Todd B. - Great to hear from you again!  You really are breaking your silence.  That unit does look nice and I the more I review video from the inter-web stick welding seems archaic compared to TIG.  You and everyone else are swaying me in that direction.  Yes, I always figured I could eventually lean the skills to do a reasonable weld (as opposed to playing an instrument or singing at a profession level)  but given that it took me the more than a decade of 60-100 hr weeks to become a physician I was wondering if welding could be done with a little less commitment.  ;-)    Is your plane still flyable?   I am in the midst of an engine re-build and tear-down inspection that looks like it could use some welding.
