Does your helmet have dials to adjust the darkness? I hate them (auto darkening) myself, and went old school with interchangable plates of slightly less shade (cringe worthy to some) i cut a 1/4” slot to see through at the top, no battery lag when they get weak, no batterys, last time i used auto darkening i kept getting flashed because of the battery being low and i cannot justify the replacement battery cost despite semi regular use. As you begin to watch the puddle form just keep it “wet” on both pieces at the same time as best you can, it took me a long time to develop my “welders wobble”, just keep practicing, possibly watch some videos on welding sheet metal (car panels) the power feed of wire machines can cause funny things to happen, to slow gets an inconsistant bead and to fast puts the wire through the puddle causing blow out and possibly ruining (especially thin) work pieces. Ive used mine to fill largeholes in pipe and on my motor cycle seat as it had a hole.
Positively not the worst welds ive seen, my high school fab class was largely ungifted in welding and some never got it, that just meant more time at the machine for me “helping”.
Ps the 10 lbs spool is the way to go, so much waste in the 1-2lbs spools.
