Dragon Plasma Cutter Plasma cutting is the process of cutting through electrically conductive, like steel, with an accelerated jet of ho t plasma. The basic plasma cutting process involves creating an electrical channel of superheated, electrically ionized gas through the work piece to be cut, thus forming a completed electric circuit back to the plasma cutter through a grounding clamp. This is accomplished by a compressed gas (oxygen, air, and others depending on material being cut) which is blown through a focused nozzle at high speed toward the work piece. An electrical arc is then formed within the gas, between an electrode near or integrated into the gas nozzle and the work piece itself. The electrical arc ionizes some of the gas, thereby creating an electrically conductive channel of plasma. As electricity from the cutter torch travels down this plasma it delivers sufficient heat to melt through the work piece. At the same tim...
