Need help w/ Dial Arc 250 HF-P Aluminum setup

admin

I have a Dialarc 250 HF-P, with the Mic 4 inverter, and a tig torch with thumbslide, I've been using it to stick weld and it runs fine, but I'd like to try and weld  aluminum tig with it, nothing major , just practice and play with it, I work at a local marina and there is demand for aluminum repair, just small stuff, any advice would be greatly appreciated, thanks.
