Send me a PM if you don't get the answer you need and I will hook you up with a real person with a real email address.

I agree Floyd, already delete spam in my inbox two to three times a day, random phone calls from people that think I need what they are selling!

What are you looking for on the NR233? I've run a bit of that I believe.

The question was of no great importance. I was just curious.
On the Procedures for NR-233, I noticed that the deposition rate and amperage at their lowest suggestion
was LOWER for the 0.72 than for the 1/16 wire.
Why would that be?

I was looking at different wires to suit my needs, installations of columns and beams in new house construction, mostly.
I have uses NR 211 0.45 and it was OK. I try to pre fab everything in my shop with GMAW. In the field SMAW seems so slow.

I keep hearing about the NR 233 and tried the 0.72. Works pretty good.
But 0.072 seemed a little much ( for my experience level) on the usual 1/4 inch wall tubing.
Any gaps ( my fits don't have gaps, Im talking about fill a connection at the rounded edge of larger tubing, right?) and I start wishing for GMAW and no wind.

I did call and after being handed off a few times talked with someone that pretty much said the 1/16 just ran better at that lowest setting. And the 0.072 ran acceptable at its lowest (recommended) setting.

The Lincoln tech suggested I stick with NR 211 if the seismic qualities are not required. So far we are not prone to earthquakes here in Central Texas.

I have a roll of 0.062 in the suitcase ready for an install later this week.

Oh yea, I wish all those wires came in a 12 lbs rolls. Who wants to lug a suitcase all around with a 25 or 40 lbs roll of wire.
And I would rather put on a fresh roll than have the same 25 lbs roll around for a year or two.

That is odd that it is lower. Must be something to do with amperage/voltage or something...????

The NR211 I have used many times and is comparable to Hobart Fabshield 21b and Esab Coreshield 11. If you're ever in a pinch those run very similar to the NR211 and from what I've learned have about the same properties. I have used a ton of this stuff, probably literally. Seems the Lincoln spattered less, going by the burns on my legs and arms as a comparison.

The NR233 from my experience is similar to Hobart XLR-8 and Esab Coreshield 8. Properties, again, from what I've learned all seem to be fairly similar if I remember correctly. I have not run a lot of the NR233 but have run a bunch of the Hobart XLR-8. When you get that stuff set right it is dreamy! Slag will literally get blown off by the wind and leaves a glass smooth finish. The slag is heavier, much heavier than the NR211 and similar so running horizontal and overhead fillets and horizontals can be tricky. It takes a bit of trigger time to get the hang of it but the deposition rates are phenomenal. Fabshield 21b on the highest all position numbers for 1/16th wire is 3.2lbs per hour. XLR-8, 1/16th, highest all position setting for voltage is 6.3lbs per hour. I use this frequently when out rambling around the country or on bid jobs where I need to get in and get out to maximize profits.

I've used the XLR-8(NR233 equivalent) on 6-8" pipe legs, 1-1-1/2" flanges down to 2 inch solid legs. When we get into thinner stuff I drop down to the Fabshield 21b(NR211) in an .045. Running that bigger wire on a thin wall pipe leg vertical gets a bit spooky.

Filling in with the XLR-8/NR233 on flat fillets is outstanding. I did a sign not to long ago where they added stiffeners(12) all around a 42" pipe leg. The center plate was way undersized we believe because it was sinking in the center. I used the XLR-8. They had everything cut square but where the plate set horizontally there was a 1/4-3/8" gap or better. It worked amazingly well at filling up these.

I can't recall specifics and I usually am running well over 100ft of wire(2/0) with the 1/16th. I connect what I will need as far as lead then play around on some scrap while checking my suitcase meter to obtain the voltage I want. XLR-8 I typically run around 21-22v's and believe 23v's is the highest recommended. Wire feed speeds 190's to 250's provide the best results. On the NR211, 1/16th the voltages are much lower as is the wfs. Mine is typically run around 17-19v's at the suitcase and wfs 75-100 range. Seems every time I hook up it's slightly different than the time before. Some days I refer to it as a fire breathing dragon. Lays in perfect, stacks perfect and you just fly thru. One job I was catching up to the guys hanging steel and I actually had to take a day off for them to get ahead of me. Then I still caught up to them.

I prefer mine set on the higher end of the recommendations, Hobart, Lincoln, Esab and I have run miles and miles and miles of this stuff. 1/16th in my opinion is a great mid range size. The .072 although not much larger I personally have not had a need for. For me it means probably jumping up to 3/0 lead and that means mucho $$$$. Most of the guys I talk to doing what I do run an 045 wire and when I tell them I'm running a 1/16th because it doubles the deposition rate they say, "hmm, we'll have to check into that". Can do a lot with it between the two different types of wires I've mentioned but sometimes you just need to drop down a notch to the .045". I only buy the 33lb spools. Last job I did I went thru 5 of them so a 12lb roll for me would be a nightmare. I have 10lb spools of a Hobart X80 I use for grade 65 material, certain jobs require the 80,000psi wire. The Hobart I didn't much care for so got some triple nickel from Lincoln I have yet to try.

Maybe I answered a question or provided some sort of information,
