Product Description body { font-family: Arial, sans-serif; line-height: 1.6; margin: 20px; } h2 { color: #c00; } ul { padding-left: 20px; } Specifications Working Voltage: DC 24-36V Working Current: 20A Power Tube: Original IRFP260N (50A 200V) Size: 100x100x85 mm Spiral Copper Pipe Size: Inside Diameter 40 mm, Height 45 mm Color: Red Material: CCL + Metal Features 100% Brand New. Compatible with a 36V power supply for optimal performance, allowing for a 30x30 graphite crucible with an input current of 25A. Required power for melting aluminum: 24V, 350W - 500W (15A - 20A). The melting point is 660°C. Required power for melting copper, gold, and silver: 36V, 700W - 900W (20A - 25A). Melting points: Copper - 1083°C, Gold - 1065°C, Silver - 962°C. Ideal for DIY projects such as steel hardening and annealing below the melting point of 1100°C, and creating a small cooker. Note: Directly heats steel materials (magnetically absorbable); for gold, silver, copper, and aluminum, a graphite crucible is needed. Brass heating requires substantial water circulation for cooling. Package Includes 1× Induction Heating Board with Fan 1× Spiral Copper Pipe 1× 2m Water Pipe
