Lapidary Arc Welder?

[DocRocz]

Does anyone had any experience with lapidary arc welders?
I'm asking because some of the things I'd like to make seem like that would be a better tool for the job than a torch.
Such as soldering metal when it's right up against stone.

Any and all comments welcome.

Thanks in advance.

I have an older model of this

seldom use it - as I'd rather use a torch,  but it can work OK for quick fixes on settings around stones, BUT the stone still gets hot.

Many years ago I saw a demonstration of a tiny TIG welder which in the right hands  could weld 2 strips of aluminum foil together. It would be perfect for jewelry work. But it wouldn't be a tool for the inexperienced welder, or someone old like me who can't hold their hands steady anymore.

And a foot....it takes lots and lots of practice.
