0004470045 - ESAB PT-36/600/19XLS Nozzle Retaining Cup

Precision Engineering for High-Performance Plasma Cutting

The ESAB Nozzle Retaining Cup (SKU: 0004470045) is a critical component designed specifically for the high-precision requirements of the PT-36, PT-600, and PT-19XLS plasma torch systems. In the realm of automated and mechanized plasma cutting, the alignment of the consumable stack—specifically the electrode and nozzle—is paramount to achieving the tight tolerances and vertical cut edges these torches are known for. This retaining cup serves as the primary mechanical interface that secures the nozzle in place, ensuring concentricity with the electrode and the swirl ring.

Manufactured in the United States to ESAB's exacting OEM specifications, this retaining cup is built to withstand the extreme thermal cycles and dielectric stresses inherent in high-amperage plasma cutting. The material composition is selected to resist thermal deformation, which is a common cause of premature nozzle failure and poor cut quality in aftermarket alternatives. By maintaining a rigid and precise hold on the nozzle, the cup facilitates the correct velocity and distribution of the plasma gas, directly influencing the constriction of the arc and the energy density delivered to the workpiece.

For industrial MRO professionals managing automated cutting tables, using genuine ESAB parts like the 0004470045 retaining cup is a strategic choice to protect the longevity of the torch head itself. A compromised or ill-fitting cup can lead to gas leakage, internal arcing, and catastrophic damage to the torch body. This component is engineered to provide a secure seal and robust protection, ensuring that your PT-36 or PT-600 system operates at peak efficiency with minimal unplanned maintenance intervals.
