Esenti, on your machine, you might want to try setting the offset at +20% as a starting point.

On the HTP 221, I'd probably try setting the EN at 70-80% as a starting point.

[zank]

My pleasure guys. Please post your findings as well. These inverters are pretty amazing. We all need to learn from each other. Sometimes a solution to a problem requires going off the beaten path.

Zank;

You're killing me here! I want detail! What did the upgrade cost? Where did you buy it? How do I install it? Months ago when Terry (Shovelon) talked about the 350 with amplitude I started having buyer's remorse. I take it it is now available.

[zank]

Bill, it's part number 301235. Retail is $499. Maine Oxy ordered it for me locally. It was brand new when I got it, so I couldn't find it online. The card goes in the SD slot and stays in.super easy. The other cool feature that I haven't really dug into yet is you can change the waveshape for each half. So, for example, you could have tri wave on EN and advanced square on EP.

If the big jolt of amps on the EP side is what is truly doing the oxide-breaking more so than the time-based balance shift, which based from your findings it indeed is, I'd suspect that using a triangular wave on the EP side to keep the amperage peak high, while lowering the overall heat back into the tungsten more so than an advanced square wave will help out just as much as using more EP:EN ratio and keeping the EN% balance up higher near 100% as much as possible. Think "area under the curve".

Amazing what lines of code will do in the real world. Just a bunch of 0's and 1's on a chip. Yet the results in reality are magnificent.

The wave form is also adjustable for each half??

While that is actually super cool.....Holy mother of crap! Imagine the Noob questions that are coming in another couple years.

When we tell them to list their settings before we can help, the list will be 50 items long!

Then after reading all that, and them trying 200 different combinations....
.....the problem will be they were running 75/25 gas the whole time and didn't check when told.....

I better go wax my Airco and give it a hug

You'll need a lot of wax, and big arms. The Airco like a big woman gives a lot to love, and throws a lot of heat on a cold winter night.

Yup, each half of the waveform shape can be set independently. Good thing noobs can't afford the software upgrade, let alone the machine.

If I ever buy another TIG, it will either be a 280DX, or a 350DX. Or a Stel (HTP) if they ever decide to give either one of those Miller's a run for their money. It would likely be $1500 cheaper. I can only dream

[Drifta-X]

Wow, very cool indeed!!!
Don't want to buy the everlast 210ext quite as much now lol.
But think still be awesome first welder.

Yep - I know a little about that "gives off a lot of heat" part

I like Miller and Lincoln products just fine - but when the government outlaws my Airco for using too much power and being too simple to operate, HTP might get my order

[Superiorwelding]

zank,
I have been following this thread and first want to thank you for sharing what you have found and being so helpful to us all. I don't even know where to begin as far as questions. One of the first ones that came to my head is I wonder if the Lincoln Aspect 375 has this capability as well? My next question was already answered so far as being able to adjust different wave forms for both the EP and EN side. Correct me if I am wrong but since you have more amperage on the EP side shouldn't your electrode see more degradation with longer use that it does now? Looking at the sample welds (which I still don't like you for ) I see black smoke on the edges of the cleaned zone and a little in the weld itself. Is this from the material or the fact that there is to much cleaning action pulling impurities into the weld? Also, how in the world did that 1/16" tungsten hold up to that amperage? And I can go on and on

Jonathan the Aspect has the same features with the acceptation of splitting the wave, triangle one side square the other side etc. You can split he wave with the V310T but it has no adjustment of the EP EN beyond the balance.
When I was messing around with AC on the Aspect I was able to keep a darn near needle sharp 3/32" E3 tungsten at about 100 amps with a triangle wave but I never saved the settings. I was able to make about a 1/16" fillet on a 1/8" lap joint using 0.035 mig wire, wasn't pretty but I was amazed at the control you have over the arc.

Its hard to focus on experimenting with things and keep an eye on the shop and help the students at the same time. I'm looking forward to getting back to school and try Zank's settings. Thanks for starting this Zank!

Blasphemy!

Few can weld like zank , so I declare fun and follower of Zank and i will start experimenting .Actually i have already did and seems there is a lot of improvement . There must be the perfect equation for each machine where you can achieve the perfect welding .Im Pleased so i want to dedicate you a poem of KAVAFI

I had some time today to play around with the Aspect. The settings for the pic were 400 frequency, 85 balance, 50 EP and 150 EN. Since I started experimenting with the EN EP stuff I decided to make one of the numbers 100 or 150 and set the other as needed since it is basically a ratio anyway. Changing the EN EP values will change the max setting you have set the machine at so if I don't have enough amperage I just turn the amps up and the ratio of the EN EP is preserved, their values just go up and it gets difficult to keep track of the ratio. This is probably and extra step but it makes it easier for me to keep track of changes I'm making.
It's not pretty I know but that is 1/8" material so that is like a 1/16"/3/23" fillet. I used 0.035" 4043 MIG filler, tungsten was 3/32" either E3, Rare Earth or 2% Lan the color is worn off and those are the three I typically use. The tungsten stayed pretty sharp but I think I can keep it sharper by tweaking the setting some more.



It just amazes me how flexible this and other machines like are with AC.

John

[weldin mike 27]

A lap weld on 1/8 material and you were able to leave the top edge, on aluminium? I'd say its a winner.

Mick

[WTFH]

Thanks Mick, I was a little shocked how focused I could get the arc. Like Zank said its pretty close to DC tig.
BTW I was using a triangular wave.

Hello from a new member. I am trying to find more info on the independent amperage upgrade for the dynasty 280. I called my LWS and they said that it was not available. I called Miller directly and they told me it was not available. Any help would be greatly appreciated!

I'm a welding instructor for 11th grade students and I use Jody's videos every week. The students really enjoy tem. I'm a CWI and do some aerospace work on the side and I'm working on my first bicycle frame. I use a Dynasty 350 at work but I'm looking to upgrade my home TA185(awesome machine) with a Dynasty280. Thanks
