Another rate my first weld thread (MAG)

[adomik]

Hi guys. It's my first time trying to weld with MAG. These are beads that I made after about half an hour practice. The welder is an Esab Origo Mig C280 Pro, shielding gas is CO2 and material is 3mm mild steel sheet. The first two photos is the same piece of metal and the third photo is a plate on which I've laid my very first beads and tested various settings that day so it's only for the reference. On the fourth photo rate only the butt weld as I know that the other ones are just plain horrible.
Please rate my welds and give some advice on what to improve

Clean the metal to bright and shiny. Flap disk/grinding wheel.

Will get much better results.

Noticed that too. I had thought that it isn't that important for practice but later realized that the initial struggle was probably caused by rusty metal. Surely will pay attention to cleaning metal thorougly the next time.

What motion are you using? In school they taught us to do a cursive e/l and that came out pretty good. I remember that I wasn't moving the wire around enough when I was doing the motion, I felt like I was really making it wide when I wasn't.
