One Source Equipment Rentals has Miller Spectrum plasma cutters for rent or sale. These units will cut any metal that is electrically conductive including: steel, stainless steel, aluminum, and copper. Softer metals like aluminum, copper, and stainless will derate the cutting depth. So a plasma cutter rated at 7/8″ for mild steel might only rate 3/4″ for aluminum. The process of plasma arc gouging produces less dust, smoke and other harmful environmental hazard as compared to carbon arc gouging. Applications include construction, maintenance/repair, fabrication, and manufacturing.
