The no-load current of Ultrasonic Plastic Welding machine refers to the no-load current value displayed on the ammeter when the welding head is in the rising state and the product is not welded, when the sonic test button is pressed, and when the current exceeds 1a, it means a certain part If there is a problem with the equipment, it must be solved in time, otherwise it is easy to damage the entire equipment. So how to solve the problem of excessive no-load current in ultrasonic welding? First of all, we need to consider that the reasons for the excessive current of Ultrasonic Plastic Welding machine are as follows:
1. The welding head is not completely fixed or locked. In this case, solving the problem is very simple. Lock the welding head.
2. The sound frequency adjustment is inappropriate. Using the unit's acoustic check function, adjust the sonic screw to minimize the indicated current value.
3. The mold size is not suitable or the mold is broken. Replace the mold in time, because the mold increases the no-load current.
4. The power tube or power amplifier is faulty. Check the working condition of the transmission pipes and circuits.
