How is it that the heating plate always burns solid?

If the heating plate always burns solids, there may be the following reasons:

1. Temperature setting is too high: check whether the temperature setting of the heating plate is too high. If the temperature is set too high, the heating plate will exceed the melting point of solid materials, resulting in sintering or scorching.

2. Failure of heating plate: Check whether there is any failure of heating plate, such as damage of temperature sensor or control circuit. If the heating plate cannot accurately control the temperature, it may lead to overheating.

3. Too long heating time: If the solid material stays on the heating plate for too long, it may also lead to overheating and solid combustion. Ensure that the heating time is appropriate and avoid too long heating time.

4. Improper selection of materials: Some materials are easy to burn into solid on the heating plate, especially some flammable or low melting point materials. Make sure to choose suitable materials for the heating plate and avoid using inappropriate materials.

If the heating plate always burns solids, it is suggested to check the setting and state of the heating plate to ensure normal temperature control, proper heating time and selection of suitable materials. If the problem still exists, it is best to contact professional and technical personnel for maintenance.
