KP4752-532 - Lincoln KP4752-532 5/32" TIG Collet Body (2-Pack) for 17/18/26 Torches

Precision TIG Components for Professional Fabrication

The Lincoln Electric Caliber™ TIG Collet Body (SKU: KP4752-532) is a critical consumable component engineered for high-performance Gas Tungsten Arc Welding (GTAW). Designed to accommodate 5/32-inch (4.0mm) tungsten electrodes, this collet body is manufactured to exacting tolerances, ensuring a precise fit within standard 17, 18, and 26 series TIG torches. As a direct replacement for the legacy part number KP2032-6B1, the Caliber™ series represents Lincoln Electric's commitment to updated manufacturing standards and improved consumable longevity.

Constructed from high-grade copper alloy, the KP4752-532 offers superior thermal and electrical conductivity. In the TIG welding process, the collet body performs two essential functions: it transfers the welding current from the torch head to the collet (and subsequently to the tungsten electrode), and it helps shape the flow of shielding gas around the electrode. A compromised or poorly machined collet body can lead to resistive heating, unstable arcs, and turbulent gas coverage, all of which are detrimental to weld quality. By utilizing genuine Lincoln Electric parts, operators can ensure consistent current transfer and laminar gas flow, which are paramount for achieving X-ray quality welds in industries such as aerospace, petrochemical, and power generation.

This product is supplied as a package of two, providing professionals with necessary redundancy for critical projects. It is compatible with a wide range of torch configurations, including the air-cooled 17 and 26 series, as well as the water-cooled 18 series. This versatility makes it a staple inventory item for workshops handling heavy-plate welding where 5/32" tungsten is required. The robust construction withstands the thermal cycling inherent in high-amperage welding, resisting deformation and thread seizing better than generic alternatives. Whether you are welding aluminum with AC or steel with DC, the integrity of your torch consumables dictates the stability of your arc. Trust the Lincoln Electric KP4752-532 to deliver the reliability required for precision industrial applications.
