How to detect if the current is normal when the above phenomenon occurs?

1. Observe whether the electronic tube lights up on the homepage and use high-frequency fuses;

2. Disconnect the gas source, start the high-frequency switch, and observe whether the pointer of the high-frequency ammeter is at 0.2A;

3. If the ammeter does not display, you can check whether the gate resistance is normal or observe whether the AC contactor is engaged and working;

4. If the ammeter displays and automatically rotates the high-frequency machine at 0.2A, it can detect the phenomenon of sparking in the mold or capacitor;

5. Observe whether the welding time indicator light can bounce the high-frequency fuse according to the adjustment time value;

The main reasons for high-frequency machines and high-frequency machines suddenly not heating up during normal use are as follows:

1. The communication contactor is not engaged, and the high-voltage LH-500DG cake box bottom rapid prototyping machine is not connected

2. The welding time system is damaged and the time does not work

3. Electronic tube malfunction, filament not lit or damaged

4. In spark protection, the mold or capacitor is short circuited

5. High frequency start-up, PVC cylinder forming mechanism damaged, high-frequency fuse machine

6. The gate resistor is damaged and the ammeter is not functioning.
