Thanks for all the good words guys I appreciate it!
I firmly believe in buying from one of the big welder manufactures like Miller, Loncoln, or Hobart. A good budget machine for a do-it-yourself guy like you would be a Hobart Handler 187. Its got a lot of the same features at the comparable lincoln or miller without quite as high price and for a home garage if well taken care of it'll last you a life time. Plus consumables are available at tractor supply and northern tool. Thats a good thing to have for a weekend warior considering a lot of welding supply houses aren't open on weekends.
I've been welding since I was 14. (I'm 29 now) I was in high school working for a small misc. steel shop doing handrails and what not. I learned on stick welder which I feel is the best way to learn because it teaches the true fundamentals about melting two pieces of metal together. Unfortunately I was never able to take any classes and I really regret it. There are so many little things that a class will teach you about making a sound weld that you'll never really learn without years of experience. About 5 years ago I was young and though I new pretty much everything I could know about welding. Then one day I saw someting I welded fail and it was a real eye opener. At that point I realized that peoples lives relied on my welds and I needed to go back to the drawing board.
www.weldingweb.com is a great place to pick up useful information. It helped me a lot.
Everyone has their own style or technique and you will hear a thousand different opinions, not all are bad. For example, a month or so ago I was down at Carolina Truggies picking up some parts and Alex and I were shooting the crap about welding. We fired up his machine and each layed a few beads. In just a few minutes I saw him do things much different than I do but we both got almost the same result. Shadowing a professional welder is also an excellent way to learn and with time you'll get an idea of what info people give you is good and whats not so good. I still try to look over the shoulder of a welder any chance I get.
I see you're in Harrisburg. My shop is right on 49 at the intersection of Pharr Mill Rd. You should stop by one day and say hey. Maybe you'll catch me on a light day so we can spend a little time going over some stuff. I do offer classes but the shop's been so busy lately I haven't had time to get material together to do it. With all the interest lately I guess it's about time to do one again. I do the classes for 20.00 and hour, usually around 3 hour classes. I supply the welder and all the scrap metal your heart desires and if you get your own machine I'll be glad to spend some time with you dialing it in and getting you comfortable with how it works if you'd like. Let me know if I can help!
