Electric welding machine routine maintenance

1. Check the welding machine output wiring specifications, firm.
2. Check the screw fastening at the cable connection, the flat pad and the spring pad are complete, and there is no bad phenomenon such as rust and oxidation.
3. Check that the exposed cable length of the wiring is less than 10mm.
4. Check that the welder casing is grounded firmly.
5. Check the power supply of the welding machine and the grounding of the base metal.
6. Check the cable connection for reliable insulation and tape it.
7. Is the screen shield of the power cable, welding cable and welding machine wiring intact?
8. Whether the welding machine cooling fan rotates flexibly and normally.
9. Whether the power switch, power indicator and adjustment handle knob are kept intact, ammeter, voltmeter pointer is flexible and accurate, and the surface is clear and crack-free. The cover is intact and the switch is free.
10. Check the CO2 gas for leaks.
11. Check if the appearance of the welder is good and there is no serious deformation.
12. Check if the hexagon socket screws at the joint of the CO2 welding gun and the CO2 wire feeder are tightened and the CO2 torch is loose.
13. Check if the cable and air pipe of the CO2 wire feeder are wrapped and fixed.
14. Check the CO2 wire feeding device correction wheel and the wire feed wheel for timely replacement.
15. Check that the motor is fixed and the insulation coil is intact.
16. Check the remote control box on the CO2 wire feeder for looseness.
17. When installing the CO2 welding torch, tighten the welding torch switch plug and insert it into the guide groove. After the welding gun is installed, tighten the fastening screw.
18. Whether the welding tongs are damaged, whether the upper and lower casings are loose, affecting the insulation, whether the casing fastening screws are loose, and the cables are firmly connected and conductive.
19. Whether the welding machine wheel is complete and flexible.
20. Thoroughly clean the surface of the equipment once a week.
21. Every six months, use the compressed air (excluding moisture) inside the welding machine to remove the internal dust (must clean the power supply before cleaning). When removing dust, remove the upper and side plates, then blow them up and down in order, and wipe the grease with a cloth.
22. The maintenance project is undertaken by the operator.
