    Hi, I have been working on some projects with my Lincoln Pro-Core 100 welder. It is the flux core model. I was wanting some opinions from some other welders about the best flux core wire. If you have an opinion please share it.
    thanx.

    I use the home depot 0.35 Flux core wire in my Clark 180 all the time and have never had a problem with it.

    flux core yesss

    fluxcore is great when ur outside in the wind and if you dont have the money to buy gas

    Dave...that link brings me to a fabrication company..not a welding supply.

    pancake hoods

    Thank yall so much I have looked everywhere. How do you like them? They look pretty functional. Thanks again.

    They're out of Fresno, Ca. I buy A LOT from them, they're service is excellent!

    Wendy's also sells an elk skin liner for the eye-piece, makes it a little more comfortable.

    I've got the "flip front" lens, it's a little heavier, so I put plastic lenses in there to lighten it up a bit.

    i always keep a few small roles of flux around for any outside quick fixes. it works realy well in the MM135.
    i welded my 2 story 22'X20' shop togather with it.(see pic's)
    over the 5+ years i have hed it its more than payed for its self.

    Flux-Core wire

    I just use MM-135 w/30 Flux-core wire and miller 35 tip and burn baby burn!!!!

    DDA52 Thanks, James ....at least someone out there gets it
    no problem, i suppose i could have looked it all up like you did but that was a lot of typing .

    it really is a shame you have to go to such extremes to prove such an obvious difference.

    Thanks, James ....at least someone out there gets it.

    Darmik, you just do not get it. Call Lincoln and tell them you want to run a .035 E71T-1 or E71T-9 wire on a 100 amp mig and see what they tell you. You are just not getting it from me or the numbers. Have you ever even run this type wire before? There is a huge difference between a self shielded flux core wire and an externally shielded flux cored or metal cored wire. Yes, they both have a flux core. BUT they are not the same in action or requirements. Not even close.

    For anyone else reading this excercise in futility, a flux core can be either self shielding, or externally shielded. The self shielded wires are what are the most popular for small units. They require low power and will still penetrate well and weld much thicker material than the same sized solid wire. They do not require shielding gas. The flux inside creates its own shielding. If you use gas with a self shielded wire, you wll change its composition and that can be something you don't want to do. They are made to be used without gas. The AWS has a couple of classes for these wires. They are E71T-11 and E71T-GS. There are a few others, but these are the most popular and easiest to find. The brand names and numbers are Lincoln NR211-MP, Hobart Fabshield 21B and Fabshield 23 ...for example. These are general usage wires and have no mechanical properties.

    There are more flux core wires that do have mechanical properties. They are self shielding as well. These would include the AWS classes of E71T-8, E71T-6, E71T7-K2 and others. Lincolns popular ones are NR-232, NR-233, NR-203, NR-305 and NR-311. Hobart has a few as well. They incluse the Fabshield 7018 and Durashield 8-11 wires and others.



    Now, an externally shielded flux core wire is a different animal. It must have a gas to provide shielding. It can be either straight CO2 or an AR/CO2 mix. These wires are used on high output machines due to their higher voltage requirements. They also burn hotter than normal flux core wires. They are not the same as self shielded wires and cannot be run in place of said wires on small machines. The AWS classes thes in several categories. They are E71T-1, E71T-9, and E71T-12. These are the common 70,000 tensile strength designations...there are more. The vast majority are in the .045 and greater size range. There are a few of the .035's around. These have large voltage requirements even though they are a .035 cored wire. Miller weld engineers have said that the MM210 will run .035 dual shield...barely. It requires a setting of 7/80, which is almost max output of a 210a MIG unit. This is directly from Miller. Now, if a Miller 210a MIG will barely run .035 dual shield, according to the engineers that built and designed it, how in the world would a 100a machine be able to run it???????????????????????????????????????????????? ?????????????????????????????????????????????????? ?????????


    Now, I do not profess to know it all and never have. I am getting all of this information from spec sheets on both Lincoln and Hobart wires. They are available online if you care to download them. It is very easy to determine the voltage and amperage requirements from the charts. The values for .035 are clearly listed if you care to do the digging. This is all I am going to say on this. It is a waste of my time to go any further. Those that know anything about this type of wire will know what I am talking about. Those that don't...I invite you to do the research. I'm done.
