I don't think a class is necessary, although I spent months struggling to weld with a crappy stick welder before stepping up and buying a used Lincoln Promig 130 for $300. It's really just point and shoot. I've only used flux core so far and I've welded structural and sheet metal, seems to work fine, although sheet metal is probably easier with gas and produces a better looking weld.

Beginners almost always don't use enough heat, their welds tend to be shallow and lack penetration. There are lots of other things that you will learn in a basic welding class that will make things much easier (fitment, multi-pass welding, out-of-position welding, the 'best' type of welding technique for the job at hand, ect) that are pretty hard to pick-up by trial-and-error.

Good info here, videos are decent also. Buy a welder within your budget, and get going! Definetly get an auto darkening helmet, makes learning very very easy. Spend less then $100 on one, but more then the $50 cheapy at harbor freight (That one WILL! let you down...) ~Nate

Yeah, don't cheap out on an auto darkener. No sense going blind for a few dollars.
Personally, I use the regular helmet. A quick nod drops it in place. I might get an auto darkener for tig welding though, the lift arc start is difficult when you can't see how close you are to the metal.

Auto dark comes in handy when you are under a car.

It's handy everywhere. Not having to blindly strike that first arc is nice, it's very easy to loose your spot.
FWIW, even the cheap ones fail to their darkest shade when the battery goes. ~Nate

Definitely. Just because the weld looks good from the surface doesn't mean that it penetrated enough to be strong. That's where the skill comes in - to apply enough heat to get proper penetration without blowing a hole in the metal.

Good comments fellas - thanks. My dad is a seasoned welder (30 yrs) so he can give me some pointers once I get going - although he's very good at welding he's not good in teaching... so I may take a class anyway, and learn the basics, the terminology and work on my technique.
