Here’s a thing I made the other day, the weld on the left I need more amps due to the thicker seatpost collar, but was pretty happy with the join to the top tube. My welder is an old transformer machine with hf start and post/pre flow but not really any other settings. Still learning and getting better. Been using a no.8 pyrex cup and gas lens off AliExpress, just got a couple of fupa12 cups and a jazzy 10 to try out so will have some fun with that shortly
