not trying to start an argument, I'm simply saying that for the novice hobby welder who wants to stick some metal together but doesn't know where to start you can find someone to teach you or you can go take a half a day class. Yes I get it the reason is so you can try out equipment and maybe buy something but you can also get just enough basic info to gain just enough confidence to go back to your garage and stick some metal together. Its like anything else, you need seat time weather you're a pro or a hobbyist. Most people also need just enough info to confidently try it on their own any maybe just maybe 50 bucks and 4 hours on a Saturday would give them that
One might learn enough to decide to take a full semester class at a junior college, or maybe they don't want to.
