    I know that when I get my tungs too hot they go blue/black. if hteir isnt sufficient post flow they will go funny too.

    How long have you had your 200? Mines not working right.
    Will it weld? I loooove electricity!

    Being fairly new to the machine and no prior friggin tiggin' experience, Im not sure what is and isnt correct function BUT I do know what isnt workin properly and stated in the above linked thread.

    Chris, the problem you are seeing can be one or all of three things, first is heat too high, second is improper shielding gas or flow rate and third is tungsten not sharp enough. Dave

    Mine are sometimes like that but i just chalked it up to running to much heat on to small an electrode. Especially on aluminum when really cranking it hard. Didn't seem to hurt welds though. I have the older SW180 at home and it has worked great, lots of time on it with no issues. Doesn't have pulse though.

    Chris,

    What you are seeing is oxidization and contamination of the Tungsten. Try increasing your post flow time. The post flow does two things: in addition to shielding the deposited metal from atmospheric contamination until it "freezes", it also cools the Tungsten down as well as keeps atmospheric air away from it until it too is non-reactive.

    Later,
    Jason

    I wouldn't waste one second of my life worrying about it.
