Just saw this on YouTube:
and was wondering if there are any cheaper solutions for induction brazing. Seems like it would be pretty useful not just for copper pipe, but also for brazing wire used in high heat environments, like an oven. Looks like there are a few variants out there for this type of tool, but it's mostly a niche (read: expensive) item. Seems like it shouldn't be too difficult to make something like that so I wonder if any Chinese knockoffs are sold anywhere. Anyone ever run into a tool like that?
Or maybe resistance heating with something like this:
I imagine it wouldn't be too difficult to convert a stick welder to send the current through two jaws of a "vice grip" electrically insulated from one another, kind of like a spot welder, and then just applying the brazing rod to the red-hot copper. I doubt a stick welder can ever provide enough power to spot weld steel, but maybe it can get enough power to braze (considerably lower temperature) copper.
Anyway, after doing some research, I was wondering if this:

in a basic welder would work. I would just touch the copper with the end of the rod and hopefully heat it up enough to melt a brazing rod on the copper.
