Miller Dynasty 200DX options
Tue, 31 Aug 2021 15:04:28 GMT
Hi guys,I'm getting a Dynasty 200 but without torches, etc. The guys at Weldtec recommended their water cooled 'Starter Kit". The thing is that, while I'll be doing Aluminum, steel and SS I'm not a pro welder, just an advanced hobbyist. There may be days when I weld several hours but there will be times when I don't weld for a couple of weeks. Most of my aluminum welding will be thin stock (1/8 or less). I do still have my Miller 210 with spool gun but I may sell it and just get a 252 without a spool gun if the TIG works out.What torches, etc, do you think will work for what I'm doing? Do I really need the extra expense of the water cooler? Is a flex torch the way to go or do they wear out and break more often?Thanks for the help,Rob
Reply:1/8" alum is doable with the "standard" 17 series air cooled torch Miller sells, but it will get hot fairly quick if you weld for any length of time. Go any thicker and you will toast that torch very quickly. I've done 3/16" with mine, but it gets too hot to hold with thin gloves in about a minute and then you have to wait a fair amount of time for it to cool down enough so you get a decent amount of weld time again.If you are serious about doing alum over 1/8", you will want a water cooled torch most likely. If you are portable and don't do much alum over 1/8", you can get by with an air cooled torch. Flex vs standard, can't help you there, all the ones I use are rigid torches.A few things that can save you some cash. Go with a CK torch vs the Weldcraft ones Miller sells. The CK torches are less expensive, and have a higher duty cycle rating compared to similar Weldcraft torches. The Weldcraft 17 series torch is rated at 60% @ 150 amps IIRC, the CK 150 is rated at 100% duty cycle. CK also sells the CK 210 which is air cooled and rated at 200 amps 100% duty cycle. Same goes with the water cooled torches. If I was buying a new WC torch, it would probably be the 20 series CK 200 ove the WP 20 from weldcraft.http://www.arc-zone.com/index.php?ma...x&cPath=13_728Pedals, you can save some money by opting to get one from SSC instead of the Miller one.http://www.ssccontrols.com/homepage-...ngcontrols.htmOpting to go with Millers contractor kits are usually the "easy" way to go, but will cost you more money and you won't have items as good as if you selected them yourself individually..No government ever voluntarily reduces itself in size.

Reply:I would suggest that you forgo the water cooled torch at first, just get a 17 and learn, by the time you learn well enough that you will really have a "need" for a water cooled torch the sting of all the $$$ from the dynasty will have worn off and you can buy it at that point, along with the cooler and all the other bits and pieces... there really isn't much waste at all in getting the 17 series torch in the beginning, it's always good to have a backup torch anyway, in case you ever had a problem with the water cooled setup, and if you ever decide to do anything mobile that requires you to pack it all up and bring it to another location then you will be much better off grabbing the 17 torch and leaving the whole water setup home anyway, so not much waste and less cash outlay right now...miller 330a bp TIGmiller dynasty 200DX TIGmillermatic 185 MIGthermal dynamics cutmaster 101 plasma cuttersnap-on YA5550 plasma cutterhypertherm powermax 30 plasma cutterbaileigh CS225 cold sawetc....

Reply:SS will be straight argon, as will be just about anything else you'll tig... you won't really need any specialty mixes like helium mix for a good while yet.if you have thoughts of doing much stainless then you might want to consider getting a dual regulator instead of a single... it costs a bit more but having the extra regulator tap for back purging SS is a good thing to have, and when you're not purging the dual will do just fine using just one side and the other sitting dormant until needed...miller 330a bp TIGmiller dynasty 200DX TIGmillermatic 185 MIGthermal dynamics cutmaster 101 plasma cuttersnap-on YA5550 plasma cutterhypertherm powermax 30 plasma cutterbaileigh CS225 cold sawetc....
Reply:Originally Posted by robaroniThanks for the good advice. I'll look into CK's 17 size torch. Once I get the machine I may make my own foot control and water cooler. I hear guys are making coolers and I see parts on EBAY to fabricate one.I guess you get a couple of dinse connectors with the bare bones, I'll have to pick up a flow gauge, any suggestions? I've got argon already and tri-gas. Do TIG guys use tri-gas on SS?Rob
Reply:You are buying a state of the art welder and by the time you fool around with components and plugs for a pedal and cable just buy a SSC .I have one on my dynasty 200dx.Do a couple of cash jobs for neighbors and friends and you will pay for that pedal many times over.What is the difference in cost not much in the big picture.Less than a hundred.V
Reply:This is more of a consideration than a recommendation - 9 series air cooled torches (125 amp) use the same consumables as a 20 series water cooled torch. You can see the advantage of not having multiple sets of consumables, and they are both nice small torches for a comfortable grip and tight spaces.JasonXMT 350 MPA Dynasty 280DXSuitcase 8RC / OptimaSpoolmatic 30AThermco Ar / C02 mixerAssorted O/A gear

Reply:I just got the same welder setup. I decided to get the weldcraft ls1725r. BRWelding had it for 190 free shipping. it has built in on/off button, and amperage control. after the sting of this purchase has worn off, I will be getting the scc pedal, a ck water cooled torch, and probably make a custom cooler.Dynasty 200DXPassport plus w/ spoolmate 100victor 315c oxy/(act and prop)Miller digital elitemilwaukee power tools
