    While I disagree with this pissing contest, sundownIII is right... Too many newbs answering or trying to answer questions above their head, or asking questions that are something you learn in the very beggining or even on the back of the **** tungsten, or electrode package you buy ( amperage range). Or how about those 30 amp spool guns ehh??? Wink Wink. I dont post here often because usually, it just aggrevates me...

    It is that type of user who I dont think these books should be, or would be intended for. I am no KB fabrications by any means, I think Im a fairly competant weldor and although im only 23, I have been doing it since I was 11. I have invested alot of time and money in machinesand attempting to better my skills and I really would like an advanced in depth book on how to extract the most from my dynasty...

        Put me down for one of these books too.

        I'm also a visual person. Nice color pics in the book would help. If there's a good video or two around, I'd like to see those too.

        I learned how to MIG weld by watching and "listening" to others. When the bacon's frying with an even sizzle and there's not a lot of spitting, you're welder settings are close.

        Now I just need to get myself some of those audible and visual cues to help me with this new TIG welder of mine..

        Thanks Miller!

          Sounds like many of us are of the same mind... a good comprehensive book.. with the whys and wherefores would be great... Miller Dynasty inverters really are the Cadillac of inverter welders (with a price to prove it)... These machines are smarter than I am... and sure would like a textbook to help level the playing field... and to take full advantage of the myriad of features....

            H80N,

            Laughing!

            Just spent most of the afternoon "playing with" the Dynasty 200.

            I had had enough trouble figuring out pulse settings on my Syncrowave 250 with the pulser option. As may know, the Sync goes from .1 to 10 PPS. Now I'm looking at this little Dynasty which goes from .1 to 500 PPS.

            Thanks to Brocolli, the article on H.L. Lyons Company was a tremendous help in getting me "in the ballpark" for some of the work I was doing.

            The owner's manual tells you how to adjust the machine, but neither it nor the Tig Handbook do a very good job of identifying some basic range parameters to start with. With a range that large (.1-500 PPS) that's a lot of tweaking.

            That's just one minor example.

            Thanks for bumping the thread.

              the manuals for both the 200dx and 350dx Dyns.... seem to be written with the assumption that we understand the variables... so they give use the rudiments of how to adjust them.....
              an old Estonian saying translates roughly to...

              "The more you know, the better you know, how little you know...."

              that is where I am,... each time I get a little glimmer more on how to use these..... I can see how much greater the capabilities are...

                Thanks to Brocolli, the article on H.L. Lyons Company was a tremendous help in getting me "in the ballpark" for some of the work I was doing.
                I agree that we need an in depth manual for the inverter machines this information from the H L lyons Co. is very valuable and just the type of information that most of us are talking about. I thought I checked everything and I did not see this article thank you. Now a question has anyone tried these settings on inconel ,718 or 625 or hastloy ect? I know, why don't I just try it myself well I would if I had some inco parts in the shop but I don't right now. Thank you

                  Hi, back when I bought my Dynasty 350 I went one snowy afternoon to Visit with Fay Butler Fabrication. I had already read the Miller student package information from front to back and back to front several times.

                  Also, read some engineering info on Electricity, flow, etc.

                  Anyhow, for those not in the know. Jesse James west coast choppers was one of Fay's many students.

                  Fay was given one of the prototype 350's to run thru the paces and had it about a year before product release. In other words a pretty sharp guy. His unit actually had a tig torch cooler bypass setting.

                  He took me thru the whats and where's and why's of this and that. But even he didn't use all the functions. He said what works, works. Though he did say some of the features like triangle wave forms are great for thin alum.

                  Anyhow, I am up for a book. At this point I understand what frequency does to the the tightness of the arc, and to a lesser point of AC +/-. I find my welds still look a little chewed up from to much cleaning even with 70-90 percent balance on some stuff and then dirty looking welds on others with 50/50.

                  A book would be great, and so would a hands on. Seems up in the East coast MA is usually the last place they (Miller) or anybody else ever have anything good. Now in PA it seems they have stuff going on all the time. And I have to say why not MA.

                    pulse

                    I have been experimenting with the pulse on thin gage material, I was using 500 cycles, 50 percent 28 amps 5 percent background. This setting works good as it keeps the tungsten point much longer on .040 tungsten. The weld looks better but I think its mainly because the point lasts longer. I am using this welding the edge of two .020 pieces

                    I tried a low pulse setting of 20, and with the auto darkening hood it is very uncomfortable as my eyes are trying to change as it pulses.

                    I have tried .020 tungsten but it so fragile I have more or less given up on that.

                    An article explaining this feature I could appreciate thats for sure as well as the other features of my inverter machine!

                        I just finished 30 of these pipes, have another 30 to go, it sure would be nice to know the theory of pulse and what to expect with different settings etc....

                        I do know that the low pulse rates drive my eyes nuts!! I do know its pretty noisy as well, beyond that I am kind of in the dark ha!!

                        A book or an article written on the theory of this would be very nice indeed!

                        I have learned that the pulse frequency varies the output some as well, so setting it up I make the changes then hold down the pedal, strike the arc,and look at the ammeter, then make changes to the amp control to keep the same setting.
                        Varying the AC frequency also changes the output amps somewhat too, I am refering to the Dynasty 200 DX machine

                        It took me a couple of years to get the feel of welding thin gage steel verses stainless, they are similar but have many differences as well.
                        Experience is the best teacher but it is the most expensive and takes the most time.....

                            Interesting discussion,

                            Over on WW there's a discussion going on about using low PPS rates and transformers, and high PPS and the inverters.

                            One thing that thread has pointed out to me is that a lot of people tend to just throw out a bunch of crap (regarding settings) and, I guess, never expect people to try them out or question them.

                            As an example, for the last couple weeks, I've had a couple of rather large SS rail jobs on imported trawlers. Melted about 5# of filler (a lot when you're using .045 and 1/16"). Using the Sync I had settled in on a setting around 50A, 2 PPS, 70% Peak, and 30% Background. Up or down a few amps depending on where I was. One things for sure, SS doesn't like a lot of heat.

                            Then I read the H.L. Lyons thread. Tried out some settings using the Dynasty 200. This is 7/8", .065 wall SS tubing. 52A, 200 PPS, 70% Peak, 30% Background. You wouldn't believe how much better the weld is.

                            Anyway, along comes another poster who's using a transformer with a PPS capable of .01-10 PPS. (The OP who started the thread has an inverter). He recommends a setting of 150A, 30-40% Peak, 2.5 PPS and 20-30 Background. When I questioned him about the 150A he gets all defensive and says that works for him and it's because he's only using 150A 30% of the time.

                            Not satisfied with the answer, I set his recommended settings up on my Sync 250. Started at the end of the tube. Dropped the pedal, and, BAM. 1/4" hole in the base metal. Arc force was so strong it blew base metal all the way to the other side of the tube.

                            Bottom line. Recommended settings were hogwash. 150A is way too much for .065 stainless, I don't care if it is only on for 30% of the time. I've sent him some recommended setting that WILL work with his machine.

                            The whole point in posting this information is that any "recommended" settings should be "validated" by a compentent authority (Miller) before they're published as gospel.

                              I welded .065 wall 304 at 48 amps DC, full penetration. This setting is dependent on the machine of course.
                              On a slow pulse rate, I could see it blowing a hole in it at 150 amps! Even at a high pulse rate and 30 percent background I think it would still be far too hot.
                              Most of the new age dairy welders use the "walking the cup" procedure, it keeps the heat affected area down and makes the weld look nicer as well, I have tried it but its hard to teach an old dog a new trick.
                              I am wondering if the pulse can give the same results??

                              I read the article mentioned and it is very good, I will have to try it out tomorrow.

                                Pop,

                                Give these settings a whirl on the Dynasty. Think you'll like them.

                                Amps 48-52
                                PPS 200
                                Peak 70%
                                Background 30%

                                You won't see the pulsing, but it's there. These settings have worked well for me on the exact material you're working on. You'll need to run pretty fast. Are you backgassing the tubing. If not, you're going to still get a fair amount of sugaring even at those settings.
