Description
The induction heating circuit uses 18-50V low-voltage DC power supply, maximum input current 20A, maximum power 1200W in short time and long working power 500-800W. It can be used for DIY players to quench and annealing small parts. It can also be used with graphite crucible to melt gold, silver, copper, aluminium, lead, tin and other metals. The circuit can directly heat iron, carbon steel, graphite and other magnetic materials, but the spiral spring can not be heated.
