brown gas water welding machine OH400

What is oxygen hydrogen generator(water welding machine/browns gas generator):

Oxygen hydrogen generator consumes water and electricity, electrolyze water into hydrogen gas and oxygen gas, we can use H2 and O2 as source of flame replacing LPG, Propane, Acetylene fuel or natural gas or other fuel.
OH400 water welding machine which also called hydrogen oxygen generator or browns gas generator can be used for welding, heating and sealing etc.

  • Advantages 
    • Advantages of hydrogen oxygen generator,water welding machine,browns gas generator

      1. Maximum Safety 

      a. Steady, reliable fuel delivery. Fuel is available immediately after machine is switched on. No volatile fuel tanks which can rupture or explode.

      b. Multiple safety devices, including overheating and in-sufficient water cut-off switches, will automatically turn off power to ensure the safety of both equipment and user.

      2. Environmental Friendly 

      a. The Fuel generated by our machines burns completely without creating pollutants, toxic fumes, or public nuisance.

      b. Does not generate hydrocarbons, carbon monoxide, or carbon dioxide.

      3. High Mobility

      a. Our generators come equipped with wheels to facilitate moving the generators to the job, not the other way around.

      b. Our generator immediately generates fuel as needed, eliminating the need for dangerous awkward gas tanks.

      c. Fuel can be used for long periods of time without overheating peripheral equipment

      4. High Temperature & Calorific value

      a. Calorific value is 34000Kcal/kg

      b.The flame temperature is over 2800°,it can melt refractory metals and none-metals 

      5. Low Cost & Maximum Economy

      a. Fuel is generated using only electricity and clean soft water.

      b. Both economical and practical when compared to the currently used LPG, Propane, or acetylene.

      6. Low Heat Dispersal 

      Use of this fuel provide a more focused heat source with less heat loss, maintaining a more comfortable, safer, lower fatigue working environment.
