That looks really good. Your technique and heat level look great. Only advice I'd give you is to clean the joint better before welding. There should be zero mil scale on any of the metal that is within a half inch or so of the weld.
I use a wire brush wheel on a bench grinder for the cleaning, then a quick wipe with acetone.
Well thanks! and yes, I was being lazy and didn't clean it too much. lol I wouldn't say my weld is better than yours! I am still trying to be more consistent when it comes to starting and stopping. I just really need to spend more time practicing. I'm sure if I was able to weld every other day it would be a ton better!
