Well.......I can only speak from the MIG side since that's all I use. It sounds like you are getting a really fine machine. For what it sounds like you are going to be doing, I can't imagine the duty cycle being a problem. If you are planning on using the gas co2/argon mixture, you will get beautiful welds! (Flux-cored wire isn't as pretty.) You might want to have both machines eventually anyway so I can't imagine anyone who is into working with metal not getting their money's worth out of a mig machine. Just my thoughts although response from others who also do TIG might be more helpful.
