The first thing that should be given special attention is that when checking the connecting terminals inside or outside the welding machine, the power must be turned off.
1. Check regularly; for example, check if the cooling fan rotates properly when the welding machine is on; whether there are bad vibrations, sounds and smells; or gas; whether the joint material and the covering of the welding wires are loose or peeling; whether the welding wires are loose or peeling and whether there is abnormal heat at any joint.
2. 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 use clean and dry air regularly to remove dust in the welding machine. In particular, parts such as transformers, reactors, gaps between coils, and electronic control devices must be especially clean.
3. Always check the location of power line wires. Check whether the terminal screws on the input side, output side, etc., parts of external wiring, parts of internal wiring, etc. are loose. If there is rust, remove it and ensure good contact conductivity.
4. Long-term use of the welding machine will inevitably cause the outer casing to become deformed, rusted and damaged due to contact, and the internal parts will also wear out. Therefore, during the annual maintenance and inspection process, comprehensive repairs should be carried out, such as replacing faulty parts, repairing the housing, and strengthening parts with damaged insulation. Defective parts can be replaced with new products immediately during maintenance to ensure the functionality of the welding machine.
The above regular maintenance and inspection can reduce the number of welding failures, which require time and labor, but can extend the life of the welding machine, improve operating efficiency, ensure the performance of handheld laser welding machine and improve safety. which cannot be ignored when welding. important content.
