The WELLER NT4 is a conical replacement soldering tip designed for fine-detail soldering work in electronics assembly, repair, and rework applications. Part of the NT tip series, it features a 0.047-inch point diameter and an overall length of approximately 0.39 inches (25/64 inch), making it well-suited for precision work on small components, surface-mount pads, and tight lead spacing. This tip is installed and replaced by electronics technicians, HVAC controls technicians, and electrical trade professionals working with low-voltage circuit boards and control components. The conical geometry delivers a concentrated heat path for accurate placement of solder on small joints.
This tip is intended for controlled bench soldering environments where fine-point accuracy is required. It fits the WMP Micro Soldering Pencil and compatible Weller soldering stations in the NT series platform. Typical applications include PCB rework, wire tinning on small-gauge conductors, component replacement on control boards, and prototype assembly. The compact tip size is particularly useful when working in dense board layouts where adjacent components require clearance.
Compatible with the Weller WMP Micro Soldering Pencil and Weller soldering stations that accept NT series tips, as stated by the manufacturer.
Allow the soldering station to cool fully and power it down before removing or installing a tip. Use the appropriate tip-removal tool or heat-resistant grip to avoid burns and tip damage. Tin the new tip with fresh solder immediately after first heat-up to protect the plating and extend tip life. Follow the soldering station manufacturer's guidelines for tip insertion depth and seating.
