1. Hydraulic station for WP110A to WP355A should be installed indoors and should have reliable zero connection protection. When multiple Hydraulic stations for WP110A to WP355A are installed side by side, the distance between the phases should not be less than 3m, they should be connected to the power grids of different phases, and should have their own knife switches.

2. The power lead of the welding machine should not be too thin or too long, the voltage drop during welding should not be greater than 5% of the initial voltage, and the initial voltage should not deviate from ±10% of the power supply voltage.

3. After the welding machine is installed, use a 500v megohmmeter to test the insulation resistance between the high-voltage side of the coil and the ground, which is not less than 2.5 megohms.

4. Operators should pass the physical examination and have no diseases or physical defects that hinder the operation, and should go through professional training, pass the examination and obtain the operation certificate before they can work with the certificate. Students should work under the guidance of a professional.

5. Operators and cooperating operators should wear gloves, aprons and protective glasses during work to avoid sparks flying out and scalding.

6. Before welding, check and confirm that the hydraulic station for WP110A to WP355A has a flexible pressure mechanism, firm fixtures, and no leakage in the cooling system. Only after everything is normal can welding be performed.

7. The end face of the weldment shall be processed during welding, and the weldment shall not be rusted to ensure good contact. The secondary voltage shall be adjusted according to the section of the welded steel bar, and the steel bar with a diameter exceeding the specified diameter of the Hydraulic station for WP110A to WP355A shall not be welded. Oxidation and slag inclusion, the top breaking force should be appropriate, and the top breaking speed should be as fast as possible, usually reaching 4-5mm/s.

8. The contact points and electrodes of the circuit breaker should be polished regularly, and all the connecting bolts of the secondary circuit should be tightened regularly. The cooling water temperature should not exceed 40℃; the drainage should be adjusted according to the temperature.

9. When welding long steel bars, brackets should be set up to cooperate with the operator who transports the steel bars, and sparks should be prevented during welding.

10. There should be no baffles in the flash area, and persons unrelated to welding are not allowed to enter.

11. When welding in winter, the indoor temperature should not be lower than 8 ℃. After the operation, the cooling water in the machine should be drained.

12. After the work is completed, the residues on the working surface should be cleaned up in time, and stored in the specified location, and should not be discarded at will to prevent soil pollution.
