Re: homemade plasma cutter

hi,
I've used the 300v power supply. arc starting by the spark gap tesla coil
 

Hi.

My amateur project , but very good working.

Hello devreci,
I have to say one thing, you are very brave doing the circuit on veroboard, especially
since the circuit is so complex.
I have to also say you've done an excellent job. Not only on the PCB, but also the transformer
and the rest of the set up.
Well done!!! :clap:
Regards,
Relayer
 

Thanks.

I am interested in electronics as hobby.

If I work gently, it will be torture, not entertainment.

This device (plasma cut) is very expensive in my country. 3 minimum wage.



I fixed the errors in the circuit drawing.
