  • Lanthanated Tungsten

    Just curious... what's the difference between 1.5% Lanthanated (Gold) and 2% Lanthanated (Blue)

    If you use Lanthanated, which do you prefer and why?

    <smart a$$ on> A tungsten supplier/distributor doesn't know the difference in 1.5% and 2% Lanthanated product? Well, I am just guessing here but maybe......................a half a percent. <smart a$$ off>

      I was told on an earlier post that blue is for heavier aluminum and steel, gold is for thinner.
      I went to buy some and my supplier doesnt stock it so I need to order it.

        The higher percentage gives you a bit more current capacity. So, for 150A-200A, I like using a 2% lanth. 3/32 tungsten.

          I will take a shot at this, seems to me I read somewhere that the rare earth is distributed evenly in the tungsten (hopefully) and during an arc condition travels to the arc. As the lathium is consumed the amount available is reduced and can in theory be depleted to the point where the tungsten would act as a pure tungsten. Of course in practice that would mean that lanthium in the tungsten would need to last (arc on) and have enough to be effective until the tungsten is consumed and have some extra to be safe. So if I remembered all that correctly it would mean that since there is more lanthium in 2% than there is in 1.5%, it seems to me that the 2% would function correctly longer. I have used 1.5% & 2% lanthanated and cannot tell the difference (I use only 2% as it is easier to keep only one type) and because I tend to dip more often than I should I don't think I would ever keep one going long enough to deplete either the 1.5% or the 2%. Anyway that is what I remember, if I am wrong I welcome all corrections.

            i also use the 2%, i did not see a hole lot of diferance in the arc starts but the 1.5 is said to start a little easyer but the 2% defenetly holds up to the heat better. i can run a bead with the 2% and the tung looks like i never started the arc, wile the 1.5 tends to ball at the tip a bit. the 2% stayed a nice sharp point with a small flat on it even after a good 3"'s of 150A AC on aluminum. it also kept its point when used on DC. all in all i realy liked it on both aC and DC better than any of the others i tride, the cerated came in a close 2nd but it balled up fast, both lanthanated and cerated worked really well on DC, cerated has a tendency to spLit on AC, and has a shorter oxidation life than the lanthanated, so i figured it was best to stick with the 2% lanthanated as it worked out realy well on every thing meaning i can stock just 1 type and have every thing coverd.
            i'm using it on a TA-185

            the 1.5% lanthanated didnt become a big ball it just kinda balled the verry tip where i had made the flat for AC. it still welded nice though.

              Its been my understanding that the 1.5 is best for low amps and the 2 for higher amps. Right now I just have 1.5 1/16" tung. becouse so far my work is all on thin material. I plan to get so 2% in the 3/32" at some point. I have not tryed it yet though.
              I have managed to run the 1.5 % out of juice so to speak. It started acting very strange and the tip looked good, I resharpened and every thing straightened out. Most generally I end up dipping it though.
              To all who contribute to this board.
              My sincere thanks , Pete.

                thanks for the math lesson... I guess you know now that I am blond...
                actually everyone else answered my question pretty well. Thanks guys. I ask because I see everyone talking about using "2% Ceriated or Lanthanated " and I assumed it was 2% Lanthanated...

                well now Weldcraft (a member of the ITW family same as Miller) is selling tungsten, but it seems they are only selling 1.5% Lanthanated (gold) ... and of course 2% Ceriated, pure, thoriated... and their new "Rare Earth" (gray) which apparently has been run through the Miller test lab and performs really well... and all this got me to wondering if there really is a need for both 1.5% Lanthanated AND 2% Lanthanated?

                anyway, thanks for your comments. I learn a lot from you all, and am very appreciative.

                  FWIW if you sharpen the 2% to a sharper point it also works well in low amps. i also have some in 1/16" and it works realy well also.
                  most all of the try mixes get good reviews but tend to be a bit higher priced.

                    That gray is the same as, if not the same, as Diamond Grounds tri-mix I would bet. I really didn't care for it, but some swear by it.

                      I don't think there is any standard for gray band. I think it's refered to as Specialty Mix or something to that effect. ( At least in the Miller Tig Handbook. ) I guess that means whatever the tugsten producer cooks up draws from the die is what you get.

                        yep the home brew or try mix they whip up get the grey although in europe its standerd for 2% cerated. just incase you happen to be there on vacation and need a stick or too.

                          Some shops have gone to rare earth because of the radiation given off while sharpening is supposed to be lesss than the others Ive used both and they seem to be all pretty close

                            diamond ground has a realy good book on tungsten, might be werth dropping them a e-mail to send you one out, it breaks down all the tungstens and what they were designed for as well as ther good and bad traits.
                            cerated was the first non-radioactive alternative to thoriated
                            cerated was designed for DC only and as it has the highest migration rate of oxides. this limits its life span but in low amps it should outlast thoriated
                            lots of info in there book.

                              RE the Weldcraft "Rare Earth" tungsten... I don't know anyone who has switched yet. I'd be interested to hear any reports on performance from out in the field, and not just the Miller test lab...

                              Yes, I think it is similar to the Diamond Ground Tri-Mix, or Multi-Strike from Europe and what we sell as ArcTime... in that the G classification is in fact not standardized, and the manufacturers don't divulge exactly what's in it as it is a "trade secret" like McDonald's special sauce :-)
