What are the common faults of Electrofusion welding machine?

1. Power failure: including power failure, unstable voltage, poor contact of power plug, etc.
2. Display screen failure: For example, the display screen is not bright, the display is blurred, the display is garbled, etc., which may be caused by damage to the display screen itself, loose connection lines or control board failure.
3. Abnormal welding parameter setting: Unable to accurately set parameters such as welding current, time, voltage, etc., or cannot be saved after setting.
4. Unstable output current: Leading to poor welding effect, it may be due to aging, damage, or poor heat dissipation of internal circuit components.
5. Overheating protection failure: The equipment frequently triggers overheating protection during normal operation, or the overheating protection fails, which may be due to temperature sensor failure or abnormal heat dissipation system.
6. Welding electrode failure: The electrode is worn, deformed, and corroded, affecting the contact with the pipe fittings, resulting in poor welding.
7. Control board failure: Damage to components such as chips, capacitors, resistors, etc. on the control board may cause the equipment to fail to start, run, or control function to fail normally.
8. Communication failure: If the Electrofusion welding machine has the function of communicating with a computer or other device, communication interruption, data transmission error, etc. may occur.
