so if I use a solid core solder and some flux, it would last longer than useing rosen core solder?
Us RMA core solder and RMA or solid solder and RMA, either way. Use a new tip, keep it clean, and don't over heat the tip. Like I said, once the tip starts to pit, its a lost battle.
Solder selection matters to, lead free solder can eat at a tip made for lead solder faster. That is why they sell lead free tips.
