No-load Current Detection Process of High Frequency Plastic Welding Machine

In the production and processing process of high frequency plastic welding machine, high frequency plastic welding machine no-load current detection is very important when high frequency molds are replaced or high-frequency failure occurs. No-load current detection can detect the failure of the high frequency plastic welding machine equipment in time, and ensure the normal operation of the high frequency plastic welding machine equipment.


How to correctly operate the high frequency plastic welding machine no-load current detection process and method are as follows:


1. Adjust current of high frequency plastic welding machine


First, adjust the coherent that controls the current of the high frequency plastic welding machine to "0" to ensure the minimum current output.


2. The gas source of the high frequency plastic welding machine is cut off


Raise the upper pressure plate of the high frequency plastic welding machine equipment to the highest position, and disconnect the air input of the two-piece unit. (Note: The upper plate of some manufacturers' equipment will drop directly after the air is cut off. Pay attention to safety during operation. If the equipment is this phenomenon, it is recommended to pad a piece of dry wood with a height of about 10 cm on the workbench.)


3. Adjust the time of high frequency plastic welding machine


If it is due to equipment failure of the high frequency plastic welding machine that needs to be tested without load, we can adjust the "welding time" to about 1 second to shorten the time to ensure the safety of the high frequency plastic welding machine.


4. High frequency plastic welding machine passes high pressure


After ensuring that the above three points are done, you can use an insulated screwdriver to control the limit switch to close, and listen carefully for the sound of the "AC contactor".


5. Observation ammeter of high frequency plastic welding machine


After listening to the sound, we immediately observed the swing position of the ammeter pointer. Under normal circumstances, the no-load current of the high frequency plastic welding machine is about 0.2aA. If the ammeter does not move or the pointer of the ammeter immediately returns to the bottom, it indicates that the high frequency plastic welding machine is faulty. Then analyze the problem of high-frequency barriers according to the swing direction of the ammeter pointer.
