    Note that many of the inverters are single and three phase. Unfortunately, many of them have significant derating on single phase power.

    Note that the Dynasty 350 duty cycle chart for single phase tops out at 30% duty cycle at 250 amps, per the owners manual. Miller says that you can probably get more than 250 amps of power out of it, but at a very low duty cycle. Of course, on three phase, they rate it at 350 amps at 30% duty cycle.

    Another plus for the Synchrowave, then, is the lack of derating for single phase, as the Syncrowave is single phase only. On single phase power, the Syncrowave 250, at 310 amps, is really more powerful than the Dynasty 350.

    Very good. Had not thought of that. Noticed that PFC for Syncro 250 and 350 is an option. Why not include it and have a bypass option for low idle power savings?

      My .02 on PFC (Power Factor Correction).

      While PFC may benefit a large shop which is running the machine in a production environment due to lower "arc time" costs, the disadvantages far outweigh the advantages for the small shop/hobby user.

      Power demand for a PFC equipped machine, are significantly higher when the machine is idling. No such thing as a free lunch.

        Problem is without PFC, and in the hands of the hobby welder, let's say in the garage, power surge at the beginning of each weld will require a much higher rated service panel, and that isn't cheap. I would rather put that money into an inverter.

        Otherwise purchasing the PFC option will cost another $500 or so. Again, I would rather put that money into inverters.

        I purchased one Sync 350 without PFC, never again.

          Don't really know what Miller has in mind for the Sync line. But I do know 2 new variants of the Dynasty are scheduled for debut next spring.

            Great.

            Two new variants of Dynasty scheduled for spring.

            Guess I better be putting a few pennies aside in case they offer us a 250/275 Dynasty. Been pushing that train for a couple years now.

            Just what I need. Another tig welder in a one man shop.

            One things for sure though. There will ALWAYS be a Sync 250 in the corner of the shop.

              350lx syncrowave has anyone had on/off switch problems?

                  as trying harder to sell the newer, more expensive technology.
                  Copper is expensive. It's reasonably likely that circuit boards are cheaper in volume.

                  Consider the trivial cost of even the best PC motherboards, or the increased parts content in a Victor Edge regulator offset by the reduced amount of brass...

                    Dynasty 250 ?? !!

                    Andy,

                    Is it TRUE ? Portable and with the Blue Lightning technology, I'm guessing. Those of us that are doing mobile marine aluminum and anodized work are spotting at this point !! Hurry up already.

                      Now that I'm finally all set to place an order for my very own Dynasty 200DX, does anybody here think there is any chance that Miller is going to be adding anything to the lower end of the Dynasty line?

                      I've wanted a 200 since someone on the road-show truck mentioned that Miller was about to announce an auto-line, very portable, about 200 amp machine below the Dynasty 300, and that it was in beta testing. Now I have finally saved enough pennies to have one.

                      If I wait and they improve the 200, pricing it higher at the same time, then I'm back to saving. If I buy now and the 200 gets better for the same price, then I'm going to be kicking myself.

                      I'm tempted to say, just like buying a new computer, buy the best thing that is available when you have the money, because chasing what is about to be released is a sure way to make yourself crazy. Only gotcha that I see there is that the welding products industry doesn't move nearly as quickly as the PC market.

                      Does the hot metal version of Dear Abby have any advice?

                        [QUOTE=SundownIII;267951]My .02 on PFC (Power Factor Correction).

                        The benefit of PFC is that it lowers current flow on the power wires. If your welder is properly fused and you aren't doing long runs of wire, it will do little to add PFC. In fact most (if not all) households are billed on actual power usage not apparent power. So there is zero savings for them.

                        Commercial users are seen by the power company as users of electricity during peak times. As such, the total current draw on the power grid is a concern and if you your PFC is too far out of wack, you get charged based on apparent power (Take your peak voltage x peak current) and you effectively get charged for power you can't use.

                        Check with your power company what the changes in rates are an what kind of PF you need before you spend the extra $. Some power companies only require PFC of .90, some want .95. etc.

                        Might want to check your electrical bill, they should itemize it and tell you were your at.
