The product is suitable for flame polishing of acrylic crafts and organic glass, and can also be used for experimental teaching of water electrolysis to produce hydrogen and oxygen in schools. Key Features ◼Long Service Life: Built up of iron and brass with baking paint and spraying paint processes, the product has high hardness, long service life, and good resistance to corrosion, rust, impact, and deformation. ◼Excellent Performance: With 200W power, the product can quickly electrolyze pure water to produce hydrogen and oxygen (17.17-19.81Gal/h) to generate a clean and intense high-temperature flame (3632-5432℉), ensuring thorough and uniform polishing results. In addition, the flame can be adjusted for your convenience. ◼User-friendly Design: High-definition and accurate ammeter, pressure meter, and water volume viewing window can display the status of each index of the machine, which is convenient for your operation. ◼Thoughtful Design: The large capacity water tank (0.26Gal) ensures that it can work for a long time after being filled with water, without refilling frequently. The water inlet is at the top of the polisher, making it very easy to fill.

Please make sure the tank is filled with clean water and all the connectors are fixed firmly. 2.It is recommended to use industrial alcohol to filter the produced gas, if not, you can also use clean water instead. 3.Please note that any accumulation of water in the hose will cause the flame to turn yellow, and should be discharged promptly. Please take care to check the hose connections for air leaks. 4.Please note that the electrolyte is alkaline, if accidentally contaminated, please rinse it with water in time. 5.If the phenomenon of tempering and implosion occurs, do not panic and worry, it is due to improper operation, air leakage, or gun malfunction, please check the pipeline or replace the gun. 6.Beware of electrical safety hazards. When using such tools, please take necessary personal protective measures and keep the product out of reach of children. 7.Please note that the product requires the addition of electrolytes (not included) for the first time, after which it can be added directly to purified water. Please unscrew the nozzle knob to remove the residual gas after you turn off the machine.
