1.2 General safety information for the use of melting furnaces:
●The user manual should be kept close to the device and should always be accessible to
the users. Instruct your employees on how to use the melting furnace properly.
● Make sure your working area is well aerated.
● Keep the escape routes clear.
● Keep a fire extinguisher ready for use.
● Always use safety gloves.
●Do not place melting furnaces on combustible supports or close to combustible materials.
●Do not let the device be without surveillance during the heating.
●Do not overfill the crucible, in order to prevent it from overflowing during the heating.
●Add solid melting materials by inserting them slowly into the hot liquid mass.
1.3 Specific safety information for the use of melting furnaces:
●In order to ensure long durability and good function of your device,
we strongly advise you to work less than 3 hours once. Please ensure to
stop for 30 minutes after 2 hours of continuous work.
●The maximal operating temperature tolerated by the melting furnace is 1150℃. Never
exceed this value.
●Recycled gold or silver contains acid and alkali which may corrode the heating element. If
you want to melt that kind of metal, please open the cover of the melting chamber with
regularity to let the toxic substance evaporate.

Please consider that the crucible shouldn't be completely filled to reach an optimal
result. If you overfill the crucible, the device won't be able to produce the heat
needed to let the metal melt. Moreover, the melting process often produces vapors.
If you overfill the crucible, it can lead to over pressure and the use of the device
gets dangerous for the user, at the latest by opening the cover.
Please buy an adapted crucible to melt other metals. Always inform yourself about
the production of vapors during the melting process to check the compatibility of
the device with your intentions.
HOW TO DETECT HEATING COIL
CAUTION: Never open the device without the authorization of your seller.
The heating coil may get damaged, and you have to exchange it.
To do it, please follow these given instructions: Check the function of the
heating coil.
1. First open the bottom of the furnace.
- 11 -
2. Check the resistance of the heating coil like this.
NOTE: The resistance is about 8.7Ω. If there is no resistance, the heating
wire is broken, and you need to change a new heating coil.
REPLACE THE HEATING COIL
1. Remove the heating wire connector and remove the two bolts.
2. Open the screws on the stainless steel and remove the cover.
- 12 -
3. You can take out the thermal insulation wire cylinder.
Put on the new heating wire cylinder, and install the heating wire cylinder
back according to the steps previously removed.
MATTERS NEEDING ATTENTION
Display error codes to determine machine problems
●ERR1:The temperature measuring circuit on the board is broken
●ERR2:The thermocouple is broken or not connected
●ERR3:Thermocouple temperature measurement is out of range
●ERR4:The temperature sensing element on the board is broken or falls off
●ERR5:The fan is broken or falls off
●ERR6:The temperature control element is high

NOTE:
1. Metal material falling into the heating wire cylinder short circuit, in the
work of the crucible broken metal flow heating wire cylinder burned off.
This you need to buy a replacement heating wire cylinder.
2. After pressing the P key, the upper right corner flashes on the beginning
of heating, and it can be judged that the heating wire is burned off if it is not
heated within one minute.
MAINTENANCE
1. Clean the exterior and interior regularly to avoid impurities and metal
residues.
2. Before and after use, you need to check whether the device is normal.
