Thread: Maybe a annealing machine bones?

Benefit of AC is it drops do 0V every cycle so the arc automatically gets suppressed every single. Im hoping a 24V automotive relay will work.

I paid around 110 dollars for a 48v 20amp PSU from aliexpress. As the project mentions this type of PSU will not have quick enough up time to get the induction coil working so need it switch it first. I think all up ill be about $300 nzd including the power supply. A flame one would be cheaper but I like the idea of not having a flame inside the house and I wanted a project to do.

Shooting and other bits and peaces has taken priority. Ill start building mine in the next few months once things are back to normal.

I'm basing mine on an old PC with it's power supply and case. This will give me 12V and 5V supplies for the pump and control circuits and arduino. Will use an RC servo to operate the case release and a 60A solid state relay (got a box of them) to switch the output of the 48V supply. Possibly look at a case feeder too later on.
