So I bought a new lincoln square wave 200 for home and some small projects. I have only made a few welds but so far I'm impressed. I wanted it for mostly aluminum and anodized aluminum. I think once I get the settings dialed in it will do a good job in the anodized stuff.
Have same and works great in all setups including stick have not attempted DCEN stick yet. But TIG on SS and Aluminum and ferrous metals is very nice unit. Enjoy the pulse and AC balance options.
