Yeah, I figured it might be enough to weld it. I modified the rear suspension on my car with it (welded a lower shock mount on an F body setup) that's held up okay. I just have zero training in welding and am pretty much just flying by the seat of my pants. Finding out that the feed was screwing up helped a lot in making cleaner beads, but the flux wire still has a bunch of spatter. Just didn't know how much I wanted to trust myself on a frame rail.
