    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!

          Check out this thread:http://www.millerwelds.com/education...ead.php?t=1912

          There are a few of my ranting here.

          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.


          Sorry about the Hijak.

          Back to topic about blue tung... Soemtimes eating blueberries give me a blue tung...

            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,

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