I have a 12 volt automotive battery powered blade welder and it works
like a champ. Does bi-metal and regular carbon steel blades perfectly

There is a link to the manufacturer of the bvlade welder on my website
under my 20 inch home made bandsaw link on the projects page as well
as the modifications to the H/V bandsaw page.

Opinions expressed are those of my wifes,
I had no input whatsoever.
