I'm not sure how well those'll work; I haven't had very good luck. (I tried arc gouging with a "graphite" pencil as an electrode, and the tip of the thing just sort of exploded as soon as I struck an arc.) I think I'd be more inclined to try purpose-made gouging electrodes from a welding supply store. Pencil leads contain a lot of clay. I’m not sure how well those’ll work; I haven’t had very good luck.

Iron wire can be purchased at any Home Depot, and can be dipped in enamel to minimize losses due to eddy currents. Pencil leads or carbon rods from carbon electrical cells can be used.

The word "goggles" doesn't cover what is required here for safety. A full face shield with the darkest lens available, and every inch of skin covereed on your entire body. The comments are well put.
