: * new and high quality * Made of high quality materials, sturdy and * Working voltage: DC 24-36V * Working current: 20A * Power tube: IRFP260N(50 to 200V) * Size: 100*100*85mm * Spiral copper tube size: inner diameter 40mm, height 45mm * color: red * Material: copper clad laminate+metal It was found that the input current of the new 30*30 graphite crucible is 25A when the 36V power supply is fully inserted. Discover molten aluminum power supply requirements: 24V 350W- 500W power supply(15A to 20A)[Melting point: 660 degrees Celsius] Found to melt copper, gold and silver, power requirements: 36V 700W- 900W power supply(20A to 25A), respectively[melting point: 1083 degrees Celsius, 1065 degrees Celsius, 962 degrees Celsius Usage: DIY small parts steel quenching, annealing metal smelting below the melting point of 1100 degrees Celsius, DIY small cooking utensils, etc. Note: Only steel materials can be heated directly(magnets can absorb materials). Gold, silver, copper, and aluminum cannot be heated directly. They need to be smelted with graphite crucibles. Working for vortex brass heating requires a large amount of circulating water for cooling. It is possible to cool without water circulation. However, it will burn into black eddy current brass and has little effect. Package Included: 1 x induction heating plate with fan 1 x spiral copper tube 1 x 2m water pipe Note: 1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2.Please allow slight manual measurement deviation for the data.
