Welcome to the joys and tribulations of aircraft construction.
At least you are welding to a square tube and don't have to fish-mouth
the joints. (Count your blessings!).
I've always done this kind of welding with a torch instead of stick.
It's easier (for me anyway)
But you figured it out already. Do it in sections, and when you start
a new section melt into the existing weld.
At the end of the day you will find muscles complaining that you
haven't heard from before...
