Hello,
I have had my 250EX just over a year now and love it. I had forgotten to swap the wires like an idiot after they told me they had them labeled wrong. Smart thing for a former electrician to do, lol. Wasnt that big of a deal being you gotta wire the plug up yourself anyways. Other then that everything seams to be perfect on it. I know nothing about tig other then what I have tought myself. Everything that I have seen, it seams to work great. I love all the analog knobs and love the amperage adjustment being an analog knob with a digital display. All the feutures on it are great. Like I said, I am no expert and just learning on the thing. However, everything that I have researched it is working great. I also like that if I had to I could run it at less amps with 120. That might come in handy some day.
Thanks,
Tesla
