PID Control System

The PID module is function to measure and to control the heating.

The temperature measurement in the heating coil is made at regular intervals.

The information is transmitted to the PID module as current value. If the current value is inferior to the set value, the PID module makes the device heat. If the current value is superior or equal to the set value, the PID module stops the heating.

This cycle gets repeated at a 2-second-interval. Therefore, a high grade of precision is ensure.

The advantages of the PID module in comparison to a normal thermostat are the flexibility,the efficiency and the precision.

Thus, the energy consumption can be optimized, and the material fatigue can be compensated.

Kindly Notice:

When the machine has worked continuously for 2 hours, please turn it off to cool down for 30 minutes, to ensure a long durability and a good function.

Periodically check the intactness of the crucible to avoid damages of the heating coil.

The maximal operating temperature tolerated by the melting furnace is 1150?, never exceed this value.

The graphite crucible is only adapted to melt gold, Silver, copper and other sev noble metals.

Recycled gold or silver contain acid and alkali which may corrode the heating element. If you want to melt that kind of metals, please open the cover of the melting chamber with regularity to let the toxic substances evaporate.
