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.
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) Preliminary inspection
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) Test welding
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.
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.
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.
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.
