Guess I should have read the manual. I just watched the panel video you did and did not need anything else (so I thought). If DC has 1-9 and AC does too, that is overkill for me But cool...
So other than not having the quick connect for the argon (in my case; using a hose clamp with no problems) and the larger 26 torch, I will still give the 210EXT an A+ "so far". "So far" means we did stainless yesterday and today (and got paid today ), but I have not done aluminum with it.. The only thing left to test otherwise I'm in love.
I went out to check the presets, they are 1-9, so only 9 settings. And it looks like the AC/DC you have to note it is not saved like I thought, but Mark will make sure.
What's funny when I went to check the presets, my younger son had used it today. The 210EXT had a cover on it (he does not cover welders, Dad does). So I think he might like it too. I know the pulsing downslope and the CD start he liked a lot.
