What are the pros and cons on these two machines ? If you were purchasing a new unit would buy a 210ext or 250ex ?
I too would like to know that because i have had the 250 ex for awhile and i am thinking about selling it to get the 210 ,have been happy with the performance of the 250 but i am getting to doin alot more aluminum work now and would the features of the 210 just wish it had a little more amps like 250.
I have the 250EX. I don't think I could rationalize the idea of swapping out a 250EX for a 210ext. Except for the goodies that the more recent 210ext might have, I wouldn't trade a equally capable machine that puts out more amperage.
Make sure that you get a machine that fits your needs, your future needs, and the flexibility that you desire. Sure, the machine might do wonderful things like slice bread and butter it at the same time.
Boys, these are tools, not toys. These are designed to do a job. Don't let your emotions make decisions for you!
They are both mean, lean, green machines.
your right about them bein tools for sure and the 250 ex is a good machine and im,in it to make money ,so of jobs i am doing the 210 and the adjustments it has on it would make things a little easier,but the 250 is capable of doing it,just like some the features on the 210.
Which features make you want the 210 over the 250 ? I'm not a professional welder, I'm just curious.Quote:

You got that right,,cannot imagine trading down in amps and having to work through a touch screen to make adjustments, when everything on the 250EX is in plain view on the dials,,,the 250Ex is a hard machine to beat in both performance , useabliltiy, and price,,I like mine and won't be replacing it that's for sure..Quote:

i bought the ex for portability and easy setup for aluminum welding. check the setup for my trailblazer and i still only get 225 amps out of it. i keep the hi freq around just in case. if the ex can't handle it i pull out the spool gun and a plumber's torch. it's no accident that miller is coming out with a 280 dynasty. people have been waiting over a year for it's release, the only reason they are coming out with it is they know they are losing sales.
here's a shot of the ex in action on a boat i have been doing quite a bit of work on. in this case new grip rails.

when the material gets real thick and the tig is too slow; time for the spool gun.

man, that last picture is a product seller; oleg needs to kick me a ball cap or something. lol
not that i want to loose that amps if you read my first response on this thread just like the adjustments the 210 has.but i like my 250ex ,has made me some good money more than paid for itself.never have topped the machine out on duty cycle .Quote:

Just remember guys, I'm not being sexist, but computers are female. I'm sure you ladies out there can say the same about us guys.
I don't believe that the 210EXT offers this feature. Sounds like you are confusing the 250EXT with the 210EXT.Quote:

It does offer the control over the AC balance, which adjusts the positive and negative sides of the arc. It does not offer amplitude control, however.
It also has wave form, which none of our other machines have, as well as the advanced pulse for welding aluminum.
Which is what i am looking for,for those of you who have never used something like this you can make sweeeet lookin aluminum welds with these options.Quote:

Sounds like you have a valid reason to get the 210ext.
The 210EXT doesn't have the asymmetric AC output like the Aerowave, only the 250EXT has that feature.Quote:

The 250EX will do this only after the AC balance potentiometer has been replaced with a 1 meg pot, or that's what it took on the two 250EX's I have. I would put my 250EX up against any high end tig welder!
How did you determine the change of the 1 meg pot would help the tungsten?I dont understand electronics this way at all and would like to learn stuff like this to understand how things like this work and do my own mods without harming the machine.
My first 250EX was bought used, it was owned by a guy who worked on all brands of welders. He said the 250EX was not welding at factory specs, it would not pulse at .2pps and would not weld at 10 percent electrode positive so that's why the change of potentiometers. A local shop explained to me that electrical parts like resistors and capacitors have a tolerance of 0 to 10 percent, only the military can afford the 0 to 1 percent tolerance. After a series of capacitors and resistors at 5 to 7 percent tolerance, the needed resistance in the potentiometer may need to be adjusted.
After buying a new 250EX, it only took a minute to see the difference between the two. The modified 250EX can be adjusted to have no cleaning action and a super focused arc with no arc wandering, tungsten spitting or dingle berries while keeping a super sharp tip at 250 amps on AC. Also a 1 meg pot in the pulser makes it pulse at .2 or one pulse every five seconds, when it was new it would only truly pulse at 1 pps.
Oleg knows all of the mods done to my machines, surely be now the factory has tested them as well. I believe after these modifications, the 250EX is one of the very finest welders available at any cost.

Those welds look mighty fine. It would be nice if you would do a thread about the mods done to the machine.
1 pulse every 5 seconds.... keep heat down or working with anodized AL?
