  • Two different types of flux core wire???

    I have looked high and low and find all sorts of info that is somewhat conflicting.

    I left airgas the other day with a roll of flux core. To be honest I never even looked at the numbers.

    Its E71T-GS ---- Most of what I can find says that it is a single pass wire well suited for galvanized material as well as thin material. I read the G is for general and the S is for single pass.

    The wire I have used in the past is.

    NR211 ---- This one says its a multi pass (up to 3 passes) or 1/2"


    Can anyone enlighten me on the differences between these two wires.
    So far I can say from experience is that the GS does run very nice on the thin stuff and it also did a nice job on a 1/4 to 1/4 lap joint galvanized. The slag is almost non existent with the GS.

    I switched to the NR211 and found it is a little tougher to run the thin stuff and keep the porosity out. Cranked up it will burn deep, leaving a great looking bead, and having slag almost 1/2 as thick as whats on 7018.


    I know it sounds like I have it figured out but for future use I would like to only buy one type and my LWS does not carry the NR211.

      NR211 is Lincolns version of spec E71T-11, no doubt with some of their own magic added. I've used other T-11's I like better, but that's just opinion based on performance not actual weld bead characteristics.

      Give this tutorial a go.

      The definition of T-GS and a LWS's description of their store brand sometimes don't seem quite the same due to the incentive for marketeers to play with the wording a bit. The descriptions for the T-G and T-GS are way back at 7.7.13 & 7.7.14

        Thanks Sandy,

        It appears that the esab spec is the same as most of what I have found. Stating that it is a single pass wire.

        I realize that every wire is going to run different, I am just trying to figure out the advantages of what seems to be two common wires.

        What would be the advantage to using a single pass wire over a multi pass?

          I'm not positive but as always I imagine price and profit margin are the driving factors. Seems like the GS is what the LWS is always trying to push off on unsuspecting shoppers. "Tastes just like T-11" is what they'll tell you if you ask. I'm not much of a price shopper myself. I decide what I prefer then go on a hunt for it. I did end up with two 8" rolls of GS awhile back just due to a communication error between me and my lil woman. I've about got the last of it burned up. I really prefer the T-11 myself. I don't want to have to worry about single/multi pass issues. I just want to point, squeeze and get with it.
