So... Any good resources for someone who wants to learn how to weld?

no experience whatsoever except i used an oxyacetylene torch and a spot welder a couple times in a shop class ages ago. long enough ago that i don't really remember wtf i was doing.

i don't have a shop or a welder so i would prefer to read / watch courses and get a decent grasp of the basics before i commit to investing cash monies. and recommends for someone just starting out would be appreciated too... particually how you deal w the heat if you are a big wuss about having a/c like me (mostly its cz i have some bad skin probs that flare up in high heat)
