Yes I have it, welds aluminum easy on AC mode. I use it for TIG on chrome-moly, aluminum, stainless, etc, really like it for the price. Only thing is I don't use the MIG feature much because for MIG it uses a spool gun (works great with thick aluminum), but I don't care, I use my 211 for MIG anyway. And I've never used the stick feature either because why would I with MIG and TIG already setup. It's an inverter machine too so its pretty light and only requires 30A service. Although it has its own cart and tank holder so its not really made to be super portable, more of a shop welder for a lot cheaper than a Dynasty. And its made in Appleton, WI.
