    Help me outfit a Miller Dynasty 280DX

    I am new to welding. I figured what is the best way to get better at welding when your MIG beads look like crap? The easy answer is buy a TIG :roll eyes:

    I just bought a Dynasty 280DX and have never TIGed before. I got it 30% off on todays ZORO St Patty's sale. I love the Irish

    I read up on the Miller stuff and it sounds like the cool mate is LOUD and the foot pedal and water cooled torch are overpriced.

    Sooo......other than the Victor flowmeter I bought, what do I need to purchase? What torch, cooler, tips etc? Is there a good cart (or plans for one I can build) to hold all this stuff?

    I am going to sell my Thunderbolt so what else do I need to purchase to be able to stick weld with it? Also, what attachment allows me to plasma gouge with it. Okay, Okay... I know it can't do that but I am still excited to get this set up and going.

    Now I'm off to go watch Jody on welding tips and tricks

    Get a 25' water cooled torch from HTP.
    Foot pedals can be found everywhere.
    Just a couple welders, big hammers, grinders, and torches.
    Work will free you.

    Well it sounds like you elimated the water cooled torch option which is completely fine. A WP-17 Air cooled torch with a flex head and gas valve would be a perfect torch for you. I know it may sound odd to get a gas valve torch since your machine has a solenoid in it, but it makes your rig more versatile. Those Air cooled rigs are good for up to 150-180 amps, but will start to smoke your hand if you keep welding on it past 150. They do make HD WP-17 rated up to 180 amps which is what I use. Your gonna need 3/32,1/8 RED tungsten, and 3/32, and 1/8" GREEN tungsten. Red for most ferrous materials, and green for aluminum. Your gonna need filler wire, ER70S-6 or ER70S-2 good common carbon steel filler rod, get that in 3/32 and 1/8" as well. As far as common aluminum filler I am not too educated on. Your also gonna need a bottle of argon, preferably a 100+ cf bottle.

    I use 2% lanthanated in 1/16 and 3/32. That covers me for everything I do on AC and DC.

    I picked up the machine and then pieced together everything else. I bought the wireless pedal. Then everything else came from HTP for the most part. I picked up their cooler, 20 series flex head, and ground clamp. I also have a 9 flex head for DC work from my previous machine. I'm very happy with the HTP products.

    It's a great machine. You'll love it.

    When you say I eliminated the water cooled torch option what do you mean? Should I have ordered a different model?

    You have the welder.

    You can put a good used Coolmate 3 under it for $300 (or purchase the new Watermate Showdog has for sale here)

    Buy your choice of torch (I went with a CK SuperFlex Trimline setup and used Weld Tec connectors & quick disconnects)

    Buy a new pedal from SSC controls. They're under $175 shipped to your door. I bought the cordless pedal and I love it. Worth every penny.

    Throw a ground lead on it and you're good to go. Like zank said, you can buy most everything from HTP (usawelds.com) You can put an air cooled torch on it for the time being if you don't have immediate funds for a cooler. You can pretty much set it up how you like. There are no real limitations, except the size of your wallet

    IMHO of course

    I think he misunderstood your comment on the coolmate being loud and thought you wanted to go air cooled instead.


    With a machine with the output that one has, I'd go water cooled so you can make the most use of the power available. A CK 20series water cooled torch like the CK 250 would work You can get it in several versions like the standard torch, flex head or swivel head. I'd just start with the standard head myself. You can always change later if you find a need for one of the others based on what you need to weld.

    SSC makes reasonably priced pedals that would work. I've used the wireless Miller pedal and it's nioce if expensive. Depends if you want to sp[end the money to avoid the cord. I can make do just fine most times with the corded pedal myself.

    Oh, a Coolmate 3 is one of the best coolers on the market. About as quiet as they come. Last forever and hold an excellent resale value too. $300-350 will get you in a very nice used one

    Welder.

    Coolmate 3

    Ck 25' SuperFlex TIG torch (in whatever configuration you like best)

    Weld Tec Dinse connector and spin on quick connects for water and gas

    Miller wireless pedal (or an SSC one, they're cheaper than OEM)

    1/0 ground lead with Tweco solid copper clamp

    Build your own cart.

    Think that about covers it

    Yeah, inverters change what you thought you knew about TIG welding.

    Re: Help me outfit a Miller Dynasty 280DX

    Since we are on the topic of tungsten, I'm used to using Thoriated on a Maxstar 150 with SS and mild. I was reading the description on the various tungsten and I can use 2% blue's for SS, Mild, and Alum. I know Zank said the same thing but I just want to get some more opinions on the subject. I think I would need to keep separate tungsten for metals?

    Re: Help me outfit a Miller Dynasty 280DX

    Lately, I've been using the same 1/16" 2% lanthanated prepared the same way for both AC and DC. Granted, I don't do much in the way of heavy wall. The threaded shell in this picture is 0.150" wall, which is about as thick as I go for most of my work.


    Random by Zanconato Custom Cycles, on Flickr

    This steel frame was done with the same electrode.


    0306151636 by Zanconato Custom Cycles, on Flickr

    This is how I prep all of my tungsten for both the steel and aluminum frames.


    1/16" 2% lanthanated initial prep by Zanconato Custom Cycles, on Flickr

    This is what it looks like after welding one aluminum frame.

    Arc starts are excellent on both AC and DC.

    Hope that helps a bit!

    Couple questions on the fixturing…

    HTML Code:

    "

    Hey Zank,
    In your 1st pic , is that an allen head threaded back purge device inserted into the pedal spindle bore?

    2. The spiral springs on the allen head bolts on the fixture are to prevent scratching the piping?
    Just wondering

    This is why I bought my 200dx in package form. Congrats! I still have to buy a plug setup and argon and a helmet! And like you I have zero tig experience.

    Re: Help me outfit a Miller Dynasty 280DX

    To the Op -- nice job -- I did the same thing!!! -- Got a tracking # and my machine should be here Friday -- that price was unbeatable

    I am not new to tig -- been using a 251 HF box off my miller 250G Trailblazer for a few years now -- this inverter is going to change everything for me

    I have a CK flexloc torch, water cooled -- Will the CK safeloc dinse connector fit the dynasty? I though I read that there where some issues with depth using dinse connectors other than Miller

    How about the ground lead -- Does a dinse connector come in the box for that? I bought 200 feet of 1/0 cable from electron beam tech a few weeks ago -- Needed some for a few projects and knew I was gonna buy a dynasty fairly soon

    Your happy that you bought your Dynasty as a package?
    You lost money there.

    For me personally; it was money well spent. That's just how I feel about it. Dx machine, coolmate 1 with a gallon of coolant, wireless pedal, watercooled torch with 3 different sized cups and 3 different sized tungsten electrodes, a regulator/flowmeter and gas line for your argon, a cart with wheels 2 roll it around on. A total newb like me just has to choose my plug, buy gas, filler, and safety gear and go. Sure an experienced weldor might have some or all of this and knows about a cheaper cooler here, and a better pedal there...etc. But for ME , personally, this was the best deal. Ordered and delivered to my door in 2 business days. I think I did alright.

    Add to that the exact same package from the exact same seller on line went up $192 from the time I ordered to the time it was delivered. I must've ordered just in time!

    I suppose that avoiding the hassle of buying all the different parts from different places was worth the extra money.

    I just like building my own custom package, and saving a little money.

    That was probably the scheduled Miller price increase for 2015 --

    Re: Help me outfit a Miller Dynasty 280DX

    Why do you want to limit a 280 amp welder with a 150 amp torch? I bought a SSB foot pedal, a Weldcraft 280 torch, a coolmate 1.3 cooler, Tungsten could be anything but green pure. It dissolves into big droplets of liquid. Lanthanated is nice. I have gas lenses in 4 sizes, Cups range from #8 down to 4. I rarely use other than 8. I have but haven't used .020 and .040 tungsten. 1/16, 3/32, and 1/8" A dedicated grinder is a must. Mine is DeWalt about $120.00 I found it on sale at $100.00. You also want a dedicated 4-1/2" hand held. I use aluminum hargd grinding discs from Radnor, Norton Blaze soft disc. Wire brushes in stainless and steel.
    Acetone, and a flat cookie pan.
    An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.

    The electrical cost of welding is so expensive that you need to bake cookies at the same time to cut costs.

    Seriously though, whats the cookie pan for? I haven't done tig long enough to know any trade secrets/shortcuts.
