AL problem with dynasty 200

Bad gas is a reality in life

I've had encounter a couple bad Argon in the past, especially with cylinders from Liquid Air. Check the sticker on the bottle to see who filled it. The cheaper Argon gas is not filled into commited Argon tanks. That means that they will grab what tank they...

Hawk,

I am switching supplier from a small local welding shop who get their gas from Liquid Air to Airgas. For those that dont know Airgas pump their own gas. The difference in their buying power netted me a very good deal. I exchanged all 3 of my 155 tank to 3 pre-purified 220 tank...

Bad gas....

This is one of those time I wish I can delete the whole thread but on the flip side let this thread stay up and be a learning tool for others.

There is nothing wrong with my Dynasty200.

The problem was in the gas. I have always run 100% Argon...

How is the long term track record for DX200?

After it is out of the warranty period?

HAWK, how do you know about this? Are you some sort of a secret agent?

Should I let them fix it or should I get them to get me a new unit? Do I smell a LEMON?

This is why I buy miller...customer service!

I tried all the settings and suggestion that Dave Fischer and Jake @ Miller gave to me and the weld on aluminum is still UGLY. So I talk to Dave one more time and we finally come to the conclusion that there is something wrong with the welder....

Thanks for bumping the thread back up.

I've been playing phone tag with Dave Fisher from Miller for a couple days. Finally got to speak with Jack this morning and he took my concerns very well.

We went over the gas setting, the torch, the tungsten, and the setup on the...

thanks for everyones reply but...

I am not a beginner to aluminum welding at all. I have welded aluminum for a while and with awesome results on the syn180sd (this is the one where you can alter the balance as well). My frustration (if you can understand it) is that I went out, spent...

I use 4" flapwheel on an angle grinder. I separate my flapwheels, this one is the one that I always use for Al.

I swear I NEVER have this much problem with Al with the syn180.

Let me go over my setting again just incase you can spot something else.
Red tungsten,...

More picture of the same weld bead....

Here's a picture of the weld. Its a small picture. Trying to get around the file size restriction.

You can see the porosity of the bead and the **** speckles!!!!

Hi guys, I have to come up to the list again and ask for more help on the aluminum stuff here with the 200DX. Previously having problem with joint not flowing and not getting a good shiny bead on AL. Andy suggested to lower the Hz and I did that. Now running about 110-115Hz, with 120A on tap.

I need to ask more question on aluminum welding with the dynasty.

I have just upgraded from a synchrowave 180SD to a brand new 200DX in the past 2 weeks. Syncrowave for sale BTW. I have no problem welding MS or SS with it. My main problem comes with welding Al.

I weld...
