Dynasty DX set-up for aluminum

admin

I been welding aluminum with my Dynasty DX.. I have learned today 1st i'm useing the wrong tungsten. I will have to order some 1.5% Lanthanated tungsten.I use Argon because i weld both steel & aluminum, My welds on steel are great! but aluminum could be better they sometimes look as you sprinkled sand on top of them.I need help with where the AC freg & AC Bal% should be set? And gas gauge setting?Thanks for any help
Reply:Your best bet is to browse the miller website (www.millerwelds.com) they have articles specific to operating the Dynasty and taking advantage of its features.My 2 cents...stay with Argon gas at around 25 to 30 CFH...go with ceriated or zirconiated tungsten (I run zircon myself) Your AC freq will adjust your arc cone, wide and narrow, play with it, and your balance controls the duration of your pos and neg cycle, more positive equals more cleaning action and less heat into the work, more negative equals less cleaning action and more heat into the work.  Generally I run 60 to 70 percent into the negative cycle for most work on clean ALU.  The best advice I give to most apprentices when they are learning tig is to get yourself comfortable BEFORE you start to weld, keep your arc length tight, and use your pedal.  Tig is a wonderful process giving complete control over just about everything...learn to use it and learn the machine...the beauty welds will come in time.

Reply:Yes sir i need a turn table.. I think turning down the Bal to 60 will help me a lot less cleaning.
Reply:If you are using 4043 with the advanced squarewave setting on the dynasty then you will generally get some "sand". But the consensous seems be to that the advanced squarewave stirs the puddle up too much. There are two ways I have found to fix it, if you have a newer dynasty with the 4 different wave forms you can go to a new modfied square wave (or what ever they call it) or you can use 5356 filler. I can put down beutiful welds all day with the 5356 but can't get the 4043 to come out nice and smooth. -DanOwnerDW Metalworks LLCMiller Trailblazer 302Miller 8RC FeederMiller Passport PlusMiller Dynasty 200 DX W/Coolmate 1Hobart Handler 135Hypertherm PowerMAX 30Smith O/A Torch SetPlus much much more

Reply:Thanks for all info!! should i go buy 5356 rod.How do you set-up for Cast aluminum about 1/4 thick?
Reply:I doubt the sandy apperance is from the rod itself, how do you clean your material and filler?Have we all gone mad?
