5. Setup

1. Unpacking: Carefully remove all components from the packaging. Inspect for any shipping damage.
2. Placement: Place the furnace on a stable, level, heat-resistant, and non-combustible surface. Ensure adequate clearance around the unit for ventilation.
3. Crucible Installation: Place the desired graphite crucible into the furnace chamber. Ensure it sits properly at the bottom.
4. Power Connection: Connect the power cable to the furnace and then to a grounded electrical outlet. Ensure the power switch is in the "OFF" position before connecting.

6. Operating Instructions

1. Prepare Material: Place the metal to be melted into the graphite crucible. Do not fill the crucible more than 80% of its capacity.
2. Close Lid: Carefully close the furnace lid.
3. Power On: Flip the main power switch to the "ON" position. The LED display will illuminate.
4. Set Temperature:
   • The display shows the current temperature and the set temperature.
   • Use the "U" (Up) and "D" (Down) buttons to adjust the target melting temperature. The maximum temperature is 1150℃ (2102℉).
   • Press the "P" (Program) button to confirm the set temperature.
5. Start Heating: The furnace will begin heating automatically to the set temperature. The display will show the current temperature rising.
6. Monitor Melting: Once the target temperature is reached, the furnace will maintain it. Monitor the melting process. Melting typically takes about 45 minutes for metals with a melting point below 1100℃.
7. Pouring Molten Metal:
   • Once the metal is fully molten, turn off the furnace by flipping the main power switch to "OFF".
   • Wearing protective gloves, carefully use the crucible tongs to lift the crucible out of the furnace.
   • Slowly and steadily pour the molten metal into a pre-heated ingot mold or desired casting form.
8. Cool Down: Place the empty crucible back into the furnace or on a heat-resistant surface to cool. Allow the furnace to cool completely before handling or storing.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your melting furnace.

• Cleaning: Ensure the furnace is completely cool and unplugged before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use abrasive cleaners or solvents.
• Crucible Care: Graphite crucibles are consumables. Inspect them for cracks or damage before each use. Replace damaged crucibles immediately. Avoid dropping or impacting crucibles.
• Storage: Store the furnace in a dry, dust-free environment when not in use.
• Inspection: Periodically check the power cable for any signs of damage. If damaged, discontinue use and contact customer support.
