I currently have a bobcat 225, Which i have been told(on this forum) can run a dynasty 200, I also have a super 32 suitcase wire feeder(voltage sensing). And an hf251d high freq box. My question is - in order to facilitate my mobile welding rig for portable tig, should I buy a dynasty or a trailblazer302g. No money right now for a pro 300. I think that I should get the dynasty and then save for a pro300 or something else. my main concern is a/c tig for aluminum.

I'm not a really big fan of running a static welder off a generator because they put out dirty power. If I really had to do it this way, I'd make **** sure I stuck line filters/caps off the incomming power back to a potential chassis ground especially with inverter based units.

Have you considered getting the HF 251 hi-freq arc starter?? It would give you ac TIG at least. Not as good as a inverter based arc, but at least useable..?..Don

the problem with the bobcat and tig is the inability to remotely control the current. Also the a/c tig arc is about as stable as a ducati at 120 with a bent wheel with the quality of a 99 cent angle grinder. D/c tig isnt bad again no remote current control(nice for stainless and sheetmetal). I like the mig capabilities of the bobcat though and the arc is smooth and consistant.Trailblazer 302g

dyn88,
I have always run the Dynasty 200DX from a Trailblazer for mobile TIG. I have seen no problems in a year of operating this setup. I will not be able to give you a long running comparison as I sold both the TB301G and the Dynasty 200DX.
Cruizer has a point about dirty power, but I also ran a Maxstar 200DX from a Bluestar 180 and never had a problem with the Maxstar. It gave me 198 amps of TIG and 168 amps of STICK output.
The Bobcat 8500 watt generator is a big step up from the Bluestar 180 and should be clean enough to run the Dynasty 200 or even a 625 plasma without damage. MILLER ENGINE DRIVE APPLICATIONS CAN GIVE YOU A DEFINITE ANSWER. 1-800-4AMILLER. Dial and ask for engine drive applications.
I do agree with your thinking: Get the D200DX and save for the bigger engine drive. I do know first hand the Bobcat AC TIG arc is sloppy at best.
