50 W Weller Solder Element

This 50 W heating element fits Weller soldering irons that use a 1/4 inch thread-on connection. It operates at 120 V and reaches a maximum temperature of 1,000 degrees Fahrenheit. The part is UL Listed for safety compliance. It serves as a direct replacement for worn or damaged original elements.

Replaces Elements In 7400 7500 7760 7770 Models

This element restores function to compatible Weller irons when the original heater fails or no longer reaches temperature. The upgrade is worth it when tip life drops or heat recovery slows during prolonged joints. It returns the iron to its factory 50 W rating without modification. Buyers needing higher wattage or a different thread pattern cannot use this part.

Thread-On Installation Requires Cool Iron

Installation is a simple thread-on procedure once the iron is completely cool and unplugged. Cross-threading the 1/4 inch connection is the most common error and can damage the iron housing. Overtightening may strip the soft threads or crack the ceramic core. Always verify the model number matches 7400, 7500, 7760 or 7770 before fitting.

Questions about this item

Will the 1/4" thread fit my Weller 7400 soldering iron?

Yes, the element threads directly into Weller models 7400, 7500, 7760 and 7770.

How do I install the element without damaging the threads?

Screw the element in by hand until it seats firmly, then tighten gently with a wrench; over-torquing strips the 1/4" threads.

How often will I need to replace this 50 W heating element?

Replace the element when it no longer reaches the 1,000 °F maximum temperature or shows visible pitting on the tip.
