    Looks nice. how thick is the metal and how many amps are you running at.

      I think they are 3/16 maybe 1/4

      balance 60
      freq 150hz
      dynasty set at 250A

      4043 3/32 filler

      I could have gotten better welding but did not have anything to wipe the metal down with so just buffed it and welded it.

        Gary:
        Pretty nice, I have been using Isopropyl Alcohol and recently tried Acetone which I like better. Keep up the fine work.

          Not a bad looking job Gary, your consistency looks to be pretty good, I would perhaps try and contract the freeze lines a little more.

          One general observation I have made is that a great deal of the aluminium TIG that is posted seems to be done with 4000 series filler? I know the silicon content of the alloy gives the weld greater fluidity, but I would be concerned about grain boundaries when welding 5000 series alloy. Most of the sheet that I have ever seen is 5000 series whilst the extrusion is 6000 series.
