Every single panel sold at my home depot does not include a ground bar

What size wire do you have on that 40amp breaker? It looks like UF-B.

Make sure you use Noalox on your aluminum wire connections.

10/2 for my welder plug. They didn't have size 10 NM on a spool and I didn't need 20 ft coil. Manual said 12 but robert on the cautious side I just bumped it up. And yes I have noalox. I just got a neutral lug from HD. Not siemens but the hsquare D one works after I ground down the side of the ground bar channel a bit

10/2 is only good for 30amps and should not be on a 40amp breaker.
Please do not post advice for stuff you don't understand. This is a welder circuit. For many welders the #10 cable could be on a 50A breaker. All this is safe and code compliant.

Thanks for the info.
I'm not too familiar with welder circuits so I had to educate myself. I just saw this thread. https://www.garagejournal.com/forum/showthread.php?t=443929
Is the plug on a welder unique so the receptacle can only be used on welders?
Thanks again.

It would be a bit cleaner if you backed the ground wires out of the bars so only a short amount sticks past the bar.
No jumper required.
No-alox not required unless wire manufacturer calls for it.
Not the case for a welder circuit.
nope. there are no special plugs or receptacles for welders.

I don't recall ever seeing a 6-50 on anything other than a welder and the only other welders that come with anything else are 15 120v. There was a time back in the day they came with a 10-50 but that has long since passed and a couple Centurys I saw might have come 20A 120V but they are rare and havnt seen one in decades.
If a guy puts a plug on another tool its up to him to verify the circuit is adequate, that the recept is proper. In the case of motors there would be HP rating limit that would insure the safety of the wire so to speak.
FWIW,,, the limit is 12 wire on a 50 breaker.

Alright everything's in except the breaker on the main (I'll wait for that as I will be doing multiple things in the panel at the same time).
I used the anti-ox stuff on the wire. Wasn't crazy hard to put in, but I tried to fish the wire through an angle out the other side of the wall and it was tough to get into a 90 so I scrapped that idea.
Thanks for all the help!!

Did you unbond the neutral bar?
I scrubbed the wire and brushed the noalox in there with the wire brush. I didn't goop any into the screw for the terminal. I see one work where it's thick in there and others where it's just normal. thoughts? One thing I saw was that our aluminum these days is good enough to not even use it...but I still will. Cheap insurance.
So I ran into a problem. My alum wire is too thick for my main panels terminal bars. I'll have to get those add on terminals but those will **** up two screw holes each. Is it kosher to add multiple ground wires in a single screw hole? I will need to free up 4 holes so four will need to be doubled. I figured it's ground so it shouldn't matter. I mean all there terminals are mixed neutral and ground anyways

you can put 2 ground wires per hole.
make sure neutrals each have their own hole.

OK I wired everything up this past weekend. I ended up having to relocate the neutrals and grounds like I mentioned (one neutral per hole don't worry). One thing I ran into...the 2 gauge stuff was so thick I decided to use the last 4 holes for them (each terminal adapter takes up two holes). This involved moving one of the ground wires from the grounding rods. Well...it was a PITA to remove and I couldn't get it into another hole, so I ended up splitting it to a 2/4 wire split into two different holes. That struggle alone took me like 30 minutes. But everything's hooked up, no sparks flew, all is well. Thanks for all the helpful insight and now I have a much better understanding of the NEC and tips from everyone!

Did you split up the strands of any neutrals? If so that needs to be fixed.
No they were all Romex. Also I made the assumption that due to the nature of a ground only that can safely be split up. I wouldn't mess with the other lines
