Weller W101 (100W) Spare Tip Nut
Weller W101 Spare Tip Nut, for use with the Weller 100W Soldering Iron. This is the retaining nut that holds the Weller Stained Glass Soldering Iron tip in place.
Do not over tighten your tip nut, as if too tight it will prevent the electromagnet from releasing to control the temperature. Nip up until finger tight then release it a quarter turn.
