Function: 1. The heating plate is made of PCB grade, it has stable performance. 2. The power line is completely covered with a copper sheath which can increase electricity and heat production. 3. This product uses a large radiator and a large power supply, ensures better heat dissipation effect. 4. The output terminal uses three M4 copper columns in parallel, which can be connected to other outputs, such as a high-voltage package. 5. Using 6 IRFP260 and 12 parallel resonant capacitors, high power, high efficiency. 6. It can be used by DIYers for hardening, annealing and other heat treatment of small parts. It can also be used with a graphite crucible to smelt gold, silver, copper, aluminum and other metals. It can heat evenly and quickly, which is very convenient.
