First Welding Attempt - Suggestions?

Can anyone provide some feedback on this attempt at MIG welding? Apologies, they're just a few short attempts and not the best shot. Material is 1/8" mild steel, Welder is a Forney MP 140 set to MIG, voltage at 5 and wire speed at 6 with .030" wire and 75/25 gas mix. I didn't do any cleanup post-weld here

It’s not horrible. You’re just moving pretty quick imo. Running lines on flat steel with always give you a taller weld making it look funny.

Thanks - I'll try again moving slower this time!

Try making some small 90° joints to practive with too, they give you a nice straight surface to weld against and will be easier to see the weld puddle build up

Nice to see what the 140 MP can do with gas. I got one recently, but I’ve only used it for FCAW so far. Lots of spatter!

One upgrade I did that I recommend is get a better ground clamp. The one it comes with is pretty weak, IMO.
