It is particularly important to note that when inspecting the internal or external connector terminals of a Shandong welding machine, it is necessary to turn off the input power switch before performing the inspection. Let's talk about its maintenance methods.
1. Conduct regular testing work
For example, check whether the cooling fan rotates smoothly when the welding machine is powered on; Whether there are abnormal vibrations, sounds, and odors; Whether there is any leakage of gas; Check whether the joints and insulation of the welding wire are loose or peeling off; Check whether there is abnormal heating phenomenon in the welded cable and various wiring parts.
Regularly use clean and dry compressed air to blow and wipe away the accumulated dust inside the welding machine
Due to the forced air cooling of the welding machine, it is easy to inhale dust from the surroundings and accumulate inside the machine. Therefore, we can regularly use clean and dry compressed air to purge the accumulated dust inside the welding machine. In particular, the gap between transformers, reactance coils, and coils, as well as power semiconductors, should be particularly cleaned.
Regularly inspect the wiring parts of the power wiring
Check whether the connection screws at terminals such as the input side and output side, as well as the connection parts of external wiring, and the connection parts of internal wiring, are loose. When rust occurs, remove the rust to ensure good contact conductivity.
4. Implement the replacement of defective parts and shell repair
The long-term use of special welding machines can inevitably cause deformation and rust to the shell due to contact, resulting in damage to the internal parts. Therefore, during annual maintenance and inspection, it is necessary to implement comprehensive repair work such as replacing defective parts, repairing the shell, and reinforcing the insulation deteriorated parts. The replacement of defective parts during maintenance can ensure the performance of the welding machine by replacing them with new ones all at once.
The regular maintenance and inspection implemented above can reduce the occurrence of welding failures. Although it requires some time and effort, it can prolong the life of welding equipment, improve the efficiency of operations, ensure the performance of special welding machines, and improve safety. It is an important content that cannot be ignored in welding work. If you have any doubts or needs, please contact us http://www.tayfsk.com Come on!
