Try your local Community collage or trade school. If there is not one close then go to your high school and ask their shop teacher for some advice!:thumbsup:
These videos are a pretty good start. You can buy them online or at Northern Tool. Maybe other places too. A pretty solid view of the puddle and discussion on the most common basics. Instructional Welding Videos

I took welding at a tech school and the course was sufficient for a good student to be able to test as a certified welder if they wanted to.
My instructor was a welding engineer that had welded pipeline over the years, taught it and wrote books on the subject.
He knew his stuff and had us welding--or trying to--20 minutes after the class started.
It I wanted to weld for a living I would call the tech line at Lincoln for starters and then search the net plus ask a lot of questions from those who know how to weld correctly.
