Mig welder questions

I have a used Clarke MIG 130EN, which is a Forney brand welder, made in Italy - it's as good as any 110V welder I have seen. This is a weld from it with 75-25 argon/co2 and some 0.030 Lincoln mig wire:

I also have no formal training btw. For anything 1/8 or less, it works well.
