Weller 1237S Soldering Tip

The Weller 1237S is a 1/4" thread-on soldering tip designed for use with Weller 7400, 7500, 7760 and 7770 soldering irons. It suits technicians and hobbyists who need a direct replacement tip for those specific stations. It is not for users of other iron models or thread sizes.

Capacity and Headroom

The tip operates at 120 V and draws 33 W, reaching a maximum temperature of 800 °F. This provides sufficient heat for general electronics and wiring tasks on compatible stations. It will not fit irons outside the listed model numbers or deliver higher temperatures than specified.

Questions about this item

Will the 1237S tip thread onto the Weller 7400 iron I already own?

Yes, the 1/4" thread fits the 7400, 7500, 7760 and 7770 models listed by the manufacturer.

How can I confirm the 1237S tip is heating properly after fitting it?

The tip should reach the rated maximum of 800 °F when powered from a 120 V supply drawing 33 W.

Does the 1237S package include a soldering iron or just the tip?

Only the 1/4" thread-on tip is supplied; a compatible Weller iron such as the 7400, 7500, 7760 or 7770 must be purchased separately.
