焊接专机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。下面山东焊接专机厂家来讲讲焊接专机设备故障的维修方式！

After a period of use, the special welding equipment will always fail for various reasons. Next, Shandong welding machine manufacturer will talk about the maintenance method of welding machine equipment failure!

1、先问后动

1. Ask first and move later

对于有故障的焊接专机设备，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、复杂的焊接专机设备，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 the special welding equipment with faults, do not rush to work when the truth is unknown. You should first understand the performance of the equipment and ask the operator about the process and phenomenon of the fault. For unfamiliar and complicated special welding equipment, it is also necessary to be familiar with the circuit principle and structural characteristics of the equipment and observe 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。在没有焊接专机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, location, connection mode of each component and its relationship with other surrounding components. In the absence of the wiring diagram and assembly drawing of the special welding machine, it is necessary to draw a sketch while disassembling, mark at the same time, and mark the disassembled objects for safety.

2、先外后里

2. Outside before inside

一般应先检查焊接专机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, first check whether there are obvious signs of injury on the outside of the special welding equipment, whether there are defects in the parts of the electric welding machine, and understand its maintenance history, service life, observe the environment of the use site and 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专机设备越修越坏，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。

The surrounding fault factors, such as wiring, grounding, power distribution capacity and welding process used, shall be eliminated before removal. The removal can only be carried out after the internal fault of the welding machine is determined. Otherwise, the blind removal may make the special welding machine and equipment worse and worse, such as shielded metal arc welding, submerged arc welding, tungsten gas shielded arc welding, plasma arc welding and MIG welding.

3、先机后电

3. Power before power

检查焊接专机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 the mechanical components and parts, lubrication, air circuit, water circuit and oil circuit system of the special welding machine have problems. Only after confirming that these systems are free of faults, carry out electrical inspection.

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。

When checking the circuit fault, use detection instruments and meters to find the fault location. After confirming that there is no bad contact fault, check the operation relationship between the line and the machine in a targeted way to avoid misjudgment, such as spot welding, seam welding, projection welding, butt welding and other equipment.

所以说当确定故障部位后再进行检修和更换，解决产生的故障，使焊接专机设备尽快投入使用，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咨询吧！

Therefore, the repair and replacement shall be carried out after the fault location is determined to solve the fault, so that the special welding machine can be put into use as soon as possible and reduce the economic losses caused by the equipment fault.
