Weller T0050100899 Soldering Iron Chisel Tip

Product Description

The WELLER T0050100899 is a chisel-style replacement soldering tip designed for use with compatible Weller soldering irons. The tip measures 1.80mm in diameter, making it well suited for through-hole component work, wire tinning, and general-purpose soldering tasks where a broad, flat contact surface improves heat transfer to the joint. This tip is a direct drop-in replacement for worn or oxidized tips and is the type of consumable that electronics technicians, HVAC controls techs, and electricians keep on hand for ongoing service work.

The T0050100899 chisel tip is intended for bench and field soldering applications across residential and light commercial service environments. It is compatible with the Weller iron model T0052921399N as specified by the manufacturer. Typical use cases include control board repair, low-voltage wiring connections, terminal block work, and sensor lead soldering on HVAC, electrical, and instrumentation equipment.

Installation Notes

Allow the soldering iron to cool fully before removing or installing a tip to avoid burns and prevent tip seizure on the heating element. Use the iron manufacturer-recommended tip removal tool or wrench where applicable — do not force a tip off with pliers, as this can damage the heating element sleeve. Tin the new tip immediately after first heat-up to protect the plated surface and extend service life. Dispose of worn tips in accordance with local regulations for metal waste.
