Hypertherm Powermax 30 Electrode #220478
These Hypertherm Powermax 30 plasma cutter electrodes #220478 carry a negative charge. Even during normal plasma cutting, the plasma cutter electrode element is hit with a huge surge every time an arc is produced. It goes almost instantly from cold to an extremely hot. When powered, touching your Hypertherm Powermax 30 plasma cutter’s nozzle to metal completes the circuit, causing an intense spark and heating the gas until it becomes plasma. The plasma gas blasts past the electrode. The charged particles in the gas pull atoms off the hot electrode surface. This normal activity wears away at the emitting element, causing pits on the surface. If electrodes aren’t changed when needed, the torch could be seriously damaged. The electrode can even burst within the torch. How often you use the torch is more important than how long you spend actually cutting. Frequent use usually causes worn electrode elements. You should check the pit in the electrode element often. Hypertherm Powermax 30 Electrode #220478 assures peak effectiveness and durability. This 5 pack of electrodes from Welder Supply is specially engineered for the Hypertherm Powermax 30. View our other plasma cutter consumables.
