1. 100% Brand New.
2. Found with a 36V power supply completely into the new 30 * 30 graphite crucible input current of 25A.
3. Found molten aluminum Power Requirements: 24V 350W - 500W power supply (15A to 20A) [melting point: 660 Degrees Celsius].
4. Found melting copper, gold, silver, power requirements: 36V 700W - 900W power supply (20A to 25A), respectively [melting point: 1083 Degrees Celsius, 1065 Degrees Celsius, 962 Degrees Celsius.
5. Uses: DIY small parts made of steel hardening, annealing below the melting point of 1100 Degrees Celsius metal smelting, DIY small cooker and so on.
6. Notice :Only direct heating a steel material ( the magnet can be adsorbed material) Gold, silver, copper, aluminum can not be directly heated, need to match the graphite crucible melting,Work whirlpol brass heating will need to use a lot of water circulation cooling,Without water circulating cooling are possible, but will burn into a black vorex brass, it will not be much affected.
