Sheet support for a plasma machine?

You can use angle if you want, but remember it's sacrificial so you want it to be relatively easy to replace.

I'm sure they're generally attached to the frame, as there should be enough contact. I know when I use my plasma, I can get away with working on top of a sheet of metal with the clamp attached, and don't have any issues.

Could you clarify that a bit, are you saying your table is a sheet of metal that is connected to plasma ground or something else?

one of my reasons for angle would be that they are self supporting so I would only need a few for small work and can be moved about easily, will look into strips too.

I only use my plasma manually, but have at times just clamped the earth to whatever sheet I've just cut the end of, then recut bits on top of that sheet. I've never had any issues with it not starting, but then mine has a high frequency/pilot arc start, so may be more tolerant of a less than ideal ground.
