Tim if there is a local school where you could take a class that would be very good. with some of the new inverter machines they are relatively inexpensive to get started. if your serious make investment into a MIG machine, self darkening hood and a tank of shielding gas, and a roll of mig wire. might look on marketplace for a used machine too. Yes, I know there are tons of people that will tell you to just use flux cored wire. well with shielding gas you will get much better results. Amperage of machine you need is determined by thickness of material you plan on welding. if your wanting to weld aluminum you will need additional gear or a TIG set up. There are tons of videos on YouTube that teach welding. Or you could just get a stick welding machine/buzz box and some welding rods like 6011 is an all-around easy to use rod for steel that uses AC output power.
