Review on Optimized Search: Bernzomatic PC3 Copper Phosphorus Brazing Welding Solution by John Jones

These are good soldering irons, but they are very small in diameter (little common material) and don't perform as well as Stay-Silv soldering irons (or many other manufacturers' soldering irons). FYI, if you are a DIY enthusiast trying to solder with a MAPP gas torch, do not buy the smaller Bernz-O-Matic MAPP gas torch, buy the largest one. Small doesn't generate enough heat for most projects (only for fairly small solder joints with low heat dissipation).
