Weller T0050102899 Soldering Iron Knife Tip

Product Description

The WELLER T0050102899 is a knife-style replacement soldering tip designed for precision soldering work. The knife tip profile allows the technician to make angled contact with solder joints, making it well suited for drag soldering, cutting through flux residue, and working in tight component areas. At 0.10 mm tip diameter, this is a fine-work tip intended for detailed electronic assembly, rework, and repair tasks. It is installed and serviced by electronics technicians, field service engineers, and trade professionals who maintain or repair circuit boards and wiring harnesses in HVAC controls, electrical panels, and industrial equipment.

This knife tip is suited for bench-level rework and field repair applications where a fine, angled contact point improves access and control. Common use cases include soldering surface-mount components, repairing damaged PCB traces, and performing wire-to-board connections in residential and light commercial control assemblies. It ships individually and is intended as a direct replacement consumable for compatible Weller soldering irons.

Compatibility

Designed for use with Weller soldering iron model T0052922899. Confirm iron model compatibility before ordering, as soldering tips are not universally interchangeable across Weller product lines.

Installation Notes

Soldering tip replacement should be performed by a qualified technician familiar with the soldering iron in use. Allow the iron to cool fully before removing or installing a tip to prevent burns and avoid damaging the tip seat. Use the manufacturer-recommended tip removal tool or follow the iron's service guide to avoid overtightening. Follow applicable workplace safety practices when working with soldering equipment near energized assemblies.
