Oxy-hydrogen generator is also called brown gas generator, Acrylic Polishing Machine, Water Welding Machine, or HHO gas generator, which is able to separate clean soft water (H2O) into hydrogen and oxygen gases, using a small amount of electric power through water electrolysis. These gases are then mixed and delivered for wide use, such as welding, flame polishing, heating etc to replace use of LPG or other gas for fuel.
For welding, it featured low cost, welding fact, safety and low energy consumption.
