AC welding setup

[ALO604]

I have just received my 200DX.
Never welded with AC before, only DC steel. Do I need to switch cables around or does the machine take care of polarity when switching it to AC mode aluminum?
I realize that settings play a role in weld quality,,,,I'll get to that.

No. The torch stays in the negative for all TIG operation. Download your manual from the website. It is up on it. It covers pretty much everything as far as setup. https://www.everlastgenerators.com/s...0d9a4d89b3.pdf
