Inherited a little flux core welder a while ago if you know of any good books or videos please share. Had a stick welder years ago but never got a feel for working on thin stuff, I’m guessing this will be the opposite problem.
I het the general theory looking for like practice drills and how to read a weld to know what wrong
I took an introduction to welding class at my local community college. We did oxyacetylene cutting and welding, stick, TIG, and MIG as well as some gouging. It was just a taste of each but it was a good intro.
