Much of what you want to discuss is probably considered proprietary,
especially when automation is being employed with the Aerowave.
I can comment on the Dynasty's performance and reliability. In my opinion, this and Thermal Arc's GTSW 300 are the best thing to come along since AC TIG welding was developed for aluminum welding. We have Dynastys in use, both in the field and in our facilities, some are three years old. So far we have only had one board problem, which was covered by warranty. We don't use the Thermal Arcs as much, but, have not had any issues.
When it comes to fillet welds, these machines definitely shine over the old snycrowaves.
I like the first version with the knobs better than the digital read outs, because the welding personnel are used to knobs and scales, so it's easier for them to set. They have adapted to the digital read outs with out too much difficulty though.
With these machines the days of pure or zirconium tungten with a balled end are history. I find a 2% Ceriated tungten sharpened to a point, with an angle face that is two times the electrode diameter in length works the best. For manual welding Argon was always adequate.

I have both machines. They are the ultimate in AC/DC arc performance. The AEROWAVE is better than the Dianasty.
The AEROWAVE can change wave form up to 400Hz, the Dianasty 250Hz. The AEROWAVE will pulse 500 PPS, the
Dianasty will pulse 300 PPS. If you weld with these machine you"ll throw rocks at your G.T.A.W. machine. I have my
AEROWAVE forsale on the AWS equipment website. I don"t need it any more, I have come off the road as a welding
consultant to take a Teaching job in a high school. I have the Dianasty in my lab @ school. It is the older model with
the knobs. The students use it so it is kid proof, they can tear up a anvil. Spend the money you won't be disapointed,
the Quality of your weldments will imporve your bosses hemarolds.

I think you have a good topic, but as stated in one of the responses, most of this infoemation will be proprietary information. A fabricator who paid to qualify a procedure may not wish to diseminate the information he/she paid to obtain. Many of the gas distributers are reluctant to divulge the specific compositions of their mixed gases. I work with pulsed GTAW and GTAW on a regular basis on a variety of materials, BUT, I do not share information I have obtained through R&D (why would I do someone elses homework?)

I have been asked to permit an individual to "copy" WPS's/PQR's that I developed and qualified, again, why would one do the work for another? I never divulge specifics of my research - that is how I earn a living as a consultant. Heed caution, there are some who don't have a problem duplicating your effort!

I am curious as to the responses of your post. I'll check in now and then to see if others don't mind sharing information, after all, were all in the same biz...
