Review on 🔥 MT70 Arc Welding Black by Christopher Bates

These replacement OEM tips for the Weller SP-12 soldering iron are hard to find. There are two tips in a sealed plastic package. You need to carefully remove the old tip with pliers and insert the new tip with a friction fit. Some people recommend heating the iron to make the tip easier to remove (thermal expansion). I was able to take mine off while the iron was cold.
