    Best structural .035 or .045 flux core wire.

    Im looking to run a more structural wire in my miller 211 for a repair on a tractor loader arm. As I understand innershield 211 is not the best wire for this type of repair. The thickest metal in this repair is 3/8 but the arm itself is 3/16.

    The issue that I am running into is that it looks like many of the more structural flux core wires are larger diameter than .045.

    I may just sell the machine and buy an xmt 304 to run with my ln25 but i really like having the 211 as a backup machine, I bought it new.

    If there is a .035 wire that would be ideal because as it stands i would have to buy rollers, liner, and tips to run .045 in this machine anyway.

    I don't believe there is, especially in a self shielded flux-core. If you have a cylinder and flowmeter, you could use .035 solid MIG wire.

    Well at the moment I am working outside so flux core really makes my life easier. I dont have the volts to run dual shield with this machine or else thats what i would do and set up some barriers. I was under the impression that flux core is not really a downgrade from mig welding with solid wire if you disregard the visual differences.

    NR211 is a general purpose wire and doesn't require any impact test requirements and isn't for dynamic loads. Solid Wire is essentially a low hydrogen process and does meet impact requirements and is for dynamic loads. Technically for structural short circuiting circuit isn't allowed but for a loader frame it would be fine if you ran it hot enough and got good fusion. Being outside is a problem though unless you can put something up to block any wind.

    Are large diameter 7018's an option, a 200 amp cc mathine will run a 5/16 rod, and wont loose out much in the depisition rate to a 211 Mig

    5/16" I think you'd need over 400 amps if you could even find a 5/16" rod. 3/32" 7018 would work fine for a 3/16" loader arm.

    nr-232 or 233 are both lincoln structural flux cored wires. i wanna say you could get them in .045

    211 isn't terrible. its not recognized i guess, but.

    how much equipment is held together with 6011? thats what i compare 211 to. take it or leave it, will likely hold, just with a little bit of bashing from anybody who has had to work to "code"

    given what you mentioned you got to work w/, i'd go w/ nr211, and preheat, multi pass if needed. .you might be surprised how far you can crank the heat and feed up on .035 if you look at a chart. nr211 was used for structural probabaly more than you think 20+ years ago, so i wouldn't exactly feel guilty using it. ideally i'd favor 7018 over any wire for tractor arms. the smallest structural t-8 innershield wire i've been able to find is 1/16 dia., which might be a lil on the heavy side for 3/16 loader arm repair

    Sorry! 5/32!! I work in the metric system, so trying to convert to inch fractions sometimes fizzles my brain, im talking 4mm rods

    Re: Best structural .035 or .045 flux core wire.

    Before the Northridge earthquake in California, and all the wire manufactures put thickness limits on their wire. I have no idea how many 1-inch side bend tests I passed with Hobartís 21-B.

    I think it was last summer I found a roll of .068ď NR-211 in the top of my Dadís barn. I took this wire off a job in the early 1980s. I ran a V-butt test with it. Reason I did this, over the years several welding inspectors told me they never seen any body pass a bend test with NR-211. Mine passed.

    I did some fillet weld break tests. Lincolnís Mig wire L-56 took 29-blows from a 4-pound hammer. I beat the top plate down on top of the bottom plate, then had to beat it back the other direction to break it off.

    Far as T-8 wires go, Iíd say Lincolnís NR-233, and ESABs Coreshield 8 are the most user friendly.

    For your welder, I think that Hobart Fabshield 21B or Lincoln NR-212 are about the best wires out there. They are not "code" wires but are better than NR-211, which is limited to 5/16" maximum thickness. I have never seen T-8 wires smaller than .062" so I don't think they are an option for your machine.

    If you see yourself doing more jobs like this in the future, the XMT304 sounds like a very good choice. You will have the ability to run larger Innershield and dual-shield wires as well as stick. You will need an Innershield gun for the larger Innershield wires, however.

    Yeah the icing on the cake is that I have been collecting what i need for a more powerful inverter setup, just havent finished the hunt for a xmt yet. I have an ln25 with the k126 flux core gun .063 drive knurled drive roller, and about 300 feet of 02 welding lead i bought at auction for cheap.


    To be honest considering the amount of time its going to take me to do this project i will probably find one before i finish the fabrication. I have to split the tractor in half inorder to plate the arm correctly so its going to take a while.

    I was going to ask about the 212, it is rated up to 3/4 it says.

    This XMT has been on the market for a while now (the ad has been published several times, with the price dropping each time): http://atlanta.craigslist.org/atl/tls/5169363325.html

    I'd wager he'll take a fair amount less for it, and it's been for sale so long, he'll probably ship it.

    I ran this NR-212 weld on a CC only engine drive.
    The NR-211 was ran with my V350-Pro on CV.

    I'd guess that as long as you stick with the T-11 wires that's as close as you're gonna get to a small dia, flux cored, self shielded, structural wire . From time to time some of the T-G and even T-GS wires from manufacturers claim to be the same as such n such, but, the thing is they aren't required to be so there fore can't necessarily be relied on from one time to the next. That's the this is "chocolate , this "tastes" like chocolate thing marketing comes up with.

    I run a bit of and prefer the Hobart .045 T-11.

    i agree with wdave but don't recall having cracking problems with the 211 ever. even 1/8" 7018 would do nicely.

    NR211 is really designed for dynamic loading. 6010/6011 are. There's thousands of miles of pipelines welded with 6010, NR211 not so much. LoL The fact the original loader arm cracked tells me you want to do a good repair so it doesn't crack again. I'd do it with stick if it was mine. Probably a 6010 for full pen followed by 7018 cap.

    I have a couple of welders certs that date back to the mid 80s that are D1.1 3G unlimited certs that were run with NR-211 on CV machines back in the day. that And NS-3M. theres alot of structural steel out there welded with NS-3M thats no longer Seismic but still holding just fine
