        Thanks for the recognition, vary glad to have had a part in helping.

        I went through the same issues. I have used both cerated and lanthanted(sp??) I end up prefering the lanthanated(sp).
        It "feels" like it holds up better.

        any thoughts about this???

          With our 350 Dynasty here with exactly the same problem we still haven't found a solution. We've tried all the different electrode types, had a new HF board fitted and it's still doing it.
          Sometimes when it's doing it, if you touch the filler wire to the work surface and pull it away the arc will light off but it won't do it all the time and you end up with the world's most expensive scratch start Tig machine.
          In the new year we will be insisting on the LWS to supply us with another Dynasty 350 so we can at least compare the 2 and see if it's an inherent problem with the Dynasty 350's.

            I"m sure you will let us know as soon as you figure out how to get it fixed!
            Hope it's not something with all of them!!!!!!!!!!!

              I have been reading this board for several years and the HF problems on the 200DX and been mentioned many times. At one time Miller even admitted there was a run of 200dx's that had defective HF boards. However I wonder if there was more to it than bad boards, maybe more like poor design? What make me think this is the new Blue Lightning HF starting system that Miller just introduced for the Dynasty 200 series machines.

              Like any manufacturer they eventually update their product and call it an improvment while it might really be a correcting a defect. Since I am involved in the maintenance field I have worked with 10 to 20 pieces of identical equipment from the same manufacturer I have some insight. If there is a design flaw it repeats it self over and over. Before long I am repairing the same problems day after day as each piece of equipment fails. The ONE difference here in my experience with manufacturers is that Miller will step up to the plate and take care of their customers when problems occur.

                I found that the arc wandered when I used ceriated tungsten. I checked with Miller's "ask the expert" and they said that this was because ceriated tungsten was prone to axial splitting of the tungsten. They suggested only sharpening the tungsten 50% of the diameter. I didn't like this suggestion because I usually prefer a sharper tungsten with a 1/64 " flat to get good penetration. Since that time I have used the diamond ground tri mix tungsten and have never had the arc wandering problem. I have never used the lanthanated tungsten but many on this web use it and swear by it.

                  As far as that run of bad 200dx's??? Is there a list of serial numbers that shows which ones were possibly bad????

                    There aren't any service memos on the 200DX, therefore no bad run of them as far as the files go other than a better shoulder strap.
