  • describe:

  • Input power: 1600 (W); power supply: 110V, 50, 60 Hz/14A; maximum heating temperature: 1150°C (2102°F) furnace capacity: 3KG/6.6LB.
  • The furnace uses high-quality material-quartz stone (high temperature resistance, acid and alkali resistance, aging resistance).
  • The melting speed of the machine is very fast, the first melting time is 30 minutes, and the second time is generally about 15 minutes.
  • The melting furnace is equipped with advanced PID modules and digital control systems to provide you with accurate and convenient metal melting.
  • Graphite crucible is heat-resistant, efficient in heat preservation, and the temperature is uniform and constant during melting. It is professionally used for the processing of precious metals such as gold, pure silver, pure copper, and aluminum.
  • feature:
  • 1. Energy-saving high-purity fiber alumina chamber-chamber size: 60 mm dia. x 150 mm deep.
  • 2. Precise temperature control, easy-to-read digital display and LED on/off indicator.
  • 3. Single point temperature control? (Only temperature, does not control heating and cooling speed and residence time).
  • 4. Includes complete accessories, ready for immediate use,
  • Package Included:
  • 1 x electric furnace
  • 1 x graphite crucible
  • 1 x instruction manual
  • 1 x pliers
  • instruct:

  • 1. Connect power
  • 2. Turn on the O/N power switch
  • 3. Set the temperature (melting point temperature) under the normal display state of SV/PV, press the "set" button to make the SV display flashing, and each bit can be set.
  • Note: This machine has a display recovery function. When the operator forgets to return to the main display mode after performing operations such as parameter setting modification, the instrument will automatically return to the main display mode after 30 seconds, and the changed parameters will not be saved.
  • 4. When the furnace heats up, "OUT" will light up until the actual temperature reaches the set value.
  • 5. When the temperature reaches the set value, the furnace stops heating, the "OUT" light starts to flash, and the temperature continues to rise at this time.
  • 6. Pour the molten metal into the mold, and then put the crucible back into the furnace.
  • 7. If the entire smelting process has been completed, please turn off the power.
  • hint:

  • 1. Please do not open the instrument when it is wet. If the product gets wet, please dry it in the sun and put the instrument in a safe place to avoid damage to the equipment and other people.
  • 2. After the instrument has been working continuously for more than 3 hours, the standby unit should cool down before working. Do not place the machine near any heat-generating products.
  • 3. Please disconnect the power before cleaning, and wipe the parts to be cleaned with a soft damp cloth. Do not wipe with a damp cloth. Do not allow any liquid to enter the machine.
  • 4. If the metal to be smelted contains acids, alkalis and other substances, these substances will undergo chemical reactions at high temperatures and even corrode heating elements. In this case, we recommend opening the furnace lid during the smelting process.
  • 5. Regularly check the damage of the crucible to avoid damage to the furnace wire.
  • 6. The achievable temperature of the furnace is 1150℃, and smelting is prohibited to exceed this temperature
  • 7. Graphite crucible is mainly suitable for smelting precious metals such as gold, silver and copper.
  • 8. In order to achieve the desired effect, please do not fill the crucible. When there is too much metal in the crucible, the furnace will not be able to provide all the heat required for metal smelting. In addition, steam will be generated during the metal smelting process, and too much metal in the crucible will increase the pressure and even cause harm to the user. In this case, please open the top of the stove.
  • 9. If you need to smelt other metals, please find a suitable crucible by yourself. please remember. Metal smelting will produce steam, always remind yourself to check the working condition and compatibility of the furnace.
