@Mark: I use the EndoPro270 at the highest setting (270degrees). The goal is to use one 2-3sec long burst of heat after you place the tip at the orifice of the canal or 1mm above it and activate while pushing laterally (not apically) and melt and shear off the GP handle. The assistant can grab the handle while you do this and you can say “Pull” when it’s cut through and that removes the handle. You then use a cool size 10 plugger to spread the molten segment of the GP at the orifice and spread it so it completely seals and covers the orifice, preferably not showing unset sealer seams (the latter helps you use an ultrasonic afterwards with water to quickly clean the chamber without the risk of removing sealer from inside the canal.) Good luck! 🙂
