Description Function: 1. The heating plate is made of high quality PCB, has stable performance. 2. The power line is fully covered with copper cover, which can increase the generation of electricity and heat. 3. This product uses a large heater and a large power supply, provides a 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 packet. 5. Using 6 IRFP260 and 12 parallel resonance capacitors, high power, high efficiency. 6. It can be used by DIY players for hardening, annealing, and other heat treatment of small parts. It can also be used with graphite crucible to smelt gold, silver, copper, aluminum and other metals. It can heat up evenly and quickly, which is very convenient.
