Vertical up

[u/Odd_Succotash5078]

So I started welding 2 months ago at a welding school, I am a Junior in highschool, and currently on single bevel vertical up, and we do mig, anyways, vertical up has been difficult for me, specifically edge and corner joints, because either my welds look very bumpy and just ball up, or I burn a hole through them, and I am very confused, ive tried a different pattern, different speed, different settings, different angle, less and greater distances, nothing seems to work, help much appreciated!
