19917 - Esab PT-31 Plasma Cutting Nozzle .057 (5-Pack)

Technical Overview of the Esab 19917 Cutting Tip

The Esab 19917 Cutting Tip is a precision-engineered plasma arc consumable designed specifically for the PT-31 and PT-31XL series of plasma cutting torches. This component, often referred to as a nozzle, plays a critical role in the plasma cutting process by constricting the ionized gas stream (plasma) to focus energy density on the workpiece. The 19917 features a specific orifice diameter of .057 inches, which is calibrated to handle the gas flow and amperage requirements typical of the PT-31 system's operational range. Maintaining the correct orifice geometry is essential for achieving clean kerf lines and minimizing dross accumulation.

Manufactured from high-grade copper alloy, the 19917 tip offers excellent thermal conductivity, allowing for efficient heat dissipation during the cutting cycle. This thermal management is vital for preventing premature erosion of the orifice, which can lead to a widened arc, reduced cutting speed, and poor cut quality. As a genuine Esab part, this nozzle ensures dimensional accuracy and compatibility with the electrode and swirl ring assembly within the torch head. The concentricity of the orifice relative to the electrode is strictly maintained to prevent double-arcing and to ensure the plasma jet exits the torch axially.

This product is supplied in a package of five, facilitating routine maintenance schedules in industrial environments. Regular inspection and replacement of the cutting tip are recommended, as a worn orifice will significantly degrade performance. Signs of wear include an out-of-round orifice or excessive spatter buildup on the tip face. By utilizing OEM consumables like the Esab 19917, operators can maintain the factory-specified performance parameters of their plasma cutting equipment, ensuring reliability and safety during operation.
