A 3kg electric melting furnace for melting and casting metals including gold, silver, copper, aluminium, lead, tin, zinc and sterling silver. The furnace combines a high-temperature ceramic melting chamber, graphite crucible and digital PID temperature control.
Key Features
- Maximum Temperature: Up to 1150°C.
- 3kg Graphite Crucible: High-purity graphite with good thermal conductivity and a pouring groove for easier transfer of molten metal.
- PID Temperature Control: Digital control system with a K-type thermocouple monitors the furnace temperature for accurate operation.
- Insulated Design: High-temperature-resistant ceramic chamber and insulated lid help retain heat during melting.
- Applications: Suitable for workshop and metal-casting applications involving gold, silver, copper and other compatible metals.
Important Safety & Operating Information
- Read the instruction booklet supplied with the furnace before use.
- Do not exceed 70% of the maximum crucible capacity.
- Before use, preheat the machine and crucible to 300–500°C for 3–5 minutes to help prolong crucible life.
- The maximum continuous working time is 3 hours. After 3 hours, switch the machine off and allow it to cool for a minimum of 3 hours.
- Do not move the furnace until it has cooled completely. Allow approximately 3–5 hours for cooling.
- Do not place a hot graphite crucible directly onto a cold metal surface, as rapid cooling can cause cracking.
- Cracks may develop in the inner ceramic chamber due to normal temperature fluctuations and do not necessarily affect operation.
- Typical heating and melting time is approximately 48–60 minutes.
