Is that the right thing to be doing? I know the two vertical sides would be enough, but just hoping I am welding the tops correctly. I will grind the top and bottoms flat but want to be sure there is a good joint.
Thanks in advance!
that's probably the easiest place to get a blowout. You'll need to learn to adjust your speed and that will help. Another thing that helps is that you don't have to run a continuous bead... Run a couple of inches, then move to a different area and run a stitch there... Spreading out your stitches and then coming back will help.
Learning your machine's settings will also help.
I wouldn't do multiple beads like you described. Shouldn't hurt, and you're not going to put enough weight on it to really matter, but you should be able to do a single bead for a butt joint (unless it's more than 3/16", then you should start overlapping beads)
Turn down the heat, as you did, and 'wash' your puddle from the solid over onto the butt end... You'll do fine.
