This is the above weld close-up. It looks like to me either argon starvation or if not that then argon cooling the weld too much to make it a useful weld.
The weld beads(or balls rather in this case) aren't welded to the base piece at all. I can break them off easily with the screw driver.

If you meant the gas holes on the MIG nozzle holder?
Gimme a minute. I'll take few pictures and upload it.

The gas tap is fully opened on the bottle, and the flow meter knob is fully open as well.

Why are you just waiving the gun around? You aren't going to get anywhere doing that crap.

Pure argon is a pain with mig.
Argoshield has oxygen and carbon dioxide??? In it.
These serve 2 purposes.
One is to create a better arc transition so a smoother weld, but also more heat.
So with pure Argo you'll find you'll always have a rough, tall weld.
I tried playing with argon as I had the bottle with my tig welder..
It's a pita and just but the bullet and got argosheild

Ok just went into the thread more.
First post looks like your trying to weld galv steel..
That'll explain a lot of it.
Throw it in the bin and get some scrap black steel from a workshop.. (if they are decent they'll let you grab some scrap from bins..)
Secondly.
That's a very small mig.
3mm think will be about max material thickness.
And .8 wire max.
.9 will be to big and require to much to weld it.
Ok.
So undo the wire feeder wheel.
Pull the trigger and set your gas flow. Want between 12 and 16 lpm.
You should be able to hear it and feel it on your cheek.

Depending on output and setup it shouldn't matter Westy I have tried all combinations over the last 20 plus years , we only use straight argon at men's shed with no trouble at all , if you had to choose one gas and one gas to cover all applications it would be argon .
Check with Dr google and you'll find it's a common diy gas , if you were only ever going to weld low carbon steel I'd probably go a mix but the cost these days for swap and go is the same .
Dom can do stainless steel with his Tig if needed so it's a better option imo.

Mate Ben is right what are you doing way too fast and erratic with the hand piece , try pushing only and slow down .

Sure it's common but has side affects.
It'll weld, but you won't get smooth welds like argosheild. And with a welder that has 6 settings you need all assistance you can get..
Ok so just watch the vids..
It's still galv. That's what the black is coming from.
Hot dipped galv sheet of that thickness is probably penetrated 100%.
So imo to go forward, go bin that galv stuff.
Also don't just drag it. For setting up just hold it in one spot and pull the trigger..

Last time I tried straight argon with a mate the weld looked darker, even though we could see it getting into the root, the toes looked really cold
Edit
Just looked at the pics. That's what it looked like
2nd edit
You should cut it in half and polish and etch ( if you have any), see what the peno is like
