dynasty 200 question

[drichmond]

well i'm a newby to posting so here i go got a new dynasty 200 dx and l am having a problem most likely it's me but when you set machine up as in the manual and go to weld ac or dc you only have lift arc which is ok initially but on previous welders i have used when you step on the pedal you will get a arc off of the tungsten not so with this dyns.what am i doing wrong? This board is visited by me a lot and i know there are some very smart welder type's here so i'm sure my problem is something i am doing wrong thank's

Check your panel and make sure t is set to Remote HF. It sounds as though you have it set to lift arc.

thanks but i do have remote on and light for hf is on but no hf start

Don't feel lonely

It just bought a new 200DX a week ago & my HF start will not work either. Lift-arc works pretty good tho'. I need the welder right now or I would send it back to Miller.

Have you prepped your tung properly and are shure you have the correct shield gas and flow?

When you step on the pedal, do you hear some repeated sparking? If you don't hear anything like that, then your HF board is most likely defective. My HF was busted right out of the box and apparently it is pretty common with new D200DX machines. Talk to the folks you bought the machine from. Most likely they will exchange the machine for another one. Do that before trying to bring it to a Miller repair guy. I bought mine from Cyberweld and they shipped me a brand new one and let me return the defective one once I received the new one so that I wouldn't have any downtime.

If you do in fact hear sparking, there's some other problem and you should call up Miller support. Their TIG phone support group is pretty good.

Thanks for the reply. The feature is just not working on the 200DX. I also have 250 syncrowave so I know how it works. Didn't mean to steel other guys post, but exact same issue.

[drichmond]

thank's for the reply's i was hoping it was just me not understanding the new inverter technology and not setting it up cause i have tryed every way i could but no luck. no problem jumping in rdk that's why i havn't posted much because usally someone posts what i need to know. also when dc welding the sound is almost silent is that because the hf is not working i'm so used to syn 351 and linc pro tig that this dynasty is throwing me ques. myself

Lack of noise is one of the advantages of dc tig. The hf will make a little noise but it's only needed for arc start on dc.

I would get to miller tig for help as soon as possible, this was happening a few months ago with the some new D200DX's, a search might bring some more light on the picture.

Still unresolved?

drichmond,

Call Miller at 920-735-4505, choose option 4 and ask the operator for TIG applications. Tell them what is going on with your machine. Let them know it is brand new. An arc starter board is a stock item and it only takes an hour to install it.

There have been some problems with the vendor of the PCB having a bad capacitor on the board. I had the same problem: I used it once and the HF died. No problems since the HF arc starter board was replaced.

If you have problems and cannot get things fixed, email me at [email protected]

It's a minor fix and the new PCBs are working out just fine.

Miller is going to need a S**tpot full of bad cap boards to hold a candle to Dell computer! Dell has spent well over $1,000,000 replacing processor main boards on the GX270 series. Bad caps that bulge and sometimes explode. Heck I had to replace the HV caps in my Gateway 17" flat panel. I think only 1 was bad but 4 were in parallel and it was easier to just replace all 4 than it would have been to isolate the bad one.

I agree with you tailshaft. It can and does happen to every company out there in the market place. I remember 10 years or so ago when TRANE could not make and AC unit without a leaking coil. They got it fixed and on they went. It can happen to the very best.

Thats very true, esp for electronics stuff of any kind. Before I retired I was sometimes buying PC's in very large lots for the place I worked. It didn't seem to matter much who I purchased from or which brand I purchased the failure rate was 10-15% out of the box. It does matter who you purchase from though, and Miller knows what the problem is, knows how to fix it, and most times will get it fixed with little hassle.

Thats pretty funny, were in the middle of this right now at work. Our desktop guy is on the phone almost every day getting new motherboards sent out! We probably have 30-40 of them and they fail constantly. Bad bulging or leaking caps. Wonder if it's the same supplier??
