The WELLER WLTS4IR30 is a screwdriver-style replacement soldering tip designed for use with compatible Weller soldering irons. The tip measures 0.16 inches (4.00 mm) in diameter and is sold in a pack of three, making it a practical choice for technicians who work through tips regularly. Screwdriver tips are well suited for drag soldering, pad tinning, and desoldering tasks where a flat, broad contact surface improves heat transfer. This tip type is a standard consumable in electrical, electronics, and light assembly work where reliable thermal contact and repeatable results matter.
This tip is intended for use in bench-level soldering and rework applications across electronics, electrical panel work, and light fabrication. The screwdriver geometry suits tasks such as component lead soldering, wire termination, and flux-assisted drag soldering on PCB assemblies. Packaged in a quantity of three, it is well suited for shops or field technicians who want spares on hand. Weller specifies compatibility with a defined set of iron handles and kit configurations, listed below.
Compatible with the following Weller iron handles and kits: WLIR3012A, WLIR3023C, WLIR3023G, WLIR3023I, WLIR3023M, WLIRK3012A, WLIRK3023C, WLIRK3023G, WLIRK3023I, WLIRK3023M, WLSK3012A, WLSK3023C, WLSK3023G, and WLSK3023I.
Soldering tip replacement is performed by electricians, electronics technicians, and assembly workers maintaining soldering irons during normal service. Always allow the iron to cool fully and disconnect it from power before removing or installing a tip to avoid burns and equipment damage. Tip installation typically requires no tools beyond hand pressure; consult the iron handle documentation for the correct seating and locking procedure. Do not force a tip that does not seat correctly, as improper fit can reduce heat transfer and damage the heating element.
