Old thread, but thought I’d add this here…there’s a new video from weld.com on YT and one of the sponsors is http://cantesco.net/en/project/plasma-arc-water-table-fluid/
The video is here: https://youtu.be/4hjBJMUBCiE
Thought I’d put that out there, as I’ve not seen this product mentioned (sorry if I missed mentions). I have not used it, but I’ve been looking for something and was going the DIY route, but may check this out…
