Questions about this item

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

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?
