Review on 🔥 Weller WES51 Compatible Heat-Set Insert Installation Guide for M2, M2.5, M3, M4, and M5 Inserts for Effective Assembly of 3D Printed Components by Tony Wilson

They fit and work with my Weller WE1010NA digital soldering station. I bought these to replace another set of heating inserts that only came in 2 sizes so I'm glad they cover more inserts. I like the fact that these tips fit better on the earbuds I use. This way, with a heated iron, I can lift the inserts and insert them into the hole in one motion. But they aren't so tight that they interfere with pulling the iron out when the insert is in place. This makes installation much faster and easier! I use these insert tips for 3D printed parts, mostly PETG. I run the iron at 500°F and it works great.
