New Miller Syncrowave 250DX

Hello - Our shop inherited a Miller Syncrowave 250DX (air cooled) and we are new to TIG welding, but are experienced stick, mig...etc. We have read the manuals and a lot of general stuff from Miller, but we wanted to hear from experienced welders about general setup. Can someone let us know what is a good machine setup for practicing beads on 1/8" Aluminum plate? We have 100% Argon. Not sure what amperage or tungsten would be best to get our feet wet. Also, I assume that the "AC" setting is what we should be set at on the machine. Thanks for any and all advice!
Yes, AC. I would put in a 1/8th tungsten. 70% balance(30% cleaning), just enough post flow to keep the tungsten brite, #7 cup at 18cfh.
