KP2108-1B1 - Lincoln Electric KP2108-1B1 Contact Tip, 3/32 in, 3/8-16 Thread (10-Pack)

Precision Contact Tips for Heavy-Duty Welding

The Lincoln Electric KP2108-1B1 Contact Tip is a critical consumable component designed for industrial welding operations utilizing large diameter wires. Engineered to accommodate 3/32-inch (approximately 2.4 mm) welding wire, this contact tip is essential for applications requiring high deposition rates, such as heavy structural fabrication, submerged arc welding (SAW), or heavy flux-cored arc welding (FCAW). The tip is manufactured from a premium copper alloy, selected for its superior thermal and electrical conductivity, which helps minimize heat buildup and ensures efficient current transfer to the welding wire.

Mechanical precision is a hallmark of Lincoln Electric consumables. The KP2108-1B1 features a robust 3/8-16 mounting thread, providing a secure and vibration-resistant connection to the diffuser or torch body. This coarse thread design is durable and resists cross-threading during replacement, a common issue in harsh industrial environments. The internal bore is machined to tight tolerances to provide optimal electrical contact with the wire while preventing binding or erratic feeding, which can lead to arc instability and defects in the weld deposit.

Supplied in a convenient pack of 10, these contact tips allow facilities to maintain adequate stock levels for continuous production. Regular replacement of contact tips is vital for maintaining weld quality, as the bore wears over time due to the friction of the moving wire and electrical erosion. By using genuine Lincoln Electric parts, operators ensure compatibility with their existing equipment and maintain the performance standards expected from their welding systems.
