3kg Electric Melting Furnace to melt Gold Silver and Copper DEMO UNIT

Premium Melting Furnace: This electric melting furnace with a 3 kg capacity has a high temperature-proof ceramic melting chamber, the quartz lid and inner tank, and a graphite crucible. It can be heated quickly within 45 minutes to melt metals entirely.

High-Quality Crucible: The crucible is made of pure graphite to melt high-purity precious metals. With excellent thermal conductivity properties, this crucible significantly shortens the melting time. Besides, the groove design facilitates the pouring and filling of the melts.

Highly Advanced PID Module: The gold melting furnace is equipped with an advanced PID module, digital control system, and K - type thermocouple to provide you with accurate and convenient metal melting. The current temperature in the melting furnace is monitored every two seconds without overheating or cooling.

Complete Melting Kit: In this electric smelter set, we provide everything you need: a 3 kg graphite crucible, crucible tongs, power cable, and protective gloves. It's perfect for everyone, even for the beginner.

Wide Application: Our digital electric melting furnace can meet industry and workshop requirements and is suitable for processing precious metals such as gold, silver, and copper.

Important:
Led display with touchpad digital read out allowing precision temperature control.
New type melting furnace apply SSR controller, high temp proof ceramic melting chamber, high aluminium protection and other advanced, top quality components to improved it's durability and working efficiency over current markets furnaces.
Insulated lid holding heat in and keeping oxygen out for a more cleaner melting.
When using the graphite crucible some matters need to be paid attention to: because the bottom of the Crucible is very small, the crucible needs to be put on the graphite pad or mud triangle when heated. The graphite crucible can be directly heated and cannot be cooled immediately after heating. Take it off with a Crucible clamp and do not put it on a cold metal table to avoid its rupture due to rapid cooling.Do not put it on a cold metal table to prevent it from cracking due to sharp cooling.
This is specially designed and constructed for melting metals for casting and alloying. Some of the Metals that can be melted with this Furnace : Aluminum, Copper, Gold, Lead, Silver, Sterling Silver, Tin & Zinc.

READ THE INSTRUCTION BOOKLET PROVIDED

• Maximum Melting Temperature 1150° C
• Do not exceed 70% of the maximum capacity of the crucible. Overloading the crucible will prevent the crucible from reaching the desired temperature
• Before use, preheat the machine and crucible to 300-500 °C for 3-5 minutes. This prolongs the life of the crucible.
• After preheating the machine, set the desired melting temperature and wait for the metal to meltThe maximum working time of the furnace is 3 hours. Once you reach 3 hours, the machine must be switched off and allowed to cool for a minimum of 3 hours.Do not move the furnace after using it. The furnace must cool for between 3 and 5 hours.
• Moving the furnace before it is completely cooled will crack the heating core.
• Cracks in the inner ceramic pot will occur due to the temperature fluctuations experienced during use. This is normal, does not affect the use of the machine, and it may continue to be used.
• The heating and melting process takes about 48 to 60 minutes.
