Hi everyone, I am new to this website and would like to coimment on the use for the first time of the E3 (purple band electrode) I noticed that it last longer and it maintains a more stable arch. I am just learning TIG and if anyone would like to share techniques or share lessons learned about TIG,would be appreciated to help me become proficient with the skill. thanks in advace!

Hello, I have been tig welding for about 2 years now and I use tig everyday for my work. I have learned a lot from doing variety jobs such as, different lenses and how they change the efficiency of the gas flow to the best way to sharpen your tungsten. But mostly the more seat time you get the better you’ll become. There is a lot to learn so keep your eyes and ears open to learn new ways.

hello jim. lenny here, from D.K. heard you got this site going. congratulations. got a question for you. miller will be letting us borrow a dynasty 350 this wednesday for a week. i will be trying it out on that thick aluminum job we always do. substrate is 6061, 5/8″ thick to 3/16″ thick, all T joints, requiring a 1/4 thick bead. can you suggest some starting parameters to get me started, since i have never set one of these machines up before ? settings such as frequency, EP and EN settings, etc, and will it be beneficial to continue… Read more »

hi lenny, i work on the dynasty and have read thru the manual. when you first turn on the machine in factory settings, whatever you put as amps everything else will be the same. so i suggest you push the amps up to 300 to start with then you can place the En to 350 and the EP to 175. what this does is set up a ratio for you. when you change the amps the ration will stay about the same. this ratio will help the tungsten ball up less and make it last longer. then you can lower… Read more »

rebecca,
thanks for the tips on the dynasty. i am gathering all the info i can and this will help a lot.
thanks again

Lenny, glad to see you on here. How did you get miller to loan you a dynasty? Anyway, like Rebeca said, keep the machine’s amp at 300. This can be confusing because you need to make sure that you are in the main amperage mode and not another. So, I will take you through some steps here and yes you should consult the manual as you are messing with it. I will try to keep this simple: 1. Set the first column to A/C 2. The rest of the columns, except the last one, leave as they are. 3. This… Read more »

thanks for the info jim, cant tell you how much i appreciate it. i am researching and gathering as much info as i can, but knowing what you suggest will get me going right off the bat and welding is gonna help, since i really wont have time to play with it, needing to keep the production going. the miller rep, JC, was in the shop a couple weeks ago with our airgas rep and he said he would loan the dynasty to me for a week once it was in the neighborhood, which is wednesday. our current contract will… Read more »

jim.
yes, the post time mark has to be fast, since i was sleeping at 8:53pm last night. lol.
i will ask JC for the savings chart, but feel free to e-mail it to me, in case he dont have it. no rush at all, im dreaming of the dynasty but will only maybe get one if we actually get another contract on that job.
i have always used the argon helium mix, 75/25% on this thick aluminum. and use argon-co2 for GMAW mig…. correct me if im wrong…
thanks again jim, much appreciated.

Yes you are correct for the gas you are using. I didn’t read what you said correctly. I just saw the 75/25 and figured you were talking about the co2 version. Must have been the time delay. Anyway, what I will say about the dynasty is that you could weld thicker aluminum with just 100% Argon, which is not recommended with the conventional machines (syncrowave). Since you already have that helium mix, just use it like you have already been doing. Remember, this dynasty is an inverter and it excels in producing very small beads to working with the thick… Read more »

hello jim..and rebeca. after a few day welding on the dynasty, i think i got it close to where i need to be. on the 5/8″ thick aluminum, i like the settings at: advanced wave, EPEN the same, (seems to have a more fluid puddle), 120hz, 100% argon and 75% balance. did some thin aluminum testing also and could lay a .125″ bead at 400hz.. couldnt mess with it too much since i had to keep the production line moving, but for now i like the machine. but, after welding the thick aluminum, i would have thought i would be… Read more »

hello again jim… i was just looking through my Maxall “guide for aluminum welding” book that JC gave me when he dropped off the dynasty on wednesday, and i see in the book they say, ” the 6xxx series base metals have 30% higher thermal conductivity than the 5xxx series base metals, making it more difficult to produce consistent quality welds in the 6xxx base metals”. can you explain this any further ? i do know from welding on the thick 6061 parts we do, that one day i can weld pretty darn good looks beads, and the next it… Read more »

Guest

Lenny, I know exactly what you are talking about and let me briefly describe in my opinion, what could be happening. First off, 6061 is not made the same way that the 5000 series is manufactured. It is brought to its desired properties through precipitation or tempers. That is why you will usually see a “T6” on the material specification. 6061 aluminum is designed to be at its hardest after it has went through this heat treatment. The 5000 series is also heat treated but by a different process that makes the material not able to reach its desired properties… Read more »

wow jim, thanks for the detailed info on the 6xxx series aluminum…
every time i get info such as this, i print it out and keep it in a folder for future reference.
i wish i would have gotten into the welding field a lot sooner in life, but with help from people such as yourself, its making me a better welder each and every day.
thanks a ton jim, and talk to you later….
yes, JC did give me a worksheet comparing the dynasty to the syncrowave..

well jim, i wrapped up the dynasty later today, and JC is picking it up monday morning. im gonna miss it im sure.
wanted to thank you again for your help man. its much appreciated.
talk to you soon. have you heard of any AWS meetings coming up soon ?

hello jim,
just wanted to share a few pics of our parts we are welding at work.
the aluminum parts are 6061 base, 5/8″ to 3/8″ thick using 4043 filler and a syncrowave 350 with 75/25% argon helium, and the steel parts are 4130 chromoly tubing welded to 1018 steel plate using 80sd-2 filler. we are near the end of this current contract of 3000 parts each over the past 18 months.
take care and thanks for all your help over the years jim.

Thanks Lenny, the welds look great, especially since your always under so much pressure to get them done. If only you could relax in welding class again..Keep sending pics.

hello jim, hows it going ? here are some pics of some locating fixtures i was contracted to make in my part time venture of welding and fabricating after my full time job, right here at my home in my back yard shop. and i will be welding 50 of these aluminum powder coating gun weldments each month, along with other work coming from the same guy really soon. i hope this will really be a money maker for me since we all could use some extra cash. would love to branch out on my own one day, but at… Read more »

hello jim, got a question for you.
i might be getting a side job repairing and strengthening a go kart frame that’s made out of chromoly and was wondering what tig filler to use ?
thanks, hope all is well,
lenny

james
Guest

Lenny, I just saw this and that is why i’m late to respond. You should use an 80,000 tensile filler metal to use with chrome moly if you will be tig welding it. You could use the regular ER70s-3 or 6 if you need to.
