Anyone ever take a welding class? Preferably in South Jersey (near Philly area). I recently got an AC/DC arc welder and an oxy-acetyelene torch set. I've played around with the arc and get use it a little bit. The oxy-ace I haven't even tried yet. I'd like to get some professional instruction on how to use these and see people recommend taking classes. I'm just a hobbiest and will play around with welding once in a while on the weekends. I'm not looking for any type of certification, just some good general professional knowledge first hand. Any advice?
