Re: Some recent CNC Work
tacking alum without filler? you are a master! i've never been able to get that to work 
i tried welding tubing at 400hz, that sucked *****, went back to 120 and no pulse, everything was gravy.

20 hz, you're funny Rok. 60 out of the wall.
Nice work, very unique.
As for the welding, 500amps seems like overkill, but it should look nice if you move fast enough. I think 300 amps would do fine. I really use the variable polarity amplitude adjustment if I'm over 100amps. You rarely need more than 100 amps of cleaning(especially billet cnc stuff) and you can really save the tungsten. I did a job for the polytechnic, and I did it at 320 amps EN, 120 amps EP, 90% balance, and 400hz. It was 3/4" thick, and 2 ft long. Welded like butter. Anyway, not trying to tell anybody how to weld, just throwing my 2 cents in. Nobody talked much about that, which I think is the best feature once you take the leap past the 200.
I really haven't used the 400hz much except for tacking without filler, or getting into tight spots, as I really like 250hz for my aluminum exhaust. Might have to tinker again. The dynasty 350/700 almost have too many variables...almost!

I've welded massive (1meter x 1 meter x 140mm thick) oil coolers with 1inch solid billet flange fittings that have been preheated with oxy torch and only topped out at 350amps on my synchrowave 350..

Re: Some recent CNC Work
I haven't actually welded it yet so 500 amps is just a guess. I will know within about 5 minutes exactly what settings need to be used one it is final machined and I am buttoning it together.
The part was only the inside machined out so it was 2" thick is some places and .5" in others. I actually prefer to weld fast and hot with multiple passes to fill and cap with something like this.
As to the millions of features yeah you can get lost in my machine in a heart beat if you don't have a map lol. I like it though, I just sometimes feel like flipping one new switch or change something just a tad and boom the welds come out much nicer then you wonder why you didn't do it sooner lol.

Re: Some recent CNC Work
so when you were welding that were you thinking to yourself .."i better not f- this up...."
i know i would haha. with the material cost and cycle time like that id be precticing with a scrap test piece for a bit before laying a final bead, lol.

Re: Some recent CNC Work
I'd certainly want to get some heat in that piece first before I started. I suppose though, if you did mess up, you can just machine/sand that section down then go again.

Re: Some recent CNC Work
It is bolt patterned and made long enough so that it will work on all major Honda motors. Also the opposite side of the plenum is a mirror image as well.
1000whp+ apps only
BTW it welded out much easier than expected and with much lower amps. I guess it was just a sob to tack but that was it.
EP 275 amps
EN 200 amps
Balance 60
Hz 400
Pulse 500pps
50%peaktime
50%lowheat

Alternative Uses For BMC Manifolds
Just testing to fit on my own little Toby dog.
If you decide the Billet Pro plenum isn't for you, it might just be great as armor for your little dog!
PS. No animals were harmed in the production of these images...

Re: Some recent CNC Work
Has it been tested against both human bites and bullets? I'd like my miniature Schnauzer to be protected if she's ever caught in a zombie/military battle.
