What is the reason why the vacuum sintering furnace does not operate when it is started?

It may be that the main power supply is not connected properly. Check the connection status of the external power supply of the device. Check the control power supply, use the key to turn on the power supply or close the switching power supply in the power distribution cabinet. Try to press the emergency stop button, roll out the emergency stop button if you can’t press it. It may also be that the power cord or other equipment is damaged, and the vertical power source of the vacuum sintering furnace must be reconnected.
