    Angry Snail Trails and Porosity

    All right welders, I am not new to this game. But for the life of me I need to know where all the "snail trails" and occasional but sometimes frequent porosity comes from in dual shield FLUX CORE wire?

    I looked at lack of shielding gas: Nope. 25 cfh
    I looked at wind or air currents: Nope. Inside the shop and no fans.
    I looked at the wire: Nope. Same stuff I've been using.. ESAB 710x.
    I looked at the material. Nope. Even ground off the mill scale.

    I was welding sched. 40 3" pipe to 1/4" flat bar using .045 710x wire at 25.5v and 380 IPM.
    Maybe a couple of you more learned folks can TS this for my old A__!

    Glad to see you back...

    thought you were in the Keys...

    Might be a bad roll of wire....

    thought that I had heard ESAB was now marketing Chinese wire....

    I never go below 40-45 cfh even inside. Don't push dual shield if you can help it, drag it.
    Approx. 3/4" stick out.
    Has the wire been in high humidity for a while? Just some things I've had problems with in the past.

    Had a new opportunity in the Carolinas. Working Marina needed a private welding contractor. Been at it now about a year. Building mostly Anodized aluminum stuff but, like most of us, doing whatever it takes to keep the wolves at bay.
    Really nice to hear from you too!

    Cool

    I weld .045 ESAB 710X everyday. Turn your volts to 23.3 and the wire to 233 and try it. You are too hot for the part...Bob

    OK. I'll give it a try. As for the CFH... am I using enough at 25? I know my other 350P machine is set for AL only and I run 45 cfh on the 100 Argon. But I can't ever remember running more than 25 cfh on the 75/25 gas.

    I run 25 cfh with 75/25 on my machine. Also i use the M-25 Miller gun and when that rubber O Ring at the end of the nozzle wears out i get holes. Don't know what gun you have but just a thought...Bob

    The new mm350p came with the Bernard Q gun. I believe it's to 300 version.
    What's frustrating about it is that the other day I ran 30+ pounds of this 710x wire on a bunch of 1/2" plate projects all in one day using the same settings and had very few issues except for the occasional puff of Mother Natures breath in the shop. Today however, I was just shy of giving it a blue letter cussing.

    Are you using the same cylinder as the previous day ? Some have complained about random bad fills.

    I have found that when you are over running the wire this happens. To hot, to fast or both. Try turning it down some. Gas should be fine.
