The intermediate frequency inverter spot welding machine may encounter some minor malfunctions during use. Resolving these faults typically requires inspection and maintenance of the equipment. Here are some common minor faults and their solutions:
Reason: electrode contamination or wear, improper welding parameter settings, unclean workpiece surface.
resolvent:
Clean or replace the electrode to ensure a smooth and dirt free surface.
Adjust welding parameters, including current, time, and pressure, to ensure suitable welding conditions.
Clean the surface of the workpiece to remove grease, oxides, and other impurities.
Reason: Cooling system malfunction, excessive electrode pressure, and long welding time.
resolvent:
Check the cooling system to ensure that the cooling water is flowing properly and the water temperature is appropriate.
Adjust the electrode pressure to avoid excessive pressure causing the electrode to overheat.
Adjust the welding time to avoid excessive welding time.
Reason: Loose electrode fixture and inaccurate positioning device.
resolvent:
Check and tighten the electrode fixture to ensure it is secure.
Adjust the positioning device to ensure electrode alignment.
Reason: Fluctuations in power supply voltage and poor contact of welding cables.
resolvent:
Check the power supply voltage to ensure stable power supply.
Check the welding cable to ensure a secure connection without looseness or poor contact.
Reason: Controller malfunction, loose or broken connection lines.
resolvent:
Check the controller to ensure it is functioning properly, and restart or replace it if necessary.
Check the connecting wires to ensure they are not loose or broken.
Reason: Loose fixture, irregular shape of workpiece.
resolvent:
Check and tighten the fixture to ensure that the workpiece is firmly clamped.
For irregularly shaped workpieces, use appropriate fixtures for fixation.
Reason: Excessive current and improper welding parameter settings.
resolvent:
Adjust the welding current to ensure it is appropriate.
Reset welding parameters, including time and pressure.
Reason: Excessive welding current, long welding time, and unsuitable workpiece material.
resolvent:
Reduce welding current and time to avoid excessive heating.
Choose suitable welding materials and processes.
preventive measure
Regular maintenance is very important to reduce the occurrence of malfunctions. Here are some preventive measures:
Regularly inspect and clean the electrode and workpiece surfaces.
Regularly inspect the cooling system to ensure its proper operation.
Regularly check the connection status of the power supply and welding cables.
Regularly inspect and adjust welding parameters to ensure that the equipment is working in optimal condition.
By promptly identifying and resolving these minor faults, the efficiency and welding quality of the intermediate frequency inverter spot welding machine can be effectively improved.
