Same here, I'll have to give that a try.I've thought about welding legs but haven't got there yet. When I build a new coil I pulse it on the lowest setting just enough until it stops smoking and that has helped to keep from burning the insulators but once in a while I'll scorch one.
With 50 packs of NR-R-NR coils for $2, is it worth welding up the wires?
Lightning Vapes sells Silicone insulators for Kanger coils, they must be more resilient than the rubber ones.
