Finally got the plasma cutter that I've been wanting. The local welding supply had a great deal on CutMasters and I got a Cut Master 50 with a 1 Torch and a air drier. Is there a trick to to using the torch? One mild steel I can get great results on just about any thickness within the rated capacity.. However, I had a 10 x
20 flat panel metal shed to take down and it didnt seem to cut worth a hoot (mostly rust with some paint). Towards the end, I ran the tip as fast as I could across 5 feet of wall and it was like Star Wars, There was a very fine clean cut. It was difficult to repeat this trick. PSI was set at 75 and amps at 35. Advice appreciated.Also, I saw an ad in one of the fab magazines about a book titled: "Forty Years Secrets of Welding for teh Hobbiest or Professional" by Earl Durfee. Is it worthwhile?? regards, Jim
