 HHO Oxyhydrogen technology uses water as medium to electrolyze water into H2 and O2, fire them to formed Oxyhydrogen Flame. The temperature of Oxyhydrogen flame is as high as 2800 degrees so that it can weld very fast. The quality and speed of Oxyhydrogen Flame welding method is higher than Liquid gas's.

Welding Industries

Oxyhydrogen flame ideal for:

1)OEM, transformers and power generators;

2)electric motor and power generator repair shop;

3)electric motor work shops;

4)large air conditioning supplies;

5)solar collectors;

6)manufacturing of large statues;

7)manufacturing of trophies, chandeliers, statues and other brass articles etc;

8)gold silver platium jewelry welding and repair;

9)musical instrument welding & repair;

10)others copper welding & soldering


Advantages and Features

1. Safety

Oxy-hydrogen just uses water and electricity, no gas bottle, no hydrogen gas storage, no leakage and explosive danger.

2. Convenience

it can work just with water and electricity, every litre water can be used 7~8 hours. But Liquid gas bottle need to be changed by manual moving, it is very inconvenient.

3. Cleanliness

Oxy-hydrogen combustion just produces little water vapour, there is no harm to the pharmaceuticals. But Liquid gas combustion produces carbon dioxide, carbon monoxide and nitrogen compounds which will impact on the quality of pharmaceuticals.

4. High Efficiency

The speed of Oxy-hydrogen Flame welding method is higher than Liquid gas's.



Unique hydrogen technology

1. The power supply:Inverter DC resonance power supply is made of imported IGBT power valve. The electrolysis is 30% higher efficiency and electrolysis current is stable and adjustable. It can long-term work 24-hours continuous.


2. Electrolysis Cell:It adopts large precise mould to integrated formed, prevent from explosion and leakage, work life is long. It is suitable for kinds of complicated working condition.


3. Heat dissipation system:Unique reasonable structured duct design radiation design and larger space of three-dimensional air flue for heat dissipation to ensures the radiation effect,meet the need of the work for 24 hours under high temperature of 40 degrees in summer.No need to cooling by water cycle.


4. Safe system:Safe system adopts multi-level swing type water seal design, detects and controls the safe water level automatically, perfect combination by multilevel wet-type flashback arrestor technology, automatic safety valve technology and dry-type fire resistance technologydry-type flashback arrestor, ensure 100% prevent from backfire.


5. Control system:Control water level and pressure automatically, exception catch setting, stabilize the pressure device.


6. Water and gas separation system:Gravity swing water and gas separation system, water vapor collection and backflow design, ensure that there is no mositure in the gas output pipe.

1.Can the oxyhydrogen machine be used in boiler renovation?

 Of course,it has become a hot spot in our industry research for energy saving and low carbon emissons.


2. Does the Oxyhydrogen water welding machine make big noises?How about the decibels?

 Not really , only the fan sound.


3. How about the security of the oxyhydrogen machine ?which aspect should pay attention to ?

 There are multiple tempering inside to protect the machine from back-fire. Besides,There is back-fire function between the flame arrestor and the nozzle. 

Notice: Be quick when you turn off the heat and replace the wearing parts (nozzle) half a year, so as to avoid back-fire .


4. Is the temperature same among the different machine models?

 Yeah,the temperature is same but the gas output are different.


5.Is there any influences using different machine models?

 You’d better to communicate with our professionals to choose the right machine models.The gas 

output has a direct influence on the use effect.
