Aluminum/Dynasty

[Wheels]

Finally made time to try out the 200. I`m trying to post pictures, but the file is too large. Any suggestions? My file size is 116000 bytes.

Wheels,

What is your file type? JPEG? If it is a JPEG, try using your printer program or photo editor to reduce the file size. Your program probaby has the provision to change DPI and inches or pixels. Change DPI to 72 and choose inches rather than pixels. Change to 2x4 or 3x5. The right mouse click the file and choose properties. This will give you the new file size. If it is plenty small, but fuzzy, increase the DPI to 150 and save as a new file and check the properties again. Email me through the forum with the programs you are using and I'll be glad to give you specifics.

Wheels,

What do you think of the machine? It looks like the filler flowed in nicely. What settings are you using?

[Wheels]

I was using 5454 alloy 1/4". 2% thoriated that came with the kit 3/32.
75% ballance,100% argon ,130 amps , 120 h/z. Somehow my settings don`t sound right, but this is the product of only about two hours of fiddling around. Far better than I had hoped for.

Thanks for the insight.

Mike,

Pick up some 3/32" ceriated tungsten. Grind to a point and put a flat on the end. Kick your arc frequency up to 150HZ. Give the torch a little more counterclockwise movement as you advance it. You might even turn the amperage down by 5-12 amps with the frequency kicked up. Try it. I think you will be surprised. Keep us posted. If you don't need the 5454 alloy, try 4043 for the smooth flow. Although the 5454 fell in nicely.

Yea Hawk I meant to say the plate was 5454. Left over from a dump bed floor job . I always have scrap aluminum around here. That is a good thing for practice. I ordered some ceriated over the weekend. This flowed so well it is hard to believe the ceriated could be any better,. It`s kinda funny ,I do a lot of mig al. and am always concentrating on starts, now i have to work on my stops!
I could also use some practice on posting pictures, I screw-up enough to keep everyone entertained for days.

Thanks Mike

Wheels,

Well you got it posted and we all make mistakes. I figured you ran a lot of AL mig from your bead profile. This is not a bad thing! Sometimes I pour it in like you did this one and sometimes I stack the dimes or go wider and stack nickles. It just depends on the application. Once again it looks like 2 hours has really been kind to you with the Dynasty. I believe you will like the way it responds to the increased arc frequency. Let me know. The ceriated will weld better and it is not radioactive when you grind it as is the thoriated. It also works better when you have to lower the EN balance. If you are running at 65 or better the thoriated does fine. Somewhere around 50 on the EN and you will really appreciate the ceriated. I hope don't have such nasty alloys as to need the 50% EN, but it happens.

Should I have tigged this?

One more. A shot out the back of an 18 foot dump bed . This is a liner installation finished up last week.

Now that would really look great with a nice stacked nickel bead!

from you pic it looks like your to hot, i am not very familiar with the dynasty but i would heed all of hawks advise and then i would watch your heat input, so you get the stacked dime effect, brian

[Wheels]

Yes I was running too hot, I just couldn`t get it in my pea-brain that a toaster-sized machine has the punch this one does! I`ll take Hawks advice and go down with the heat and up with h/z this evening.

Wheels,

I have found, in my very limited experience, that I have to back the foot pedal off quite a bit by the end of a run. The heat really builds up in the aluminum and the bead will widen and flatten out pretty quick.

I still really suck at welding aluminum but I have found the Dynasty very easy to setup and control. Any problems rest solely on my shoulders.

Bob.....Bet you I have done something you havent thought of yet. Took a break to feed the face, turned the gas off, came back and proceeded to melt my tungsten because I forgot to turn it back on.

Little bit of Homer Simpson in all of us I guess.
