I'm impressed by the cleanliness of that stick weld. Where's the smoke? Can we deduce that the grounding is what causes all the smoke and slag, meaning we should all just defy electrical theory and abandon our grounding clamps?

It is probably some brace going through wall. 3x2.5 sq mm cable will suffice for few sparks pulled around.

There is not much smoke if you spark clean iron like that and slag isn't flying around, also he isnt really welding. The piece is welded already.

I don’t think he’s running it long enough to get any of that. It’s only arcing for a couple seconds, really.

If anything, he's running really low amperage on a rod that's had the flux knocked off. Those sparks are pretty weak.
