20386 - ESAB PT-121 70A Plasma Gouging Nozzle

Precision Plasma Gouging with ESAB 20386

The ESAB 20386 Gouging Tip is a specialized consumable component engineered for the PT-121 plasma cutting torch system. Designed to operate at 70 Amperes, this tip transforms a standard plasma cutting setup into a highly efficient gouging tool. Unlike cutting tips which focus the plasma arc into a tight, severing stream, this gouging tip is manufactured with specific internal geometry that broadens the arc. This allows the operator to wash away molten metal effectively, creating smooth, clean grooves for weld removal, defect correction, or edge preparation.

Manufactured to ESAB's rigorous OEM standards, the 20386 tip ensures seamless compatibility with the PT-121 torch head. The use of high-grade copper alloys provides excellent thermal conductivity, which is critical for maintaining tip life under the intense heat of the gouging process. Proper heat dissipation prevents premature erosion of the orifice, ensuring that the arc characteristics remain consistent over the life of the part. This consistency is vital for automated or manual operations where depth control is paramount.

In industrial MRO environments, plasma gouging is often preferred over air carbon arc gouging due to its reduced noise, lower fume generation, and the lack of carbon contamination in the base metal. The ESAB 20386 facilitates this cleaner process, leaving a bright, metallic surface that often requires little to no secondary grinding before re-welding. This efficiency translates directly to reduced labor costs and faster turnaround times on repair projects.

Installation is straightforward, following the standard consumable stack-up for the PT-121 torch. Users should verify that their power source is set to the appropriate amperage (70A) and that the gas pressure is adjusted for gouging operations to ensure optimal performance and safety. Whether used for removing temporary attachments, back-gouging root passes, or repairing cracks in heavy equipment, this genuine ESAB part delivers the reliability professional fabricators demand.
