When I cut out forms in light gauge steel with a plasma cutter, I am having problems. I trace the patern out with a pencil. When the pattern is traced out with something like a sharp nail, it cuts OK. Could the graphit in the pencil trace conduct better than the steel, causing the problems? Tnx, Title: Re: Plasma Cutter Post by: KM1H on December 18, 2010, 10:43:15 AM Use a Sharpie
