Are there training classes on how to use tools? Wii-related.

Howdy! I’m new here. I wanted to ask a couple questions about console repair-related stuff as I’ve seen lots of console repair videos and I’m very interested in doing it myself. I’ve previously looked at this site to figure out how to replace disc drives and maybe fix dead AV on my old Wii (it’s the first model from 2006, which I’ve heard is known to run into problems with the video and disc drive). I did end up sending it to someone to have it fixed, but I guess my main question is: are there certain requirements or training procedures for using soldering tools? I know fixing AV trouble involves soldering, and I know there’s a lot of burn risks involved. I’d like advice on where I can learn to to use soldering tools so I can repair stuff beyond just replacing parts and cleaning.
