Hypertherm Powermax 85/105 Nozzle 85A #220816
The Hypertherm Powermax 85 and Hypertherm Powermax 105 Nozzle #220816 from Welder Supply directs the flow of plasma for precise cutting. When a powered electrode and plasma cutter nozzle touch metal, it creates a spark to heat the gas into plasma. The orifice in the nozzle constricts the arc to a specific diameter. The arc does not actually touch the nozzle. The plasma gas provides a thin boundary layer of cool gas, separating the arc and nozzle. If the current level is too high or gas flow too low, the arc may contact the cutting nozzle causing a double arc. This will damage the nozzle, increasing its diameter. The nozzle must be checked frequently and, if needed, corrected or you could have a poorly focused arc. This will cause a bad cut finish. If a nozzle is gouged or if the hole is out of round, it should be replaced. Piercing or cutting too fast can also damage the nozzle. A worn nozzle will cause cut quality to deteriorate. Your Powermax 85 or Powermax 105 plasma cutter is a huge investment. Protect it with the Hypertherm Powermax 85/105 Nozzle 85A Part #220816 from Welder Supply. These nozzles are a great value, offered in packs of five. Check out the other plasma cutter consumables for the Hypertherm Powermax 85/105 Welders Supply offers.
