Ultra high power fiber laser cutting machine manufacturer laser hand welding machine daily maintenance. First of all, it should be noted that the input power switch must be turned off before checking the internal or external connector terminals of the welder.

1. Do a good job of regular testing. For example, check whether the cooling fan rotates smoothly when the welding machine is energized, and whether there is abnormal vibration, sound and smell; Whether there is a gas leak; Whether the welding wire joint and insulation wrap are loose or fall off; Welding cable and wiring part is abnormal heating phenomenon.

2. Due to the forced air cooling of the welder, it is easy to inhale dust from the surrounding and accumulate in the machine. Therefore, we can periodically use clean and dry compressed air to wipe the dust that accumulates inside the welder. In particular, the gaps between transformer, reactive coil and coil, power semiconductor and other components should be cleaned.

3. Periodically check the wiring part of the power cable. If the screws on the input and output terminals that can absorb external and internal cables are loose, remove rust to ensure good contact conductivity.

4. Long-term use of welding machine will inevitably cause shell deformation, rust, damage and wear of internal parts. Therefore, during the annual maintenance and inspection period, a comprehensive repair work such as replacement of defective parts, enclosure repair and reinforcement of insulation deteriorated parts is required. Replacement of defective parts during maintenance, all new products can be replaced at one time to ensure the performance of the welder.

The above regular maintenance and inspection can reduce the occurrence of welding failures. Although it takes some time and effort, it can extend the welder's life, improve work efficiency, ensure the welder's performance and improve reliability. This is the important content of welding work can not be ignored.
