Understanding cleaning action of AC reverse polarity

If you get a thick piece of copper and hold the AC arc on it you can actually see the ions dancing off the copper plate. I suspect it has to do with the conductivity of copper but it could be the dark color lets you see it better. It is really quite amazing to watch. After I grind my tungsten I light up on a 1/4" hunk on copper and starting noticing the arc looked very big on AC when I did this. When I really looked at it I noticed I could literally see the ion cloud of cleaning action etching the copper. Try it you will be amazed. The longer the arc the more you can see it. Enjoy


Sal, thanks for the post

here is a video I shot on AC balance
