Will im sorry you are leaving. Itried to give as much help on the welder as I could without seeing it. I would have even called you to talk about the welder if you had ask.I enjoyed your post. Sometimes if no one has any experience with the zd323 or the rtv900 they may be like me and afraid they may direct you in the wrong direction. I still would mount the welder on a inexpensive platform and test it to see if it works it would make you a good welder if it works ok. Sorry if I let you down on this I will still be glad to call you and talk to you about the welder on phone if you wish. Good Luck handy
