Weller T0050101299 Soldering Iron Knife Tip 2.5in

Product Description

The WELLER T0050101299 is a knife-style replacement soldering tip designed for precision soldering work. The knife profile allows technicians to cut, scrape, and bridge solder joints in applications where a standard conical or chisel tip would be impractical. At 2.5 inches in diameter, this tip fits the corresponding Weller soldering iron handle and delivers focused heat transfer at the cutting edge. It is used by electricians, electronics technicians, HVAC controls specialists, and bench repair professionals who need tight control over solder flow and joint access.

This knife tip is suited for light electrical assembly, component rework, wire tacking, and fine lead soldering on circuit boards or terminal strips. The knife geometry is particularly useful when working in confined spaces or when separating solder bridges between closely spaced pads. Trades servicing control boards, low-voltage wiring harnesses, or electronic HVAC components will find this tip well matched to detail work at the bench or in the field.

Key Features

• Knife-style tip profile for cutting, bridging, and scraping solder joints
• 2.5-inch tip diameter sized for compatible Weller iron handles
• Replacement tip — direct swap with no modification required

Compatibility

Designed for use with Weller soldering iron model T0052921399N. Verify handle compatibility before ordering, as Weller tip series are not universally interchangeable across iron families.

Installation Notes

Tip replacement should be performed by a qualified technician with the iron powered off and fully cooled. Allow the iron to reach operating temperature before attempting to tin or use the new tip. Follow the iron manufacturer's tip installation guidance to avoid damaging the heating element or tip retention mechanism. Always tin a new tip immediately after first heat-up to extend service life and maintain thermal transfer.
