直观法是根据焊接专机等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。下面来讲讲该设备的维修检查步骤内容吧。

Visual method is a method to check and judge the fault by means of seeing, smelling and listening according to the external performance of the fault of electrical components such as welding machine. Let's talk about the maintenance and inspection steps of the equipment.

1）调查情况

1) Investigation

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。

Ask the operator and the personnel on site when the fault occurs, including the external performance of the fault, the approximate position and the environmental conditions when the fault occurs. For example, whether there is abnormal operation, open fire, heat source, etc., whether it is close to electrical components, whether there is corrosive gas intrusion, whether there is water leakage, whether someone has repaired it, and the content of repair.

2）初步检查

2) Preliminary inspection

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。

According to the investigation, check whether the external of relevant electrical components are damaged, whether the wiring is broken or loose, whether the insulation is burnt, whether the fusing indicator of the screw fuse jumps out, whether the electrical components have water and oil dirt, and whether the switch position is correct.

3）试焊

3) Test welding

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。

After preliminary inspection, it is confirmed that there is no possibility to further expand the fault and cause personal and equipment accidents, it can be powered on.

稳定无异常情况后，可进一步做焊接试验检查，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。

After it is stable and free of abnormal conditions, further welding test and inspection can be carried out. During normal operation of the welding machine, attention should be paid to whether there are serious diving, abnormal smell and abnormal sound. Once found, it should be stopped immediately and the power supply should be cut off.

山东焊接专机厂家提醒您，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。

Shandong welding machine manufacturer reminds you to check whether the temperature rise of electrical components and the action procedure of electrical components meet the requirements of the schematic diagram of welding equipment, so as to find the fault location.

注意，设备使用后，应及时检查附件，设备油污，保证库内指定位置清洁放置。要定期对设备进行检备，补充润滑油，以上内容希望给您帮助，更多内容就来我们网站http://www.tayfsk.com进行咨询吧。

Note that after the equipment is used, the accessories should be checked in time to remove the oil stain on the equipment and ensure that the designated position in the warehouse is clean and placed. We should regularly check and prepare the equipment and replenish lubricating oil. I hope the above content can help you.
