What are the key points of using the electric heating jacket? The newly bought electric heating mantle will emit white smoke and peculiar smell when it is used for the first time.
Why is this? This phenomenon is related to the material of the braided electric heating sleeve.
Because the electric heating sleeve contains glass fiber plus oil and other compounds in the production process, users need not be afraid.
It can be used normally after disappearing in a few minutes
.

Precautions when heating the heating mantle 1.
The instrument should be well grounded
.

2.
When using for the first time, white smoke and peculiar smell emerge from the sleeve, and the color changes from white to brown to white.
It can be used normally after disappearing in a few minutes
.

3.
The squeaking-squeaking sound of the heating mantle above 3000ml is due to the different structure of the furnace wire and related to the thyristor voltage regulating pulse signal, so it can be used with confidence
.

4.
If it is found that there is no power supply, please first check whether the right rear insurance needs to be replaced
.

5.
Please do not use empty sets for heating or empty heating
.

6.
When there are wet hands, liquid overflow or long-term exposure to excessive humidity, there may be induced electricity transmitted to the shell through the insulation layer.
Please be sure to ground the wire and pay attention to ventilation
.

If the leakage is serious, please don't use it again, you need to put it in the sun or dry it in the oven before use, so as to avoid danger
.

7.
When not in use for a long time, please keep the instrument clean and store it in a dry and non-corrosive place
.

The above is the relevant introduction about the key points of the use of the electric heating plate.
I believe that everyone has a corresponding understanding of this after reading it.
After mastering the relevant matters, it may greatly reduce the damage to the instrument due to improper operation.
I hope it will be helpful to everyone
