What is Oxyhydrogen Generator/ Carbon Steel Cutting Machine :

Oxyhydrogen Generator/ Carbon Steel Cutting Machine consumes water and electricity, electrolyze water into H2 and O2, we can use H2 and O2 as source of flame replacing acetylene or natural gas or other fuel. Oxyhydrogen Generator/Metal Cutting Machine is used for welding, cutting, polishing, brazing, glass processing and jewelry processing. Also can burst with other fuel together for heating.

Multi-functions application of Oxyhydrogen Generator/Carbon Steel Cutting Machine:

1.Carbon Steel Cutting of machine building industry,shipyard,steel structure processing plant. 

2.Continuous casting slab cutting of Steel Plant.


3.Cooperate with manual cutting torch, semi-automatic cutting machine, shape cutting machine, CNC cutting machine to instead of traditional fuel gas.

Features of Okay Energy Oxyhydrogen Flame Cutting compared with acetylene propane etc. gas fuel:

1. Oxyhydrogen gas flame is concentrated. Preheating time is short in the same energy condition.


2.The heat affected zone of oxy-hydrogen flame is small.

3.Oxyhydrogen Cutting is barely have hang slag, cutting section have a good vertical.

(The left is Oxy-hydrogen Cutting picture, right is acetylene cutting picture.)

4.Oxyhydrogen cutting has no pollution, no black gas, it is environment friendly and not harm for people's body.

Oxy-hydrogen Cutting:

2H2+O2à 2H2O

it just formed water vapor in the cutting process, no any carbon emissions.

Acetylene cutting:


there is carbon dioxide emissions.

Oxygen-propane cutting:

C3H8+5O2à 3CO2+4H2O,

there is carbon dioxide emissions.

                                                                                                                                                                                                                                  Furthermore, Hydrogen gas is avirulent insipidity, but acetylene, propane and other industrial gas include sulphide,lead compounds and etc. harmful substances, they will cause respiratory disease if workers inhaled.

5.Energy saving effect is prominent.

(1) Oxyhydrogen Generator/Metal Cutting Machine uses water and electricity, electrolyze water to H2 and O2, no need gas cylinder, this way saves the cost of gas cyliner's rent,handling,storage.

(2) Oxyhydrogen cutting produces some low pressure oxygen by itself, preheating oxygen can be saved, there just need some hyperbaric oxygen.


Oxy-hydrogen Cutting can save energy by 50% compared with Oxy-acetylene cutting and save energy by 30% compared with Oxy-propane cutting.

Why use Okay oxyhydrogen generator as Metal Cutting Machine:

1. Maximum Safety --Steady, reliable fuel delivery.Fuel is available immediately after machine is switched on.No gas cylinder which can rupture or explode.--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. Environmentally Friendly --The Oxyhydrogen Gas fuel generated by our Oxyhydrogen Generator burns completely without creating pollutants, toxic fumes, or public nuisance.--Does not generate hydrocarbons, carbon monoxide, or carbon dioxide.


3. High Mobility --Our Oxyhydrogen Generator come equipped with wheels to facilitate moving the generators to the job, not the other way around.--Our Oxyhydrogen Generator immediately generates fuel as needed, no need for dangerous gas cylinders.--Fuel can be used for long periods of time without overheating peripheral equipment.


4. High Temperature & high-energy

--Calorific value is 34000Kcal/kg.

--The Oxy-hydrogen flame temperature is over 2800c, it is straight, less heat loss and high-efficient.It could melt refractory metals and none-metals. 


5. Low Cost & Maximum Economy--Oxyhydrogen gas is generated only using electricity and pure water. The cost of electricity and water reduces more than 40% compared with LPG, Propane, and Acetylene fuel.

--Both economical and practical.Energy Saving more than 30% compared with traditional LPG, Propane, and Acetylene fuel.

6. Low Heat Loss --Use of oxyhydrogen fuel provide a more focused heat source with less heat loss, maintaining a more comfortable, safer, lower fatigue working environment.

7. Catalysis characteristic

Hydrogen is an active catalyst which can be mixed with air to feed in to catalyze and combust all solid, liquid, gas fuel.It also can speed up the reaction process, promote combustion to be completely.

8. Using by producing

Oxyhydrogen generator can supply gas as user demand by adopting the advanced automatically control technology, no gas storage. 

9. Wide application range

Oxyhydrogen Generator is suitable for all industries which needs fuel gas to do flame processing,especially flame cutting,flame welding, heating.  

Unique Patented 9 Systems Features of Okay Energy Oxyhydrogen Generatorcompared with other manufacturers':


Okay Energy Oxyhydrogen Generator

Others manufacturers'

1.Power Supply

IGBT frequency conversion technology, conversion efficiency is as high as above 90%, stable and reliableto exchange AC turn to DC.

Silicon controlled rectifier or MOS tube rectifier technology, low efficiency to AC to DC. Unstable Current causes the gas production is not stable.

2.Electrolysis cell

Integration formed electrolysis cell, no any gas and liquid leakage.

Adopts in Series, piece together way, there is one seal ring between each polar plate to prevent gas and liquid from leakage. Each electrolysis cell have dozens of sealing rings, the cell cannot work as long as there is one seal occur leakage.

3.Electrolytic process


Dynamic self-circulation electrolytic process, purifier is installed in electrolyte circulation pipeline, it can clean the electrolysis cell automatically.

Static electrolysis process, the cell is easy to be dirty, some of the manufacturers use dynamic electrolytic system, but there is no automatic cleaning filtering device.


4.Electrolysis polar plate


Special activity alloy material surface treatment, low overpotential and no leakage between the polar plates, the gas production efficiency is high.


Using the method of drilling in plate to realize the gas and liquid flow, these holes with gas and liquid flowing can cause leakage of currents, the gas production efficiency is low.


5.Moisture separation system

Centrifugal compulsive moisture separation device, can achieve Moisture separation 100%, and always keep blue flame.


Using gravity to do separation of moisture. It can’t do separation completely due to the hydrogen and oxygen gas flow fast. The cell temperature will rise after long time using, the moisture content will increase in oxy-hydrogen gas, then the flame will be red, flame temperature will be lower.


6.Pipeline system

seamless stainless steel tube, no any rubber hoses absolutely, no gas or liquid leakage, ensures the safety and reliability

Using PU hose more or less to connect gas path.It will appear gas or liquid leakage phenomenon after a period of time in using or after backfire.

7.Anti-backfire system

Adopt patented wet-type anti-backfire and dry-type flashback arrestor and automatic safety valve device, build in automatically decompression and recover device, prevent from backfire, no need reset by manual.

Adopt dry-type arrestor to prevent backfire, if backfire happens it needs to reset by manual. After several backfire, the rubber gasket in arrestor will damaged, flashback arrestor will lost effectiveness.

8.Gas pressure stabilizer

Build in pressure stabilizing device, have a smart sensor device to detect user's gas demand for realizing adjustment automatically of gas output and ensuring gas output is equal to the user's gas consumption, ensure the stability of the gas output pressure, maintain the stability of the fire. This feature is particularly important for automated assembly line operations.

When the user's gas consumption is less than the gas production, it will cause machine shut down automaticallythe internal over-voltage protection and When the internal pressure drops, it automatically turns on. During automatically shutting down and turning on, the pressure fluctuations will lead to flame instability which may cause the inconsistency of the product processing.

9.Heat dissipation system

Unique duct design and larger space for heat dissipation to meet the needs of the work for 24 hours under high temperature of 40 degrees in summer.

The internal device is installed close, less space for heat dissipation, bad cooling in summer. It will result in:(1) shut down automatically for thermal protection (2) moisture with gas to reduce the flame temperature, affect product quality.
