Review on 🔥 Superior Quality Weller ST7 ST3 Soldering Conical for Reliable Results by Badpuppy Warton

2-18-13. I bought a Weller 35 soldering iron to replace my 50 year old Weller block (which still works great) that I can no longer get nozzles for. These tips are ideal for small and very small soldering jobs. They're official Weller products and are perfect for turning 35. Cheaper tips aren't worth the frustration and wasted time.
