About oxy-hydrogen welding generator: Oxy-hydrogen jewelry welding generator can set fire to water by electrolyze water into hydrogen gas and oxygen gas. We can use H2 and O2 as the fuel of flame replacing LPG, propane, acetylene fuel, natural gas or others. The oxy-hydrogen flame is cleaner & more efficient than other traditional flame. What kind of technology can change water into fire? 1. The principle is based on the theory of electrolysis. 2. To electrolyze water into pure hydrogen and oxygen. 3. Oxy-hydrogen flame is a high temperature energy source which can be used for jewelry welding, acrylic polishing etc., which is economical, reliable, safe and environmental
