设备电路或焊接设备的故障大致归纳为短路、过载、断路、接地、接线错误、焊接设备的电磁及机械部分故障、元器件老化等七类。诸类故障中出现较多的为断路故障，包括导线断路、虚连、松动、触点接触不良、虚焊、假焊以及熔断器熔断等。

The faults of equipment circuit or welding equipment can be roughly divided into seven categories: short circuit, overload, open circuit, grounding, wrong wiring, electromagnetic and mechanical part faults of welding equipment, aging of components and parts. Many of these faults are open circuit faults, including wire open circuit, virtual connection, looseness, poor contact of contacts, false soldering, false soldering and fuse fusing.

对山东自动焊接设备的这类故障除用电阻法、电压法检查外，还有一种更为简单可靠的方法，就是短接法。即用一根良好绝缘的导线，将所怀疑的断路部位短路接起来，如短接到某处，电路工作恢复正常，说明该处断路。具体操作可分为局部短接法和长短接法。

In addition to the resistance method and voltage method, there is a simpler and more reliable method to check such faults of Shandong automatic welding equipment, that is, the short-circuit method. That is, use a well insulated wire to short-circuit the suspected open circuit part. If it is short circuited to a certain place, the circuit will return to normal, indicating that there is an open circuit. The specific operation can be divided into local short connection method and long short connection method.

对于连续烧坏的元器件应机明原因后再进行更换；电压测量时应考虑到导线的压降；不违反设备性能和焊接设备作用的原则，修复的焊接设备初次试通电工作前，

The components and parts that are continuously burnt out shall be replaced after the cause is found out; The voltage drop of the conductor shall be considered during voltage measurement; Do not violate the principle of equipment performance and the role of welding equipment. Before the first trial energization of the repaired welding equipment,

对气体保护焊和点焊、缝焊、凸焊及对焊等设备应该先通气、通水，应该加油的部位还需要加油，周围障碍物，通电工作时手不得离开电源开关停止按钮，保险期间应使用等量或略小于额定值的电流；还须注意测量仪器仪表挡位的选择。

Gas shielded welding, spot welding, seam welding, projection welding, butt welding and other equipment should be ventilated and watered first. The parts that should be oiled also need to be oiled, and the surrounding obstacles should be removed. When working with power on, hands should not leave the power switch stop button. During the insurance period, the same amount of current or slightly less than the rated value should be used; Attention should also be paid to the selection of gear of measuring instruments.

以上一些检查方法，要视情况灵活运用，但须遵守操作规章，防止在设备维修过程中出现人身、设备伤害事故，并且尽可能两人操作和监护。

The above inspection methods should be used flexibly according to the situation, but the safety operation rules must be observed to prevent personal and equipment injury accidents in the process of equipment maintenance, and two people should operate and monitor as much as possible.

对焊接设备故障的检查和维修排除，要按照相关要求做好记录。方便以后类似故障发生后的检查、日常维护保养和故障排除的经验积累，更多相关内容就来我们网站http://www.tayfsk.com咨询了解吧。

The inspection, maintenance and troubleshooting of welding equipment shall be recorded according to relevant requirements. It is convenient to accumulate experience in inspection, daily maintenance and troubleshooting after similar faults occur in the future.
