Gas welding thinwall steel tubing is challenging...fortunately once you learn how, you never forget (just like falling off a unicycle!)

I took a couple welding classes at the local community college back when, and patiently learned the techniques to weld thin steel with a torch. Then I got a MIG welder and never did it again...until last week when I had to fix the steer tube (top of the fork) on an old bike, and I decided to gas weld it, and it worked just fine.
