Wow! You all are a wealth of information. I purchased everything from the stained glass supply store in town, so it should all work together. I only used it for a few minutes, and I wiped it clean with a damp waffle weave towel. Its not dirty. I will try all of your great suggestions on Monday when the kids are back in school. Unfortunately can't play with it while they are home for safety reasons. I'm suspecting something wrong with the heating element in the tool, since its new. At least, I hope.
