焊接专机在经过一段时间的使用后，总会因为种种原因出现故障。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。下面来讲讲山东焊接专机的直观检查方法吧。

After a period of use, welding machines will always malfunction due to various reasons. After determining the fault location, maintenance and replacement should be carried out to solve the resulting faults, so that the welding equipment can be put into use as soon as possible and reduce the economic losses caused by equipment failures. Next, let's talk about the visual inspection method of Shandong welding machine.

直观法是根据电器元件故障的外部表现，通过看、闻、听等手段检查判断故障的方法。维修检查步骤：

The intuitive method is a method of checking and judging faults based on the external manifestations of electrical component faults through means such as seeing, smelling, and listening. Maintenance and inspection steps:

①调查情况：向操作者和故障发生时的在场人员询问情况，包括故障外部表现、大致部位以及发生故障时的环境情况。如有无异常操作、明火、热源等是否靠近电器元器件、有无腐蚀性气体侵入、有无漏水、是否有人修理过以及修理的内容等。

① Investigation situation: Ask the operator and the personnel present at the time of the fault, including the external manifestations of the fault, the approximate location, and the environmental conditions at the time of the fault. If there are any abnormal operations, whether open flames, heat sources, etc. are close to electrical components, whether there is corrosive gas invasion, whether there is water leakage, whether someone has repaired, and the repair content.

②初步检查：根据调查的情况，查看有关电器元器件外部有无损坏、连线有无断路、松动，绝缘有无烧焦，螺旋熔断器的熔断指示器是束跳出，电器元器件有无进水和油垢，开关位置是否正确等。

② Preliminary inspection: Based on the investigation, check whether there is external damage to the electrical components, whether the wiring is open or loose, whether the insulation is burnt, whether the fuse indicator of the spiral fuse is bundle jumping out, whether the electrical components have water and oil stains, and whether the switch position is correct.

③试焊：通过初步检查，确认没有可能使故障进一步扩大和造成人身、设备事故后，可以通电。稳定无异常情况后，可进一步做焊接试验检查，

③ Trial welding: After confirming through preliminary inspection that there is no possibility of further expansion of the fault or causing personal or equipment accidents, power can be applied. After stable and without any abnormal conditions, further welding test inspections can be conducted,

焊机在正常工作中要注意有无严重跳水、异常气味和异常声音等现象，一经发现应立即停止，切断电源。注意检查电器元器件的温升及电器元器件的动作程序是否符合焊接设备原理图的要求，从而发现故障部位。更多相关事项就来我们网站http://www.tayfsk.com咨询吧！

During normal operation of the welding machine, attention should be paid to whether there are serious diving, abnormal odors, and abnormal sounds. Once found, it should be immediately stopped and the power should be cut off. Pay attention to checking the temperature rise of electrical components and whether the action program of electrical components meets the requirements of the welding equipment schematic diagram, in order to identify the faulty part.
