How can the induction heating furnace be turned on and off to be safe?

1. Start-up procedure of induction heating furnace

(1) Turn on the water pump and check whether the water outlet pipelines are unblocked. Only when the waterway is unblocked can we proceed to the next step.

(2) Turn on the “Control Power” button, the corresponding indicator light is on (green light is on).

(3) Press the “AC Close” button, the corresponding indicator light (green light is on).

(4) Turn the “power adjustment potentiometer” counterclockwise to the end, and then press the “MF Start” button, the corresponding indicator light is on (green light).

(5) Slowly rotate the “power adjustment potentiometer” knob clockwise, and continue to increase the voltage when you hear the mid-frequency howling, and increase the mid-frequency voltage to 300V. At this time, the DC voltage is about 200V. The intermediate frequency voltage quickly rises to the rated value (usually 720V when the incoming line is 380V).

(6) If there is no IF whistling sound, only the DC ammeter has indication in the indicator, indicating that the IF has not been established, and the voltage cannot continue to rise at this time. You can turn the potentiometer counterclockwise to the end (ie “reset”), restart, and straighten. If the stop is successful, if it fails to start after 3 times, it must be shut down for inspection.

(7) You can also turn the “Adjust Potentiometer” knob to the required normal use position, and then press the “Intermediate Frequency Start” button to start automatically.

2. Shutdown procedure of induction heating furnace

(1) Rotate the power adjustment potentiometer counterclockwise to the end.

(2) Press the “Intermediate Frequency Stop” button, and the “Intermediate Frequency Start” indicator light is off.

(3) Press the “AC Open” button, and the “AC Close” indicator will go out at this time.

(4) Turn off the “Control Power”, at this time the “Control Power” indicator is off.

(5) At this time, the cooling water of the power supply can be turned off, and the cooling water of the sensor etc. can be turned off after the furnace is filled with people and cooled
