In theory that should be easy to weld with wire but--wire being what it is--I'm guessing that most of us who mig weld a fair bit have run into situations where you just can't get it to work right. As you surmise I suspect that the material in the bucket is seriously contaminated. We used to do a lot of "farm" repairs and you could definitely get contamination in the metal from whatever it was exposed to. Even after you had cleaned something up completely you could smell it cooking off when the heat got into the metal.

One thing that hasn't been mentioned is the possibility of bad gas. It's not common but it can happen, usually because the previous user drained the bottle right down and didn't leave a tiny bit of reserve in it. Once this happens you get air in the bottle and if it isn't properly purged before it's refilled the next user is gonna have problems. If you weld much you're occasionally going to get a bottle of gas that is "skunky" and if you don't figure it out it can drive you nuts.

The biggest sign is porosity in the welds. If there is enough contamination the porosity usually shows up as soon as you start with a new bottle but once in a while you'll find one with just enough contamination that the problem can be intermittent--those are the ones that can drive you crazy.

Easiest way to check for a bad bottle is to swap it out for a new one--easy to do if you've got a spare or your supplier is close but not so much if your miles away from another bottle...

Run a pass on scrap piece of the 3/4 plate. If good, it is not the wire or gas that is causing the problem. I would go back to stick too in the meantime to get the job done.

It is something I considered. And it still may have some shit in it.

I grabbed a piece of scrap iron from the new ears and ran some stringers. They seemed fine.
I then did some welding on the bucket and the end result was way better. My shoulder is causing a lot of pain and I did the welding with my left hand. I am like Cutter today typing with one hand. I;ll get some pictures later.

I just got THE CALLI'm going into the hospital on January 24, I'm so happy I could just shit!!

So I better get used to welding with my left arm
Meanwhile back at the ranch I just ran successful test beads on the ear steel, and was going to dredge out one of the old ear plates to try the contaminated side. The I ran out of wire.
Not a problem....and I heaved another roll onto the feeder. Started threading it and went hmm, this can't be .040 wire. Crap. No, it's .030
So I have to learn what happened and get used to thinner wire. It's been on the shelf too long to run crying to the government over it. I spent a while practicing with the new stuff.
I had been running 40 wire at 425 inches and 27 volts and it made a perfect spray weld, so I could do 3 passes. Now I am running 27.5 volts and 700. Gets the same result, perfect sharp wire end and liquid puddle, but a smaller bead.
I practiced this for a bit, and concluded that it will need 4 stringer beads. It started going fairly well, hissing arc with only the occasional snapping sound, and then there was a crap eruption, so I quit for today.
Welding with the left hand inside a 5 inch wide box is never going to be a thing of beauty, and I guess I will have to accept it and I have to believe it will be strong enough. Tomorrow I'll gouge out the bad...again.

Yeah. Tomorrow, they are gonna call me about pre-op stuff at a clinic, blood tests, x-rays, and such. The I go to the local quack for a medical history, and then I am ready.
They did say, because it is a major trauma center, there is a slight possibility I could be bumped, and then get back in at the first available time slot.
So far True Dough has not flown by, and no one has gone postal on him so it should be fine.
