R.S. Hahn & Sons has two primer computerized plasma cutters. Similar to a laser, our state of the art plasma cutters use electric arcs for high-definition cutting. Unlike a
gas-axe, our plasma cutters work by ionizing the sheet metal rather then oxidizing it. This means that a plasma cutter uses a strong electromagnetic field and applied heat source to weaken the
molecular structure in the sheet metal in a very limited area, and then the cutter needs compressed air to blow that metal out of the gap. The primary advantage of this method is that it will nearly
cut any material, from stainless steel to aluminum. The negative side of a plasma cutter is leaving a rough edge that will need to be filed down for smoothness by the craftsman. This will add to
labor costs of the finished product.
