Soldering with the power generated by this hydrogen torch system is a terrific alternative to using pressurized fuel and oxygen tanks in your shop! This system is extremely safe, easy to use, easy to light with a push-pull shut off mechanism. Visual controls keep you aware of the solution levels and power levels and allow you to set the power you need for any given soldering task. The system produces energy by using electricity and by utilizing hydrogen and oxygen atoms from an electrolyte solution (required for operation), creating a safer, cleaner and more economical hydrogen/oxygen fuel. (Consequently, with the added benefit, of a Clean Brazing Surface, No CO2 emissions, No Oxidation, a Precise Micro Flame, and a Long-Life lasting FLUX).
