Weller T0050102799 Soldering Iron Knife Tip

Product Description

The WELLER T0050102799 is a knife-style replacement soldering tip designed for precision soldering work. The knife tip profile allows technicians to access tight joints, cut through flux residue, and make controlled contact with small surface-mount pads or wire terminations. Measuring approximately 4.5 inches in length and 0.7 inches in width, this tip mounts to compatible Weller soldering irons and provides a fine working edge suited to detailed electrical assembly and repair tasks. Licensed electricians, electronics technicians, and field service pros working on control boards, low-voltage wiring, or component-level repairs will find this tip appropriate for close-tolerance applications.

This knife tip is intended for bench or field soldering applications where a standard chisel or conical tip does not provide adequate control. Typical use cases include reworking PCB solder joints, soldering fine-gauge wire connections on HVAC control boards, and general electronics repair in commercial or residential service environments. The compact tip geometry makes it well-suited to confined spaces on populated circuit boards.

Installation Notes

Tip replacement should be performed by a qualified technician with the soldering iron powered off and fully cooled. Allow adequate cool-down time before handling the tip to avoid burns. Use the appropriate tip removal tool or wrench specified for the iron model to avoid damaging the heating element or tip seat. Do not force or overtighten the tip during installation.
