    Question

I decided I wouldn't wait for the coolmate version as I felt that non coolmate version would have better airflow regardless and its not that big of a deal for me to plug it into the wall

    So it does sound very much like there is an aux inverter board inside the water cooled version of the Dyn 280 to provide the 120vac for the coolmate..

    wish one of the TECHNICAL folks at Miller could clarify and shed more light on this.....

    sounds more like a "FIX" rather than a component that was planned for and integrated into the overall design from the beginning..

    They also told me that its not going to control the coolmate at all. Just provide a place to plug the coolmate in and that's it.

    Thanks everyone for your interest! There is a pretty substantial difference internally due to the fact that the water-cooled models will have extra components that are necessary to generate the power for the cooler. The power for the cooler will be available in only the models for water-cooled use - this could be a power-source that someone purchases to use for air cooled use temporarily but intends to pair with a water cooler at in the future or it could be a complete runner package.

    There will be two cords available in order to plug the cooler into either a water-cooled power-source or into a duplex receptacle. Any complete runner packages will come standard with the appropriate cord to allow the cooler to be powered through the dedicated use receptacle. Please stay tuned for more information as we approach the release of those models in the next couple of months.

    Since there does appear to be a substantial difference between Air Cooled and Water Cooled power supplies...

    What is the price differential between the two??

    I have been waiting a week for price confirmation.

    I have been welding thousands of small parts keeping my Dynasty200 quite busy. So far I have about 5000 small parts to weld, 50 array systems, 6 cavitation reactor systems, and a couple of ground support structers before the end of the year so I am ready to buy. That is why I have been offered a loaner until the water cooled unit is available. At that time I can take my 200 back home where it belongs.

    Thanks for the welcome. Hopefully I can be some use around here.

    I will wait for the water-cooled version; but i will make sure to trade it in for another Dynasty 280 about 2 years 6 months into the warranty. I bought my Dynasty 200 new in the very beginning when Miller came out with it... I should have traded it in once the blue lightning and waveform updates came along. Now my HF board just recently gave out and I've been using it in lift arc mode only.... but I can't really complain because I bought it new in 2003, so it gave me 10 good years. Back then, they didn't have the full 3/5 year warranty... The updates to the Dynasty 200 came along because of problems reported in the field. I will be selling my Dynasty 200dx on ebay really soon, I think it will still command a good price even with a bad HF board. The LWS wanted $1500 to fix it, but I just paid the $85 inspection fee and decided to let the purchaser fix it themselves by ordering parts from miller4less.com instead of trying to dabble with it myself.

    It isn't totally obvious about the auxiliary power connection issue. Miller alluded to it but didn't make it completely obvious about what is going on. The problem they have is the power feed to the 280DX is 220v, not 110v. Therefore to supply 110v power to the Coolmate requires another smaller power converter to be included in the 280DX. It will undoubtedly be solid state in order to keep that 52 lb. weight goal and keep the packaging of the unit the same - not a simple task. The purpose of the special connector is to make sure something is not connected to the unit which will exceed the max power of the on board power converter, as it is being designed for the Coolmate 1.3 electrical requirements, nothing else. It will probably have short circuit protection, but overstressing is not a good thing.

    The more I think about it I will be inclined to get the model without the water cooled power option. Its just something else that can go wrong vs a plug going to a 110v outlet.
