Weller T0050104799 Soldering Iron Knife Tip 1 in

Product Description

The WELLER T0050104799 is a knife-style replacement soldering iron tip designed for precision soldering work. The knife tip geometry allows technicians to access tight spaces, cut solder bridges, and drag-solder component leads in a single controlled stroke. This tip measures 1 inch in diameter and fits the WELLER T0052922699 soldering iron handle. It is installed and used by electronics technicians, HVAC controls specialists, and electricians performing board-level repairs on control boards, relays, and terminal connections.

This knife tip is suited for fine soldering applications where a standard chisel or conical tip would be too blunt or too narrow for the task. Typical use cases include reworking surface-mount and through-hole components, trimming solder on wire terminations, and servicing PCB assemblies found in residential and light commercial HVAC controls, electrical panels, and industrial equipment. The tip is sold individually and is intended as a direct replacement when the existing tip shows signs of oxidation, pitting, or poor heat transfer.

Installation Notes

Tip replacement should be performed by a qualified electronics technician or trained tradesperson. Allow the soldering iron to cool completely before removing or installing a tip to prevent burns and avoid damaging the heating element or tip retaining mechanism. Use the appropriate tip-removal tool or wrench as specified by the iron handle manufacturer — do not use pliers on the tip body. Tin the new tip immediately after first heat-up to protect the contact surface and extend service life.
