OK... for starters your Oxy-acetylene torch gives you the ability to cut all sizes of steel if you have the right tips. It also gives you the opportunity to forge, weld thin metal and braze.
The ability to gas weld is the same skill required to TIG (tungsten inert gas) weld metal. The big difference being TIG supplies instant heat with it's arc where you are welding as well as the ability to weld any metal you have filler rod to match. Stainless, brass, bronze and aluminum can all be TIGed, also known as heli-arc.
Your torch can weld thin mild steel easily, the process is just slower than TIG and transfers a lot more heat. When you weld you're fusing the metals together. The torch will also allow you to braze steel, which doesn't fuse the steel but joins it with brass instead and requires less heat since only the brass melts. Brazing is a very handy skill and will let you join (and repair) all sorts of things with just a torch, brass rod and some flux.
The MIG (metallic inert gas) or wire welder is handy and pretty easy to learn, but a cheap MIG won't weld thick or dirty metal like arc welding does. A MIG --like TIG-- will also weld any type of metal that you have wire to match.
If you're in school maybe there is a class offered there (industrial arts or sculpture) that can introduce you to the processes and get you started. Where I live there is an art center with welding classes and students of all ages & backgrounds have learned to weld there.
