  • Dynasty 200DX, reduced cleaning

    Hi Guys, Ive been a part of this forum for a few years now, every time I have a Question, its about my Dynastys....

    I have 2 dynastys. One that I talked about here 6 months ago not welding aluminum. No matter what, it would not weld AL at all... 1200$ later, and a circuit board replacement, its fixed. That welder stays in my race trailer, and goes all over the country with our race team, so it has to be in tip top shape.

    My shop Dynasty recently started not welding aluminum very well, but it still welds, just very dirty, and some cases, its not pretty if there is ANY contamination, at all....

    Well, I fired up the second dynasty in the trailer today, and low and behold, welds like it should.

    Im going to attach a pic of the same filler, SAME settings, SAME GAS, and same welder (me ) but 2 different machines.

    If this one needs a 1200$ board replacment, Im NOT going to be a happy camper. Its JUST out of warranty....

    Ive got a syncrowave 250 thats 15 years old almost, and that thing never asks for a board replacement, or good cleaning, or the right settings, you just weld with it, and it asks for more.

    God Im frustraited!

    Obviously, the one on the left is the working machine, tha one on the right is my, apparently, faulty machine....

      Were you using the same gas source,also what about the same torch? Could be bad gas; or a leak in your shielding gas system.

        What are the settings you're using on them?

        AC balance, etc?

          Hey stranger... Sure looks like there's no cleansing side of the AC wave.. After all your problems I'm trying to get as much welding out of the way so if the board goes like yours, atleast its under warranty.

            If he's using pure argon, there's got to be at least some cleaning....otherwise he'd be on DC-...which doesn't weld good on aluminum with argon. But I think you and I are both on the right track here. I suspect that the weld on the right has less cleaning, due to the balance being set differently.

              hey all,

              agreed, the virtual lack of an etched zone suggests that the balance is wrong but,...

              that takes care of most of the usual suspects

              what about torches?- have you tried the bad machine with the torch from the good one? i know it's a long shot but if you have a leak/blocked gas line,...

              having said that, does it weld fine in DC? that would eliminate the gas leak theory- welded any stainless with it recently?

                +1 to that. Try both machines hooked up to the same gas, and use the same gas leads try the same torch on each machine, and make sure that the balance is set exact on each machine and not to much EN(somewhere between 60-70% EN). Good luck man. Let us know what happens.

                  Settings are 65 EN and 140 freq. on both machines. I have not tried different torches, yet.

                  I tried all 3 bottles of pure argon I have here, 1.5% Lan, 2% thoriated, different filler, my neighbors filler, my dogs filler, acetone, 15CFH-50CFH, and nothing made a difference, until I drug out the machine that was tucked away.

                  I have not welded any DC stuff lately, Ill run some beads tomorrow on DC. When the board went in the last one, it welded great in DC.....just couldnt run a bead in AC for the life of me, and Ive been welding since I was 9. This one, however, will run a bead, but its got NO cleaning, and very dirty welds.

                  Will there be a lack of cleaning given poor gas, or impure argon/ect?

                  Thanks for the replies, If I cant get it solved, Im going to send it to the local store that did the first board. I moved from Indy, so my local shop ( Sutton-Garton in indy) is no longer local for the shop machine.

                    Before you dump it over to the service center I would recommend a call to tech support and I would do it on Monday. If the Machine is just out of warrantee, and the issue you had before,(and being a Motorsports) I am sure that they will work with you. Service is Millers middle name, I hope you get the problem worked out.

                      I have a lot of fabrication to do today ( Sunday, lol) so Im going to use the good welder. I have parts that need to go on the car and guys sitting around waiting for them.

                      When I get a spare chance, Ill swap everything over and see what I can dig up. The last time this machine was used on AC, it welded great. Last night I was trying to figure out the last piece of AL I welded, and that was a 1/4" thick 6061 computer case, and it did just fine. Beautiful actually...

                      Here is a pic of the race car- 2006 C6 Z06, 500 hp, 2800 pounds, and a lot of down force. Check out www.world-challenge.com for the series and schedule info





                      Chassis pic- started with a C5 corvette frame ( Steel vs Alum chassis on the C6Z) for safety and ease of rollcage implimentation. We have built 9 chassis' since 2004, all with the dynasty and Syncrowave




                      Thanks

                        Back about 1990 or so, I had a Trailblazer that had a bad bearing plate at the end of the armature (bearing was spinning in the hole), two months out of warranty, Miller paid for the repair

                        That car and frame look beautiful, nice work. Nice to see somebody occasionally that's actually involved in "motorsports" on this board . . .

                          Little update- Welder is doing much better, everything is fine- I swapped bottles from one that I had at home ( different source) and everything seems to be OK.

                          I will swap back to the other bottles and see if it still welds bad.

                          If it does not weld bad, it would lead me to believe that it is something that might be going wrong internally..... Intermittantly.

                          I will update as the day progresses.

                          Thanks again

                              hopefully it is just bad Argon, that always ticks me off but at least it isn't the welder failing.
