19654 - ESAB PT-23 / PT-27 Plasma Torch Collet

ESAB 19654 Collet: Technical Overview

The ESAB 19654 Collet is a critical consumable component engineered specifically for the ESAB PT-23 and PT-27 series of plasma cutting torches. As an integral part of the torch's internal assembly, this collet serves the dual purpose of mechanically securing the electrode in place and facilitating the transfer of high-amperage electrical current from the torch body to the consumable stack. Manufactured to ESAB's rigorous Original Equipment Manufacturer (OEM) standards, this part ensures precise concentricity between the electrode and the nozzle, which is paramount for maintaining a focused plasma stream and achieving high-quality cuts.

In industrial plasma cutting applications, the collet is subjected to significant thermal cycling and mechanical stress. Over time, these forces can cause the collet to lose its spring tension or develop surface oxidation, leading to poor electrical contact. A compromised collet can result in erratic arc starting, unstable plasma streams, and premature failure of other consumables due to arcing within the torch head. The ESAB 19654 is fabricated from a high-grade conductive alloy designed to withstand these harsh operating conditions while maintaining excellent electrical conductivity and mechanical resilience.

For procurement specialists and maintenance managers, sourcing genuine ESAB parts like the 19654 collet is essential for protecting the longevity of your capital equipment. The PT-23 and PT-27 torches are legacy systems known for their durability, and maintaining them with authentic components ensures they continue to deliver reliable performance. This collet is compatible with various ESAB power sources that utilize these specific torch models, making it a staple inventory item for shops running older ESAB plasma systems. Proper installation and regular inspection of the collet during consumable changes are recommended to prevent downtime and ensure safety compliance.

By choosing the ESAB 19654, you are investing in the reliability of your cutting operations. Generic aftermarket alternatives often lack the precise dimensional tolerances required for these specific torch heads, potentially leading to gas leakage or coolant flow issues in liquid-cooled variants. Stick with the proven performance of ESAB engineering to keep your production lines moving efficiently.
