How to Maintain the Welding Machine

Every enterprise or individual engaged in welding work hopes to give full play to the performance of the equipment and extend the service life of the machine. To achieve this purpose, in addition to using the welding equipment correctly according to the operating procedures, regular maintenance and repair work is also important. The following are the main points of maintenance of the welding machine.

1. First of all, it should be noted that when checking the connector terminals inside or outside the welder, the power supply switch must be turned off before doing.

2. Regularly do the inspection work. For example, check the welding machine power, whether the cooling fan rotation is smooth; whether there are abnormal vibrations, sound and odor; gas leakage; whether welding wire joints and insulation wrapping are loose or peeling; whether the welding cable and the wiring parts is any abnormal heat phenomenon.

3. If the welder is air-cooled, it is easy to absorb dust from the surrounding and accumulate it inside the machine. Therefore, we can regularly use clean and dry compressed air to blow away the dust inside the welder. Especially the transformer, reactor coil, the gap between the coil and windings, and power semiconductor and other parts should be cleaned.

4. Regularly check the wiring locations of power wiring. Check whether the wiring screws on the input side, output side terminals, as well as the external wiring of the wiring parts, the internal wiring of the wiring parts, and other parts of the wiring screws whether there is loosening. If there is rust, remove the rust to make the contact conductive well.

5. Long-term use of the welder will inevitably cause the shell to be deformed due to collision, rust, and damage, and the internal parts will also wear, so during annual maintenance and inspection, defective parts must be replaced, the shell repaired, and the insulation deteriorated parts repaired. Comprehensive repair work such as reinforcement. When replacing defective parts during maintenance, it is best to replace them with new ones at once to ensure the performance of the welding machine.

The above-mentioned regular maintenance and inspection can reduce the occurrence of welding faults, although it takes some time and effort, the life of the welder can be extended, and can enhance the efficiency of the operation, to ensure the performance of the welder and improve safety. It is an important content of welding work that cannot be ignored.
