I took a couple welding classes last year through the local adult continuing education program here. I don't think it cost me $300 total for the two semesters. Ironically, it would have been cheaper had I NOT been a HS graduate, but that's another story. /forums/images/graemlins/crazy.gif
While I agree that MIG is the way to go for most of us with most projects, I'll tell you that learning ARC first was the best thing I ever did. Now I'd like to tell you that I did this all on my own, but the reality is that I was not allowed to enroll in the MIG class until I had completed the ARC class. The logic behind that is very sound in that ARC welding really shows you how to weld properly and why you do what you do when welding.
After my semester of ARC welding I could get a good, strong weld with an appearance nice enough that I wasn't ashamed to admit was my work. It took a lot of time and practice to get them not only strong but looking good. With ARC welding you can get a strong weld that's ugly or nice but if you get a nice one you know it's a strong one.
On my first day in the MIG welding class the instructor (who'd taught me ARC the prior semester) took me into a booth and ran a gorgeous MIG weld bead on an interior 90 degree corner for a few inches and, after we lifted our helmets, held it up and asked me what I thought.
I was, of course, just amazed at the look and consistency of the weld, the speed with which he ran it and with the lack of slag and spatter common with ARC welds. It looked like a perfect caulk line. I was thoroughly impressed. He then lifted it up and slammed it down on the table and the pieces flew apart. "That's your first lesson," he said. "ALL MIG welds LOOK good. You need to learn how to make them as good as they look." The rest of th semester was spent doing just that. /forums/images/graemlins/smile.gif
Now that I've done it, I would heartily recommend taking the ARC class before MIG even if it's not required. I can't imagine learning how to weld with a MIG setup without that background. /forums/images/graemlins/confused.gif
Good luck with whatever you decide. I hope this helps. /forums/images/graemlins/smile.gif
