i just finished taking the hot works safety class and i have prior experience in welding.
That would be up to @Team_Metal_Shop. I could sign you off for MIG, but that’d be it for me.
Basically you find a time with an instructor to do a quick checkout.
We bring out some scrap steel, and only tell you things specific to our machines (like how the manifold is setup since we use bulk gas rather than individual tanks).
@dryad2b can do MIG with you. I may have an opening this week to do a TIG or Stick sign off in an evening.
