    substrate is 6061 and will be using 3/32 4043 filler, and need a 1/4", .250" weld bead.
    thanks guys... we are currently using a syncrowave 350 and the local miller rep is lending us the dynasty for a week to see how we like it.
    thanks
    I do quite a bit of thick alum on my 350's, and here is what we settled on. Ditch the 3/32 4043 and get some of Maxal's new 4943 in 1/8" if you can. It wets like no tomarrow.


    Argon 75%/Helium 25%(less helium with smaller sections down to no helium)
    1/8"/5/32"/3/16" filler rod Diameter depending on position
    1/8" diameter E3 or Rare Earth blend, or 2% lanthanated tungsten(don't ball back and let end glaze over on it's own)
    Gas lense with #8 cup, and 20 to 23 cfh gas flow
    Soft Square Wave(default)
    EN 350
    EP 320 to 350(less EP lessens the average and weakens the arc)
    Balance 70(Raise the balance to control balling back of tungsten)
    Freq. 100(120 constricts the arc a bit much for me)


    You have 8 AC program stations, so don't hesitate to create new programs and test them against each other.

    Have fun!

      man, thanks so much for the info.
      we are pretty much stuck with the 4043 filler, since its a government job and thats what they want and what we certified to.
      im hoping when miller drops the dynasty off, that they have some variety of collets and cups. if not, i will probably spend some of my own money and get what you suggested, thats how bad i want to try the dynasty out.
      again, thanks for your time

      • Dynsaty 350 EN/EP settings.

        I am a new member and have a question about the EN/EP settings on the Dynasty 350. I went through welding school a couple of years ago, but don't have a lot of experience with AC tig. I work at a manufacturer of aluminum petroleum tankers and now have to take a test to be Department of Transportation certified. The test consists of a butt-joint, vertical up, both sides. The material is .194 aluminum 5056, with 1/8th 4043 filler rod. I was running practice plates, with great penetration. Then someone changed the EN/EP settings. We recently phased out all of the Synchrowaves and PrecisionTigs, so no one is familiar with the advance settings of the Dynasty. Can anyone give me a good starting point for this weld on this material?

          There's a lot more to setting up a 350 than simply tweaking the EN/EP--
          --if one's goal is to become competent in setup; let alone in AL tig welding.

          This link: http://www.millerwelds.com/pdf/DynastyQuickRef.pdf
          will help-for very basic reference info.

          The owner's manual, section 5, 'operation' deserves time and study.
          I've printed off 31 pages of it to help me in setting up the menu.
          The more time and effort you expend in learning the setup menus and effects
          of changes, the quicker you'll get up to speed.

          Why?? not just state some specific parameters--that you've asked for??
          -a new AL tigger just really may not be able to use settings that an experienced tigger does
          -Old tranny tig machines and old style inverters have very limited options
          on arc tailoring. The 350 has an unlimited range---especially in AC.
          Experienced AL tiggers know what they're looking for as they tailor the arc.
          Low time AL tiggers-don't.

          http://www.millerwelds.com/resources...uminum-Welding

          Excerpted from my post in the link above:
          ****The most critical part your effort will be the operator, which often is not understood or acknowledged by management. As a 6 month old, new user (but not-new tigger) of the 350, I soon realized that everything I 'Knew' about setting up and running previous high power AC/DC inverters, squarewave trannies and conventional trannies--
          ---meant nothing when learning how to setup the 350. Using old set up techniques didn't produce the same arc
          characteristics. I was able to get 'okay' results, right off-first arc.....and then start the learning curve of the little details of 350 setups....just like every experienced user of the 350 has had to do.

          (I didn't demo. the machine-first, which I normally always do--knowing from other user experiences and Miller's sheets, what it would and could do. Pay first-test drive, later.)

          The 200 cannot independently adjust EN and EP amps in AC, while the 350 can. On heavy AL, this is a significant feature, which isn't recognized by many.

          On thin AL, I don't think it matters as much, especially if one's pulsing in AC with high peak amps.

          The 350 setup parameters are infinite--which is a real hoot and I'm thoroughly pleased and impressed with this machine. It continues to impress me, every day.

          It takes time, practice and study of the Miller setup details in 30 pages of the owner's manual to be able to navigate the menus, sub menus, sub-sub menus and sub-sub-sub menus of the 350's panel.
          There's a bunch of ways to setup a 350 and get satisfactory results---some better than others.
          [The Miller tutorials are good for beginners, but very rudimentary.]
          An operator who has significant experience--knows what they're looking for in the arc and then proceeds to fiddle with the setup to get the desired arc characteristics-that they want.
          The 350 is not a machine for learning 'how to weld'.

          • Dynasty 350 EN/EP settings

            Dave, Thanks for the advice. I'll try to download an owners manual from Miller. Being a factory, our company just put the new Dynastys on the floor. No one I know of ever saw the owner's manuals. I know enough about aluminum tigging to know when something is wrong-just don't know how to fix it on this machine. As you said, the adjustments are endless!

              ...also download this as mentioned prior--this cheat sheet really helps to remind one--where they want to go!

              • Dynasty 350 EN/EP settings.

                Thanks Dave. I have the quick reference guide. Got one with my 200DX. I'll go through the 350 owners manual and see what I can figure out. I was trying to take a short cut to save time. The company gets a little tweaked about us playing with the new machines on their time. Lol ! Have to figure things out after work, or before I clock in. But, I'll get there.

I love my 300, just not sure if the 200 has the guts to bump weld anodized pipe. Seems like the amps would need to be run at max, and the duty cycle limited to 20%.

                  • AC pulse

                    On my Dynasty 200dx I have a provision for pulse which I use all the time, I am wonderig if there is anything in the works for a sine wave or AC type of pulse?

                    The dc pulse when set low enough to work really well drives my eyes nuts with the instant on off......

                    I use the dc pulse at about 50 cycles for the above reason, and I also use the foot pedal in a rhythmic fashion to give me a sort of an AC or sine wave type pulse at about .5 cycles per second, this works really well on 22 gage sheet metal and at the slow rate it doesnt bother my eyes.

                    22 gage steel
                    approximately 10 amps dc average
                    wp9 torch at 8-10 cfh 100% argon

                    I have about 350 hours on my machine and never a hiccup except for the gas valve which I re-lubed and it works fine again.

                    • 350 Memory

                      Hi Guys,
                      I have been using my 3 week old dynasty(sweet machine)almost every day and have a problem with saving setups in the memory,if i setup the paramerters in say #2 and set the EN/EP for "same" and add all the other settings and then add another program in #3 and set EN/EP for independant and add all other settings and then go back to #2 saved program the EN/EP that was set to "same" is now changed to independent but all other settings remained the same,hope that made sense....is there something i'm supposed to do like a save button or something,i'm sure it is something i'm doing wrong.Any ideas? Thanks for your time,Dean

                        • on my 350 you enter the advanced tig settings to adjust wave form by pressing the Amp button and Gas/Dig button together. once in there you can adjust all advanced settings including wave form.

                              • I've read through this entire thread and it seems to be a good idea to centralize a place where process related info can be gathered on a particular machine. I notice no activity in some time now. This is a really good resource especially for a newbie like me. I documented this by cutting and pasting them into one file. I focused on the post that mentioned specific process and the settings used. Good 200DX quick settings reference resource!!! After experimenting with my 200DX, I have a question:


                                1. What is the difference between these two settings:

                                1. Amp 60, PPS 300, Peak 50, Background 50
                                2. Amp 34, PPS 300, Peak 90, background 50

                                if I understand correctly, I realize in #1 peak=30amps, background =15amps, and #2 peak=30amps (give or take .01 or so) background = 15 amps. If the numbers are equal the same amps output will the weld characteric (performance) be the same -- minus the use of a foot pedal? Please let me know and correct me if I'm misunderstanding.

                                2nd question -- what usually causes an EWG tungsten to ball up when welding mild steel?
