User Manual
- Rated Voltage: 220V/380V
- The installation process to avoid knocking, to avoid the damp, hand-held stove wire, they should wear gloves. Wire should be installed after the furnace has remained flat, and prevent surface scratches, dirt, corrosion, or improper installation, by affecting the life of
- In the rated voltage to use. In strong reducing atmosphere, acid atmosphere, an atmosphere of high humidity will affect the use of life;
- Temperature before use should be in dry non-corrosive atmosphere, about 1000 ℃ spend a few hours, so that furnace wire protective film formed on the surface after normal use, so that can guarantee the normal life of furnace wire;
- Furnace installation should ensure that the insulated wire good power to avoid touching furnace after the wire, guard against electric shock or burns.
