the outside of the welding equipment, whether the parts of the electric welding machine are damaged, understand its maintenance history, service life, observe the environment of the place of use and the welding process, and then check the electric welding machine.

拆前应排除周边的故障因素，如接线、接地、配电容量以及使用的焊接工艺是否正确，只有在确定是电焊机内部故障后才能拆卸，否则，盲目拆卸可能将焊接设备越修越坏，如焊条电弧焊、埋弧焊、钨极气体保护电弧焊、等离子弧焊及熔化极气体保护焊机等。

Before disassembly, eliminate the surrounding fault factors, such as whether the wiring, grounding, power distribution capacity and the welding process used are correct. Only after it is determined that it is the internal fault of the electric welding machine, can it be disassembled. Otherwise, blind disassembly may make the welding equipment worse and worse, such as electrode arc welding, submerged arc welding, tungsten gas shielded arc welding, plasma arc welding and consumable electrode gas shielded welding machine.

检查焊接设备的机械部件和零件、润滑、气路、水路、油路系统是否存在问题，只有在确定这些系统无故障后，再进行电气方面的检查。

Check whether there are problems in the mechanical components and parts, lubrication, air circuit, water circuit and oil circuit systems of the welding equipment. Only after confirming that these systems are free of faults, can the electrical inspection be carried out.

山东数控焊接设备厂家认为您在检查电路故障时，应利用检测仪器仪表寻找故障部位，确认无接触不良故障后，再有针对性地查看线路与机械的运作关系，以免误判，如点焊、缝焊、凸焊及对焊等设备。

Shandong CNC welding equipment manufacturer believes that when you check the circuit fault, you should use the detection instruments to find the fault position, and then check the operation relationship between the line and the machine after confirming that there is no poor contact fault, so as to avoid misjudgment, such as spot welding, seam welding, projection welding, butt welding and other equipment.

当确定故障部位后再进行检修和更换，解决产生的故障，使焊接设备尽快投入使用，减少因设备故障而造成的经济损失。更多相关内容就来我们网站http://www.tayfsk.com进行咨询吧。

When the fault location is determined, it can be repaired and replaced to solve the fault, so that the welding equipment can be put into use as soon as possible and reduce the economic losses caused by the equipment fault. Come to our website for more relevant content http://www.tayfsk.com Consult.
