I've signed up for a basic tig welding class and have read many of the posts on the "mentor/path" parts of this site. The class will meet five times once per week. I think it will be really interesting. Any suggestions on questions that a beginner should have in their back pocket going into an intro to tig class? (I'm interested in this skill because I've seen how refined it can be - primarily on this site, but others as well).

Thanks,
