KP4752-332 - Lincoln Electric Caliber TIG Collet Body, 3/32 in (2.4 mm), 10N32 Style, 2-Pack

Technical Overview of the Lincoln Electric KP4752-332

The Lincoln Electric KP4752-332 is a premium collet body from the manufacturer's Caliber™ TIG consumable line, engineered to meet the rigorous demands of industrial welding environments. This specific component is designed to accommodate 3/32-inch (2.4 mm) tungsten electrodes, serving as the critical interface between the collet and the torch head. It is manufactured to precise tolerances to ensure concentricity and optimal electrical contact, which are vital for maintaining a stable arc and prolonging the life of the tungsten electrode.

Compatibility is a key feature of the KP4752-332. It is universally designed to fit industry-standard 17, 18, and 26 series TIG torches. This includes air-cooled models (17 and 26 series) and water-cooled models (18 series), making it a versatile stock item for fabrication shops utilizing mixed equipment. This part serves as a direct replacement for the legacy Lincoln Electric part number KP2032-4B1, offering an updated manufacturing standard while retaining full backward compatibility. Furthermore, it corresponds to the industry-standard cross-reference number 10N32, allowing for easy identification and integration into existing inventory systems that utilize the 10N numbering scheme.

Constructed from high-grade copper alloy, the KP4752-332 collet body excels in thermal management and electrical conductivity. Efficient heat dissipation is essential in TIG welding to prevent the overheating of the collet and the torch head, particularly during high-amperage applications. By maintaining a cooler operating temperature, this collet body helps prevent the deformation of the collet itself, ensuring that the tungsten remains securely gripped throughout the welding operation. This product is supplied in a package of two, providing welders with a necessary backup to minimize downtime during consumable changeovers.

For procurement and maintenance teams, standardizing on the Lincoln Caliber series ensures consistency across welding stations. The KP4752-332 integrates seamlessly with other Caliber consumables, including collets, gas lenses, and alumina nozzles, to form a cohesive gas delivery system. Proper assembly of these components is critical for shielding gas coverage; the precision threading and machining of this collet body ensure a gas-tight seal against the torch body and the ceramic cup, reducing the risk of atmospheric contamination in the weld pool.
