By making hydrogen and oxygen via electrolysis of distilled water, Aquaflame 800 produces controllable and efficient heat source. Sole byproduct is water, and unit works without gas cylinder storage. Addition of deionized water, potassium hydroxide crystals, and MEK is occasionally required, and optional battery-operated torch lighter is available. Uses include acrylic flame polishing, micro-precision welding, soldering circuit boards, medical instruments, and dental/optical repair.
