Ultrasonic welding machines play a crucial role in industrial production. However, when the welding machine is turned on for normal welding operations, the overload protection device frequently starts soon after, causing the equipment to stop working and trigger again shortly after resetting, which not only affects production efficiency but may also cause further damage to the equipment. It is essential to understand the reasons and master the repair methods. If your ultrasonic welding machine experiences this malfunction, please feel free to consult with Youwo Ultrasonic. We can provide repair services for your company, promptly detect and solve these problems, effectively improve the reliability and production efficiency of the equipment, and ensure that the equipment is always in the best working condition.

Analysis of the frequent triggering of overload protection faults in ultrasonic welding machines

1. Power supply issue: Unstable power supply is one of the common reasons for frequent triggering of overload protection. Voltage fluctuations, damage to power lines, or poor contact can cause additional current loads on equipment during operation, triggering overload protection.

2. Overloading: The welded workpiece is too large or thick, exceeding the load-bearing capacity of the equipment. When the equipment attempts to complete welding tasks beyond its design load, it will trigger overload protection due to excessive load.

3. Excessive pressure: During ultrasonic welding, if too much pressure is applied, it can cause equipment overload. Unreasonable pressure settings or improper operation can lead to this problem.

4. Loose or damaged welding heads, amplitude converters, or transducers: These components may become loose or damaged after prolonged use, affecting the transmission of ultrasonic energy and leading to overload.

5. Excessive frequency deviation caused by insufficient power: When the power of the equipment is insufficient, it may lead to excessive frequency deviation, resulting in overload.
