Replacement soldering iron assembly for 21-10115 and 21-10120 Tenma soldering stations.
This is a nice iron. But if you change tips, you will see that the heating element is fully exposed when you remove the existing tip. The fact that there is no protective metal cover over the element is very good for maximum heat transfer between the element and the tip (no additional layer of metal to slow things down), but it also means the element is fully exposed and subject to damage. I have two of the #21-10115 solder stations, and I am about to order my third replacement soldering iron because of damage to the heating element. Some of the ceramic coating just fell off of one of the heating elements as I was changing tips, so it is time for another replacement iron.
Also note that there are irons available on Ebay that look identical to the one that is used in this soldering station, but they are NOT compatible with this soldering station. The Ebay irons usually have a thermistor built into the heating element to sense temperature. This requires a 5-wire connection. The MCM irons do not use a thermistor, apparently sensing the element resistance as it heats up (just guessing here). Therefore, the wiring of the connector is different and not compatible. So, be gentle, and consider a spare iron.
I really like the 60 watt digital soldering station that uses these, however this part is the weak link of the system. While these heat up very, very quickly and have very long lasting tips - the real issue is that the construction is weak... they loosen, crack and eventually break in the handle area. I also had one where the temperature sensor failed almost immediately, and these were on back-order for the warranty replacement. Frustrating!

I have been dealing with MCM for over 30 years now. If I didn't like the service I'd would have found a different supplier 30 years ago. For most of my needs they are the 1st stop on my shopping list.
