Weller WLTCH4LBA12 Soldering Iron Chisel Tip 3-pack

Product Description

The WELLER WLTCH4LBA12 is a chisel-style soldering iron replacement tip designed for use with compatible Weller soldering irons in the WLIR, WLIRK, and WLSK series. The tip measures 0.16 inches (4.00 mm) in diameter and ships in a pack of three, making it practical to keep spares on hand for continuous work. Chisel tips are the preferred shape for drag soldering, sweating connectors, and general-purpose through-hole and surface-mount work. Electricians, HVAC technicians, and electronics technicians reach for this tip profile when soldering heavier joints or working with wider pads that require broader heat transfer than a conical tip provides.

This tip is suited for light commercial and residential electrical work, control board rework, wiring harness assembly, and general bench soldering. The chisel profile transfers heat efficiently to flat and angled joint surfaces. The three-unit pack supports shop environments where multiple technicians share equipment or where tip rotation during extended soldering sessions is standard practice. Installation is straightforward on any compatible Weller iron in the supported series.

Installation Notes

Tip replacement should always be performed with the soldering iron powered off and fully cooled. Electricians and electronics technicians installing or swapping tips should avoid overtightening the tip collar to prevent damage to the heating element or tip seating surface. Follow the iron manufacturer instructions for tip insertion depth and retention. Work on energized circuits is not recommended during tip service.
