Hypertherm Powermax 45 Nozzle #220671
The Hypertherm Powermax 45 Nozzle #220671 from Welder Supply directs the stream of plasma for more precise cutting. When a plasma cutter nozzle and powered electrode touch metal, the spark heats the gas into plasma. The precisely engineered nozzle directs the arc of plasma to a specific diameter. The arc never actually touches the nozzle because the plasma gas provides a thin boundary layer of cool gas. This maintains separation. Problems occur when the current level is too high or low. In such cases, the arc can contact the cutting nozzle and cause a double arc. This damages the nozzle by increasing its diameter. Also, the nozzle could be gouged or the hole out of round. Damaged nozzles should be replaced or there can be a poorly focused arc, causing a bad cut finish. Gouges inside the nozzle are usually caused by current being too strong or air flow too weak. Piercing or cutting too fast can also cause nozzle damage. Your Powermax 45 plasma cutter is a big investment, vital to your productivity. Keep it going strong with the Hypertherm Powermax 45 Nozzle #220671 from Welder Supply. These nozzles are a great value, offered in packs of five. Our Hypertherm Powermax 45 consumables kit and other plasma cutter consumable parts are guaranteed to keep your plasma cutter functioning properly.
