Heating element use precautions

1. The components should be stored outside of the dry. If the insulation resistance drops below 1 megohm due to long-term placement, it can be dried in an oven at about 200 °C for several hours (or the component is low pressure for several hours), ie, the insulation is restored. resistance.

2. When it is found that there is carbon deposit on the surface of the pipe, it must be used after being removed to avoid reducing the efficiency and even burning the components.

3. When melting solid oil such as asphalt and paraffin, the voltage should be reduced, and then increased to the rated voltage after melting. To prevent power concentration and reduce component life.
