Timothy,
I can tell you that mig is by far the easiest process to learn; and it will cover most of what us 'home gamers' need to weld. There are two types of mig welding. Both use shield gas. The difference is traditional mig uses a cylinder of gas that flows through the 'gun'. The other is the same wire feed process (same machine) but uses wire that has the flux inside the wire that burns to create a shield of gas as the wire burns. There are some subtle differences but mostly the same except for the wire.
The only thing you need to 'learn' other than basic safety, is the balance between heat and wire speed. Too much heat and the base metals burn through or undercut. Bad welds. Heat too low and you get a surface weld that is not strong. Heat will also effect your wire speed. Too hot and the wire burns before it deposits in the weld. Too slow and it clumps on the surface. There is a learning curve like anythings else. The good news is one can pick it up by laying a few beads and letting the metal tell you what it needs. Mig is super simple after the first few beads. Youtube and online groups really can teach you everything you need to know for garage welding.
Get a decent hood. You only get one set of eyes. Don't underestimate how long a spark can sit under something combustible (cardboard, rags, chemicals) before starting a fire. Keep a fire watch for at least a half hour after working if you are not in a cleared area. Invest in a fire extinguisher. You may never need it...until you do. The good news is mig is not as messy as stick welding, but you will be using a grinder and that can shower an area with sparks and hot metal. Don't grind or weld on galvanized or other coated material without a respirator.
Import welder have become silly cheap in the past 10 years. Everlast is a good import brand. One can get caught up in the Miller/Hobart - taste great less filling debate. The differences between the brands are subtle enough to be lost on a garage mechanic. Save your money for consumables. Most of all enjoy your new skill.
