We let off a few sparks here at UCEC from time to time. Sometimes, sparks fly because we're grinding off existing studs on the back of a door that are in the way of a device. If a project requires it, we can weld stainless steel, steel or aluminum. We can also plasma cut stainless steel, although our Steinhauer MC-80 does most of our stainless work these days.
Enjoy a few sparks!
