    What solder would you recommend for this?

    Going to be soldering a joint that needs to flow 80-100A at 12v. Is standard leaded solder good for this?
    Popcorn.

    upload a foto of it.
    any solder will do, but lead-free is stronger.
    i'm more interested in what is connected to what that can handle that current!

        You need to make sure the copper or the conductor is conducting the current and not the solder like always. As long as this is true, regular solder is fine. If you need the solder to matter, then either you're doing it wrong, or what you really need is welding.

            Yeah, speaking of that, it's not "what solder would you recommend for this"... it's "what solder iron would you recommend for this"

            I think you'd need a torch to get anywhere with that much thermal mass to solder.
