- Instant wetting using less solder
- Non-corrosive, non-hygroscopic and non-conductive flux
Only an ultra thin wall of solder separates flux and work. Five core design eliminates flux voids found in single-cored solders and provides closer controlled ratios of flux to solder. Extra active, Ersin Rosin Flux is non-toxic in use and free of objectionable odors. Flux residue does not need to be removed after soldering. All alloys are of the highest purity and are carefully formulated and independently assayed. Alloys (Sn/Pb): 60/40.
