Where can I learn hobbyist welding?

Look at your nearby colleges to see which ones have trade schools. Some of these offer continuing education classes on evenings and weekends. I've done several in Ottawa at Algonquin College (small engine repair, etc.) and I recall they offer welding as well. Classes are 3hrs a week for 10-12 weeks and cost me around $300-$400.

Try youtube.

Your best bet is trade schools.

If you are not going to do any structural welding or trailers etc, just buy a quality 240V mig welder. If you can run a bead of silicone, you can mig weld, its really that easy.
I started welding when I was 17 and worked in factories for 7 years before I decided to change careers. Do your health a favor and buy a high quality 3M respirator and welding filters.
Don't buy a 120V mig welder. Buy a 240V model and get an argon gas bottle to get that smooth weld you will be looking for. Also if you are going to mig stainless steel, you will need to buy stainless steel wire.
Welding ease of use by type:
Mig = easiest (240V machine will weld 3/8" steel no problem)
Stick = small learning curve (strongest welds)
Tig = hardest to learn (best looking welds)

You can accomplish what you are wanting to do with a 120V mig but if you really get into welding, I can guarantee that you will want to use it for other things. 240V is the way to go.
Dont forget the respirator!

You can also look into oxy/acetylene welding. I bought myself a torch and two tanks and by looking at YouTube tutorials and practicing on scrap pieces I can do some pretty decent welds now. It's also one of the most economical set ups, I got mine for $200 cash from Kijiji.

I think Toronto district school board used to have a continuing ed night course called something like “art metal working” where they teach welding to make things like plant stands, etc

I know a guy that's moving who is giving up his 220v miller stick. Older machine but runs well, might be a good fit for your needs.

Agree if you get mig it needs to be 220, not as easy to set up in your garage but building good sized bbq's and frames isn't going to be lightweight work.
