I heard you can dial down the start amps to 10 or so...which is fine as long as it fires up fast and holds really a steady arc so I can start moving. I just received a 250ex in the mail that had some shipping damage and going to send it back. Me and Oleg talked about the 210ext and I think it is a good idea. I would love to have a machine that can weld razor blades, but still have the power to weld 1/4 aluminum. All while having a super stable arc. One last question....how does the solid state capacitor ignition compare to the points?......sorry for all the questions thanks - RJ
No problem on the questions. Unfortunately, I can't answer on machine performace as mine was sent from Amazon, and they screwed up and sent me a defective unit that was previously returned. i spoke with Oleg, and he is replacing it directly with a 2013 model, so I am in wait mode. Mine powered up, but would not provide any current. I had played with a Lincoln Invertec 205 AC/DC machine, and this is a pretty close clone. I looked at the Dynasty 200DX, but never had hands on. Either way, for the price, there is NO comparison, as I am not getting paid for my welding, if it were my major income, I could probably jsutify the name brands, but I doubt I would ever get to their CEO if I needed help.
Bottom line, if you want to weld delicate materials, with fine precision, this is a better unit for you then the EX (IMHO), The key difference is the ability to select waveforms (Square, sine, modified sine/triangular). This is good for thinner aluminum, the waveforms only work in AC mode, but for Moly tubing, you can dial down the power to 10amps and still pulse it for more control. The duty cycle is 35% vs 60% for the EX machines, but they make a LOT more noise and are less portable, and that is only at Rated (full) power. For my uses, I get 100% duty cycle at about 100-120 amps. Also, the 250EX has the most control of the EX series, and comes with a water cooled torch, requiring the $379 cooler, and further adding to noise and lack of portability. you could get a gas cooled torch good up to 200 amps. Bottom line, for what you are looking for, sounds like the 210EXT is fine (I assume you meant .035 vs .35 thick wall). I will be using it for aluminum fabrication of under 1/4" thick material. I have a MIG with Spoolgun for thicker and bigger projects.
