Why doesn't NR-212 come in .035?

Imma guess because it can weld up to 3/4" Plate.

So if you were welding, say, 1/4" plate, there wouldn't be any difference between 212 and 211?

Re: Why doesn't NR-212 come in .035?
Imma guess not for multipass welding?
Well.that aint the answer. Says for single or multipass.

I would think the same.

Re: Why doesn't NR-212 come in .035?
Might not be able to get enough flux in the wire in .035" size or maybe there's not enough demand for it in .035".

That kinda ties into why I was asking. NR-211 .035 is supposed to be good for up to 5/16" regardless of number of passes. .045 is really too big for thinner stuff. If I wanted to weld 1/8" metal with .035 wire, I'd HAVE to use NR-211 because NR212 doesn't come that size.

Well, Dave.... if they don't make it, there won't be much demand for it...................

For welding 1/8th inch NR211 should be fine, the problem with E71T-11 (NR211) and E71T-G (NR212) is excessive aluminium in the weld from heavy welds, for a smaller weld it's not a problem as most of the aluminium ends up in the slag, but larger the run the more ends up in the weld metal making it brittle and it builds up weather you do one larger run or run multiple passes, 211 has more aluminium in it than 212 which is why 212 is rated for thicker material, it's also why NR232 and NR233 don't have a thickness limitation, it's got about a third of the aluminium content of the -11 or -G wire.

Gotta agree there, I wish they made NR232 and 233 in .045, but since no other manufactures seem to make a -8 wire in anything smaller than 1/16th i'm guessing there is a production limitation as to why that is rather then it just being a demand thing, I think in Lincolns case it's not that though, almost everyone makes a -11 wire in .035 and .045, and NR212 isn't actually special, only lincoln makes a -G wire, and it looks to be almost identical to almost all other -11 wires, Hobarts -11 (Fabshield 21B) is rated for 3/4 material in all diameters (.030 -5/64th) despite not being -G rated like 212.
So I think for lincoln them not making N212 in .035 is to make sure they don't cannibalise sales because I don't think there's anything special about it.

Interesting answer, thanks. So what's the purpose of the aluminum in NR211/212?

I'm going to guess it's a deoxidizer, and probably explains why heavy 211 welds are a b!tch to cut out with OA.

Re: Why doesn't NR-212 come in .035?
You will find the smaller size wire has fewer types.
I use E71T-11 0.030" for my welding.

Somebody must stand on 2 stacked chair with a tiny funnel pour the flux into the wire.

Yes and the guy with the mortar and pestle wore out his shoulder grinding the flux small enough to fit in the wire.

Re: Why doesn't NR-212 come in .035?
I think aluminum is added to give higher deposition rates but could be a deoxidizer too. E70-T4 has more aluminum in it and is a high production wire. It's the wire that caused Lincoln to put seismic rating on specific wires.
