    hey Sundown,

    your daughter will do well there its a very good college and the area's real nice. If you ever make it over to visit her you'll have to drop by my shop and burn some rods
    Funny enough I was working in Runcorn last year for 3 months so I know that area pretty well too.

    Really is a small world!!!

    zirc gives a good weld and ***** up well - not problems starting.

    i only use gold tips nowadays and have had no trouble with starting with my 200 dynasty.
    We can get zirc's no problem but most have settled on either Ceriated or lanthaniated. I settled on 2% Lanthaniated (Blue) for everything as it make is easier to keep stock without worring about different tungstens.

    I see you are from Bath, my daughter will be going to Bath Spa collage in just over a year from now, she did a visit last christmas and was very impressed. Her boyfriend lives in Runcorn and will be here for the summer this year. Small world ... Cheers.

    I agree with Sundown. Also what is your pre-flow at. I had a dyn 200 and it would also do this. I upped the pre-flow a little like less than a second I think and it started fine after that all the time. There are also arc start menus you can go into and set the start up amperage. It is in the manual. I forget what buttons to press to get into this setting. However before doing this you also might want to try to restore the factory default settings of your machine. Try it that way first then if that does not work you can play with the menus.
    Look in the manual again for the factory default settings.

    Orange woud be 2% Ceriated and that should be the easist to start. For .080 aluminum I would set the max amps to no more than 100, most likely 90 to start, Balance on 70 and freq on 120. I would switch to 1/16" (3/32" should work also) tungsten and taper it to 30 degrees with a .010 flat on the tip. Be very sure you have a good ground. When I first got my Dynasty it would sometimes do the same thing, I removed the cover and ran a very clean .009 feeler thru the points and have had no trouble since. Just stuff to try, let us know if you work it out.

    I think I am. It's the orange colored type, isn't it?

    I've seen this problem come up before, and I also have the same sort of difficulties some times with my 300dx. Try switching to a 2% thoriated, I found it a little better than pure, but I think the best tungesten to use is the lanthanated kind. When I first tried out the dx model 4 years ago, I found it worked the best with lanthinated, when I changed over to another type, the hard arc starting was apparent.

    Dynasty 200 DX problem

    I've got a new Dynasty 200 DX and I'm having problems with getting the arc started on some .080" aluminum I'm welding. When I have a freshly ground tungsten, it will start as normal (I'm using a foot pedal), but after the first use, the tungsten will get a small ball on the end and then the arc doesn't want to start again. It will just make the frequency ticking sound and get some static arcing, but not get going like normal. I'm using a 3/32" tungsten, with the AC balance on 60 and frequency on 130. If I start moving the torch around (increasing the distance to the aluminum) it will sometimes start. I'm running about 145 amps max setting.

    Any ideas?
