The ESAB 20759 is a heavy-duty copper alloy nozzle retaining cup designed for the PT-15XL mechanized plasma torch. It is engineered for use with Nitrogen (N2) or Argon/Hydrogen (Ar/H2) gas mixtures, primarily for cutting stainless steel and aluminum. The component secures the nozzle and electrode assembly while shaping the shielding gas flow to ensure arc constriction and thermal protection during high-duty-cycle industrial operations.
Features
Mechanically secures the nozzle and electrode assembly within the torch head
Shapes shielding gas flow around the plasma arc
Calibrated for the thermal and fluid dynamic properties of Nitrogen and Argon/Hydrogen mixtures
Geometry facilitates gas curtain cooling of the nozzle bore
Constricts the plasma arc for maximum energy density
Manufactured to tight tolerances to ensure concentricity between nozzle and cup
High dielectric strength to prevent electrical breakdown
Thermal resistance against radiant heat from the workpiece and plasma plume
Resists carbon tracking and deformation in high-duty-cycle environments
Maintains straight cut kerf and prevents beveling
