Automatic Electric Melting Furnace，2KG / 3KG Digital Melting Furnace Metal Kiln Refining Alloy Aluminum Gold Silver 110V (3KG Red)

---

Feature Product

• 2kg CRUCIBLE capacity; Power input:1500(w); Power supply: 110V, 50Hz; Max temperature is 1150℃/2102℉
• The top of the melting furnace machine is made of quartz stone, which is heat resistance, acid and alkali resistance and aging resistance
• The melting crucible comes with a melting tongs that fit into the groove around the crucible head, which allows you to work safely with the hot melt crucible
• Gold melting furnace is equipped with highly advanced PID module and digital control system to provide you precise and convenient metal melting, which monitors the actual temperature in the melting chamber at 2-second intervals so that it won't overheat or cool down
• This smelting furnace is ideal for professional use of the industry and the workshop, suitable for the processing of melting gold, sterling silver, pure copper and aluminium

Description

Control system: the PID
The PID module has two functions:to measure and to control the heating.
The temperature measurement in the heating coil is made at regular intervals.
The information is transmittde 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-intervall. Therefore, a high grade of precision is ensurde.
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 optimizde,and the material fatigue can be compensated.
Special attention:
· In order to ensure a long durability and a good function of your device, we strongly advice to work less than 3 hours at once. please ensure to stop for 30 mins after 2 hours of continuous work .
· 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.
· 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.
