Hello dear Surasak!
And thank you very much for news about this forum! It`s a thing what about I was dreaming!
About black colour:
As every time, I think that in more region of our work arc sysem is most useful.
Black colour you can make with Ti cathodes and with CO2 gas! It`s so easy:-) I was training it 2 years ago. It takes wonderful black!!!
take a pressure of gas as 4*10 -3 Pa.
As I think in your big mashine it will take a 4 minutes with curent of all sourses near 80 A.
P.S. Surasak, Mail me have you an ICQ?
Big regards!
Serge.
