Weller T0050102999 Soldering Iron Knife Tip 2.5in

Product Description

The WELLER T0050102999 is a knife-style replacement soldering tip designed for use with compatible Weller soldering irons. The knife tip profile makes it well suited for cutting, scraping, and sealing thermoplastic materials, as well as drag-soldering and surface-mount work where a broad, angled contact edge is needed. The tip measures 2.5 inches in diameter and is a direct OEM-style replacement that maintains consistent heat transfer for reliable joint quality. Electricians, electronics technicians, and HVAC service techs who work with low-voltage wiring harnesses or control board repairs will find this tip a practical addition to their kit.

This tip is intended for bench-top and field soldering applications where a knife edge geometry improves access and control. It is specified for use with the Weller soldering iron handle T0052922899. Typical use cases include wire termination work, PCB rework, heat-shrink application, and thermoplastic cutting tasks encountered in trade service environments.

Installation Notes

Soldering tip replacement is typically performed by electronics technicians or licensed electricians. Allow the iron to cool completely before removing or installing a tip to avoid burns and thread damage. Use the appropriate tip removal tool or wrench if required by the handle design — do not force the tip by hand when hot. Follow the iron manufacturer's instructions for tip seating and initial tinning to maximize tip life.
