Weller WLTK4IR30 Soldering Iron Knife Tip 3-pack

Product Description

The WELLER WLTK4IR30 is a knife-style replacement soldering tip designed for use with Weller cordless and corded soldering irons. The knife tip profile allows technicians to cut, slice, and shape solder, heat-shrink tubing, and thermoplastic materials with precision. The tip measures 0.16 inches (4.00 mm) in diameter and is sold as a pack of three, making it practical for bench shops and field service kits. Licensed electricians, electronics technicians, and HVAC controls installers rely on knife tips when working in tight wire-routing areas or when trimming insulation materials during low-voltage control wiring.

This tip is suited for light electrical work, electronic component rework, and low-voltage control panel wiring in both residential and commercial applications. The knife geometry is especially useful when desoldering or soldering flat connector tabs and when cutting heat-shrink in confined spaces. Packaged in a quantity of three, the WLTK4IR30 is a practical stocking item for service vehicles and shop benches where tip wear is frequent.

Installation Notes

Tip replacement should be performed by a qualified electrician or electronics technician with the soldering iron fully powered down and cooled before handling. Allow the iron to reach a safe handling temperature before removing or installing a tip to avoid burns. Follow the iron manufacturer's tip-seating instructions to ensure proper thermal contact and avoid damage to the heating element. Refer to applicable NEC guidelines when using soldering equipment in electrical panel or low-voltage control wiring environments.
