As the title says. I have zero experience with welding. Just bought a house and have a large garage for the first time. I'd like to be able to do rust repairs and other general "fooling around with old crappy cars" kind of stuff.

What's the best way to learn well enough to get decent/serviceable results without investing years of time? Do people still start with stick welding, or just go straight to MIG?

For general automotive welding, go with a MIG. A trip to the pawn shops will usually find you a decent MIG machine for a couple of hundred. Hobart and Miller are the preferred brands. The Hobarts will be a good bit cheaper. 

Learning is a case of practice. YouTube videos will help as well but mostly it's lots and lots of practice. You might also consider a welding course at the local tech school.

There is no replacement for years of practice.

However,  Youtube videos, a basic understanding of metallurgy and heat transfer will get you pretty far.  A MIG is a good starting place to learn puddle control and setting up the machine.  Get a cheap welder and some scrap metal to practice running beads and sticking coupons together. Prep your metal before you weld even if that is just hitting it quick with a paddle wheel to get the mill scale off of it. Clean metal is happy metal.  Also while shielding gas can be expensive it offers more repeatable results and personally I find it easier to deal with than flux core wire feed welding.

I've never had an automotive application where stick was required.  MIG is probably the easiest welding process to learn and with today's machines you may never need another process.  I prefer TIG on sheet metal and aluminum and I'll still occasionally gas weld stuff with the oxy-acetylene torch but mostly as a novelty. 

If you're working with crappy old cars in NY you'll probably want an oxy-acetylene setup at some point for removing rusted parts and fasteners but that's harder to learn than TIG and isn't as useful for welding as wide a range of material thicknesses. 

I started with an oxy-acetylene setup, added a MIG and then a TIG that can also do stick and I still use all of them (except the stick capability) on a pretty regular basis.

It might be a good idea to get 220v receptacle installed. Lets you weld thick  pieces easier. My Harbor Freight 170 amp welder was cheap, but it works

Subscribe to his YouTube channel.  Watch all his vids on whatever type of welding you think would be good.  A WEALTH of info there.

For almost everything, I recommend MIG.

My first welder was a TIG, which I love, but I do like the "quick and dirty" convenience of MIG.

I recently picked up an Oxy-Acetylene kit.  I rarely use it, but when I need it, it's very good to have.

I do not use stick welding, I do not like stick welding. Not on a frame, not on a car. I do not like it here or thar. I do not like it anywhar.

I did a "How to replace a sill" thing on Sweedspeed. About halfway down there is a quick "How to MIG weld panels together. Won't make you a welder, but it let you stick metal together good enough to get the job done.

For the cost of a welding class at my local college I bought a Millermatic 211, gas and some scrap metal.  I've built a new stand on wheels for my bandsaw, a welding cabinet/welder/gas bottle holder on wheels and a fancy Tab and slot welding table.  I've even made some other repairs and modifications around the house.  I've watched a lot of youtube videos too.  Miller just came out with a multi process welder that can do AC and DC TIG as well as MIG.  I'd get that if you can swing the asking price.  Otherwise, grab a decent MIG machine and start putting things together.  It's very enjoyable.  It's also potentially a giant black hole that involves a lot of learning and buying accessories.

I took a welding class in college. I don't remember much of the classroom portion, but the "lab" work was "here, kid, take this 3x3x1/8 inch plate. Lay beads across it right next to each other. Fill it up, turn it 90 degrees and do it again. Come see me when its an inch thick."

Was tedious, but made for what must have been about 20 yards of practice beads. Get a cheap used MIG and practice.
