Includes a tested 53 V power supply for reliable operation. - Moderate power for small parts and DIY projects, suitable for heat treatments such as hardening, annealing, glow work, and other heat-related tasks. Can also be used with a graphite crucible to melt metals like gold, silver, copper, aluminium, and more. - Induction heating section driven by a low voltage DC supply (12-48 V). Maximum current 20 A, maximum power 1000 W. - This circuit is an inverter-based system, not a conventional induction heater by itself; the copper tube feeds into a high-frequency transformer for efficient power conversion. It features a tailor-made cooling substrate 8.5 mm thick to provide high cooling performance. - Practical use scenarios: - Jewelry making and small parts heat treatment such as hardening and annealing. - Melting metals in a graphite crucible (gold, silver, copper, aluminium). - DIY metalworking tasks requiring fast, localized heating for components, fasteners, or small assemblies.
