    considering that its pretty **** old and if size is going to be a issue for you.... plus i couldnt tell if it was 1 or 3 phase ?

    for the $3500 you could get a nice syncro 250 tig runner or a dynasty 200 that comes with a 3 year warrenty !!

        single phase 200 amp service at 220 volt yes I thought it was expensive also, but, and Iknow this will open a can of worms, it will do 500 amps of squarewave a/c, That seems ridiculus but I do do a bunch of copper work that requires me to preheat, and maintain a burner beneath, even with 375 amps.maybe the dynasty 300 with advance squarewave technology can weld this stuff but even on d/c 375 just barely gets me by.

          make him an offer

          if he is in your back door go see it and make him an offer

          he may make you wait out the action or if no bidds on it he might just pull it for you

          if you got $$$ in hand it is a verry perswasive tool

            try it

            take some of your copper to him and try it out. it could be well werth the drive even if it just tells you it wont do what you want.


            HAWK should be able to give you an ideal of how well the dyn.300 would do

              dyn88,

              I don't do much with copper over .090". I don't think the D300 would really help you since you are welding with DC. Don't get me wrong it is a great machine. However, most of its but kicking abilites favor AC welding. It is always a possiblity to try welding on AC with a 95%+ EN balance effectively welding with DC to a great degree and see what happens. How thick of Cu are you welding and what joint design. I would not mind testing the D300 and letting you know what it will or won't do. As you already know Cu is a great heat sink and it does not have to be really thick material to present problems when welding. What are you welding at 375 amps DC? 1/4"???

                HAWK its realy funky the preheat is penned at 750 degrees but dwindles quikly even with a burner underneath. its 1/2 plate about 2 feet by 16 inches with 1"x1" x 8" blocks with a fillet. A/C works much better but cant get the heat input out of it. The fillet is supposed to be 1/2 but the engineer cant find anybody to even bid the job let alone do it so I get a 1/8 fillet and no failures yet. The original looks mig welded but noone can offer advise on how. they are uekranian parts that we are rebuilding for a large electron beam gun that vaporizes ceramic. Very hot internal temps(12000 degrees is whayt we are told ) all the critical parts are water cooled. No brazing allowed on the hard parts though.

                  dyn88,

                  Let me see if I can find some similar material and see what the D300 will do. I'll try to call some material suppliers today. Do you have any scrap material?

                    Ive got some scrap leave your address and ill ship you some material and rod! Thanks for the interest.

                      Dyn88,


                      I currently have a customer that tig welds copper with a syncrowave 500, newer model though, well newer then the one your looking at. Most of his peices are between 1/2" and 5/8" thick. It's a good machine, if it'll do what you want it to do. I diff. would take a peak at it 1st and see if it's going to do what you want it to do. Currently this customer is looking to mig weld his peices together now, and we're currently looking into using either "red" or Miller, for miller it's the XMT456 pulsed with .045 and 90%HE/10%AR gas. Not sure of wirespeed or voltage but xray's and tests came out better then expected. This might be something you might want to look into too.

                        dyn88,

                        Since I am unable to email you through the forum, send me an email at
                        [email protected] and I'll get you an address. It sounds interesting at the least. I have a couple of good ideas to get the wider fillets with less amperage. However, they do take advantage of the Dynasty's advanced AC arc wave.

                          Another solution to welding thick sections of copper or aluminum or anything, is with plasma. You can add a plasma unit to you current TIG welder and increase your heat input by 50%. The plasmas columar arc is 50% more intense and will more effeciently join your material. Perhaps you could elininate your preheat and tighten your haz. Also, you could use Helium as your plasma gas to increase arc voltage and arc pressure and keep argon as your shielding gas. You would also have the option of piercing your material and keyhole welding your butt joins.

                            I new iforgot something in my description. I use 75heand25ar already! Can you drop a link to any plasma manufacturer? not at all familiar with the process.
                            just got a quiky education on plasma welding processes, it seems like the way to go, can you tell me where I can price out the neccasary supplies?
                            Ive googled for manufacturers and it proves to be an odd process. Im all for it though.

                              There are several manufacturers that build 10 amp and 100 amp plasma units. But when you get to 300 amps, there are few choices. AMET could build you one identical to what NASA uses for $65k. Liburdi could build you one for $47k. Or i could sell you a "plasma console" that would add on to current Miller tig welder. If you only need DC plasma, then we could put it on a transformer, but if you need AC/DC, then we need to put it on an inverter.
                              The largest hand-held torch avaliable is 180 amps, but if you to go with a machine torch, you could pump 300 amps. I could build you a plasma console for around $7k plus the torch. Let me know if you want to see a spec sheet on the unit.
