Depending on your location, you may have a local makerspace, tool library, or similar; oftentimes places like that will have beginner classes on the cheap. Granted, that may all be on hold presently for Covid-19, but could be a nice thing to bookmark for later.

Edit: as an example from my own locale, the Denver (Colorado, USA) Tool Library typically has a beginner's welding class for $150: https://denvertoollibrary.org/upcoming/welding-101-fjbkt-k4g..., though they've suspended all in-person classes while the pandemic rages.
