Man!!!
I was just thinking that you left the argon connected to cut with the plasma. lol....
An O/A powered plasma???? Well, since you didn't understand me and I didn't understand you, I guess we are both party to some new urban legend that we just created.
I've heard of water injected plasma cutters...but...I guess anything could be done if you wanted to do it...lol...
It just goes to show how two people can think they are talking about the same thing and totally miss what the other is saying....my fault on this one.
