20387 - ESAB PT-121 100A Plasma Gouging Nozzle

Technical Overview of the ESAB 20387 Gouging Tip

The ESAB 20387 is a specialized plasma arc gouging tip engineered specifically for the PT-121 plasma torch platform. Designed to operate at 100 Amperes, this consumable is critical for industrial applications requiring the rapid and precise removal of metal. Unlike standard cutting tips which are designed to constrict the arc into a high-velocity jet for severing material, this gouging tip features a modified orifice geometry. This design broadens the plasma arc, allowing it to wash away molten metal effectively rather than piercing through it, making it ideal for back-gouging welds, removing defects, or preparing plate edges.

Manufactured to ESAB's stringent OEM specifications, the 20387 tip is constructed from high-conductivity copper alloy. This material choice is essential for managing the intense thermal loads generated during 100A plasma operations. The tip ensures optimal electrical transfer from the electrode to the arc and maintains structural integrity under high heat. Proper alignment and seating within the PT-121 torch head are guaranteed, ensuring that gas flow dynamics—specifically the swirling action of the plasma gas—are maintained for arc stability. This component is integral to the thermal management system of the torch, working in conjunction with the electrode and heat shield to dissipate heat and prolong the duty cycle of the equipment.

In industrial MRO settings, the reliability of plasma consumables directly impacts downtime and process efficiency. The ESAB 20387 provides consistent performance parameters, ensuring that operators can predict gouging rates and groove profiles accurately. It is compatible with standard PT-121 torch setups and requires no special adapters, functioning seamlessly with the existing gas distribution and retaining mechanisms of the torch assembly.
