Function: 1. The heating plate is made of high-quality PCB, 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 use large heat sink and large power supply, provide better heat dissipation effect. 4. The output terminal uses three M4 copper columns in parallel, which can be connected to other outputs such as the high voltage package. 5. The use of 6 IRFP260 and 12 parallel resonant capacitors, high power, high efficiency. 6. It can be used for DIY hardening, annealing and other small parts heat treatment. It can also be used with a graphite crucible to smelt gold, silver, copper, aluminum and other metals. It can heat up evenly and quickly, which is very convenient.
