Hello to all!
I, like all members of this discussion, am trying to build myself an induction annealer for my expensive 6.5x47 Lapua cases.
I purchased a circuit complete with coil on AliExpress.
The circuit is a 1000W ZVS with 6 x 0.33uF capacitors.
Since its coil out to be too large for the cases, I purchased a second coil, of which I attach the link.
The coil is Color C, with 2 series of coils.
The standard coil, with the LCR circuit, measures 1.95uH.
The second coil that I purchased was 1.65uH.
I tried using 12V 50A car relays but these cannot handle the absorption of the ZVS circuit.
At the moment I am not equipped with an instrument that allows me to measure the absorption in Amperes or Watts. If you have any instrument to recommend I will gladly accept the advice.
The machine I would currently like to build would be very simple, I would do the loading of the cases manually.
However, the annealing and unloading of the cartridge case would be automatic.
I would use 2 timed relays connected in cascade and set for this purpose.
As soon as I manage to get the necessary components to make the creation less horrifying I will post some photos.
The material must arrive from China.
Thanks for reading me and sorry for my bad English, it's Google translator's fault
