Ten daily maintenance knowledge of spot welding machine

spot welding machine should do a good job of cleaning after the operation is completed, because with the increase of welding spots, some white medium will accumulate between the upper and lower electrodes, and when this medium accumulates to a certain extent, the resistance will increase, which is the most unfavorable to the quality of welding spots, so daily cleaning becomes especially important. Here are some commonly used cleaning and maintenance knowledge.

1. Before use, check whether the equipment is running normally. After power on, run for a period of time and observe carefully. If there is no abnormal sound, the equipment is functioning normally.

2. Check whether the electrodes of the welding machine are on the same horizontal plane. If oxidation or blackening occurs, the electrodes should be polished with sandpaper.

3. When using the intermediate frequency spot welding machine, observe that the spot welding products do not have the phenomenon of fire and blackening. If so, the welding machine needs to be debugged.

4. Check whether the cooling water is blocked, and find and remove the scale or blockage in the water pipe in time.

5. The compressed air input into the spot welding machine is required to be clean and dry. Excessive moisture or corrosive substances in the compressed air will affect the working life of the solenoid valve and the cylinder or even not work. Too low air pressure can not guarantee the welding quality, and too high air pressure will cause damage to the air source processing parts of the spot welding machine.

6. Check whether the reduction gearbox is filled with lubricating oil. If any abnormality is found, it shall be handled according to the maintenance specification of the reduction gearbox.

7, adjust the appropriate parameters (worktable rotation speed) and correct steering, start the equipment for normal operation and operation.

8. Anti-burn: There will be metal splash during welding operation, especially when the workpiece is uneven (especially when welding high-power large workpieces). Therefore, the operator should wear protective glasses to prevent burns.

9. Regularly check the wiring parts of the power wiring, the terminals on the input side and the output side, as well as the wiring parts of the external wiring, and whether the wiring screws on the wiring parts of the internal wiring are loose. If they are damaged or loose, they need to be replaced in time.

10. It is necessary to add oil to the oil mist regularly to keep the oil level within the required range and to release the dust in the air filter.
