Dynasty Processes-Set Up

[Invader28]

Thanks for the info Mike and yes please keep us informed on your experiments. I haven't played with the ratio going the other way so now I'm going to experiment as well.

solid slick welds on the frame. the 280DX is like how you say...so much more tweaking than just manufactures recommended settings.
keep thumbing the rod!!!

Dynasty 280DX Pulser function

Hello Group, Recently stepped up to an inverter to enhance my alum. welding game. ( have been using a Syncrowave 250DX for years)

The parameter choices seem endless on the Dynasty 280 DX, and I love IT!
Still practicing, starting with Pro-set features till I figure it all out.

My question: can you weld Alum. with the Pluser ON ? and what if any benefit?
The Owners Man. (sec 15.2) mentions PPS lower settings for helping with Porosity on alum. and the Background amps set between 35--50%.

I am just a little unclear, (haven't tried it yet) I thought when I used my syncro. Pulser it was a DC tig function only.

I am a 30 year welding Novice, Practicing a lot, trying to improve.

Any and all Insight would be appreciated

You bet. You can run pulse on AC. In my experience though, it is generally only helpful for timing. I have used it a few times for very thin (<0.020") applications to keep the heat from getting out of control. But I do those same joints now with straight AC current.

I really like high speed DC pulse though. It gives me a little more control on edges and I can generally travel faster.

All that said, experiment! Figure out what works best for you. That's the beauty of it. The pro set settings are a great place to start when you try the pulser. Work your way from their and take notes.

Have fun with your new machine! Keep us posted on your findings.

Thanks Mike, I will do that, my ultimate goal is to get my welds looking like yours on that bike frame, awesome work.

Tungsten after welding out the front triangles. Now granted, this isn't a ton of welding. But I think it help up amazingly well.

For reference, the head tube is 2" OD x 0.145" wall. The threaded bottom bracket shell is 1.75" OD by 0.160" wall. The three main tubes vary between 0.052" and 0.074" wall. Material is 7005 aluminum. Filler was 5183.

If you've made it this far, I hope you found the info useful. I'm going to keep experimenting with wave shape and I'll put up more info if people are interested.

I keep coming back to what Dave Powelson has typed quite a few times. There are an infinite number of ways to set up these inverters. I'll add to not get boxed in by the recommendations. Experiment a lot!

I have had my Dynasty 350 now about a year and a half welding and repairing mostly aluminum heads and engine blocks,but recently started fabricating a sprint car fuel injection intake manifold trying to get the nice welds like your's and have been doing a lot of experimenting to get really good looking welds, and started doing exactly what your doing and i am getting the same results,i'm still dialing things in and like the results,welding 6061,.065 to .250 using 4943 filler.

This thread should become a "STICKY" again...

somehow it fell off during the recent upgrade

Question? I have an opportunity to buy a 2005 dynasty 300 for good price,or should i wait and buy the dynasty 280 for $5000. more,with 3 yr warranty.

I would go with the new Dyn 280.... remember the 3year warrantee on a new machine...it could mean a lot..
and the technology has progressed a lot over the years

if that 10year old Dyn 300 fails it might be a very expensive and disappointing process.... it has a reputation of being difficult to repair

there are some old threads on it...

foolwelding what did you buy ?

Ihave been on the phone with cyberweld about 280dx,the guy was telling me i need an 80 amp breaker for single phase,and that the 350 only a 60 amp,have miller teck line phone number, will call tomorrow for better info,really looking at the 280dx

I thought he was wrong... but the book says

Single phase 230VAC... the Dyn 280 wants to see a SloBlow fuse or breaker of 60amps... normal fuse of 80amps

It surprised me... maybe one of the Miller factory Techs could comment..??
