Start off with MIG and steel. You can practice with fluxcore wire instead of wasting argon while you are learning. Aluminum, and stainless requires TIG welding and takes alot of time, and practice to get the hang of it.
welding aluminum and stainless does not require a tig. You can weld them both with mig. just have to get different wire and gas.
