    Thanks Joe,
    I understand the procedure, and your post is helpful. I am concerned with what the benefits are etc. I guess the best way to find out is to experiment and see what happens, I am using 500 cycles and 50 percent peak and 20 percent background. It does make the tungsten point last longer as the low current (14amps) would be better suited to the .020 tungsten but that is so fragile I really dont like using it.
    I am going to experiment with a much higher current and less percentage on the peak and maintain the same average and see what it looks like. penetration isnt critical on this particular weld but it does need to look nice.
    I am thinking that my main problems are eyesight and hand control, both of which could be cured by shaving 40 years off my age ha!!
    It is a nice machine though, I tried stick the other day and it worked fine too.

      Question about Miller Dynasty 350 setup

      Hey to all from a new member,

      On the 14 pin Amphenol connector, which 2 (lettered) contacts would I use to hook up a remote momentary contact switch for 2T hold mode?

      Can I access the arc voltage for use with an automatic torch positioner? Can I get the voltage minus the starting high frequency?

      Thanks very much,

      David

      Edit: I found the answers on page 31 of the Dynasty 350 PDF.

        Hi all
        Is it possible to upgrade "old style" 200DX to the new Blue Lightning arc starts? My DX was purchased new in 07.
        Thats the one issue i have had is that it does, on occasion, have erratic starts, other than that, an amazing machine.
        Thanks

          I do not believe that it is possible. This is due to the software and hardware differences on your machine.
          If I am wrong about that, you will soon hear different I am sure....... pg

            You are absolutely right. I recieved a very speedy reply from Miller about this, and they said the same thing.
            Don't you hate it when stuff becomes obsolete so quick? I was thinking of selling the Dynasty as i have a new (to me) Syncrowave 250, but i might as well keep it, as i won't get much for the "old style".

              My understanding of the subject goes like this.....
              Sometime around July 2008 the change was made.
              Nothing to designate the change other than before or after a certain serial number you either had the update or you did not.
              You cannot update the earlier version machine.

              I had just bought a new Dynasty off Ebay in July 2009 and read of the change here on the forum.
              The break point serial number was given, so I went to check my serial number.
              Although my machine was a 2009 model, the serial number was a lot earlier than the break point number.{ Like 2007.**

              Long story made short, that prompted me to call Miller and see what was the deal. They had no record of my serial number at all.
              It turns out my Dynasty had been stolen and the serial number on it was for a 2007 Millermatic 350 machine.
              I later discovered my machine is a 2009 model by the labels inside and has all the updates except....... I have no warranty because the serial number is not original.

              Just be happy yours is not a stolen machine. The differences are not that great....... pg

                I saw your post re. the serial number issue. Thats must have been a sinking feeling when you realized what was happening
                Oh well, for what its worth, nothing ever seems to happen when stuff is on warranty anyways, its always a day or two after the warrant expires
                One thing i do to mitigate erratic starts is i have increased my postflows on both AC and DC, I found it made quite a difference in arcstarts.

                  You'd be surprised what that obsolete machine will bring.

                    Average amps

                    I was thinking it would be nice to have some way to monitor average amps when you are dealing with the pulse settings. I know it can be done by doing the math, but for a quick adjustment, some way to monitor it would be very nice.
                    I usually change the settings, then strike an arc, full pedal, and watch the amp meter to get the average reading, it would be nice to be able to read the average amps with the helmet down or when making the adjustments...

                    I made a few welds using about 2 cps pulse 50 percent 20 percent background, it makes a beautiful weld on the turntable but drives my eyes batty, it makes it look like some of the machine welds I have seen.
                    It seems that the pulse rate needs to be 50 cps or so to not bother my eyes.

                    I think I have too much free time again maybe??

                          Vin-man Welding,

                          Sorry for the delay in responding to your question. Yes, the Dynasty 200 SD has hidden menus that are the same as the DX model. Everything should be the same between the two models with the exception of the Pulse and Sequence features (which are not included on the SD).

                          Please let me know if you have additional questions. Thank you

                            Just finished an aluminum sign support for a restaurant.

                            It is a V shape with 2 pieces of 3/*" thick alum plate welded to a 6" x 6" x 1/2" square alum tube.

                            Settings for my Dynasty 350 are as follows:

                            AC frequency - 200 Hz

                            Waveform - Advanced square wave

                            Amperage 275
                            EN - whatever the Dynasty calculated - sorry I didn't think to check until I was done. I can recheck the values.
                            EP - whatever the Dynasty calculated

                            Balance - 70%

                            Tungsten - 1/8" pointed 2% thorium - all I have in 1/8"

                            Tig wire - 3/32" 4043 alloy.

                            The job went well even though my beads are sloppy.

                            I did make sure to clean and clean the metals and this saved me from lots of cussing.

                            One effect I noticed was that the arc seemed to be very "forceful" for want of a better term. By this I mean that there was a dimple in the center of my arc puddle and the alum seemed to be repelled from the tungsten at the tip.

                            I got a 1/2" thick piece of scrap and just ran a bead with no filler and had the same effect. I even tried pushing the tungsten into the puddle to see if I could get the tungsten to touch the alum but the puddle just parted like Moses and the water.
                            Have never seen this effect before but again I haven't done a lot of alum.
                            Also tried same settings at 100 and 60 Hz with similar results.

                            So is this normal or am I doing something wrong.?

                              I have noticed this too on high current settings, I dont have a clue why it does it either, but I dont do much aluminum welding either. I dont seem to have the problem with thinner material.

                                Are their ways to improve the starts on an old 200DX?
