• Production Working Principle
Multi-function oxy-hydrogen welding machine takes water as main consumable material. Water mixed with potassium hydroxide (KOH) is electrolytic to generate the mixed Hydrogen and Oxygen gas.
Hydrogen as fuel, oxygen as combustion-supporting.
Flame temperature is up to 2800℃。The product after gas combustion is water vapor, non-toxic and does not pollute the environment.
● Main Application
It can be used in welding metal or alloy; soldering denture or maintaining dental equipment; soldering metal wires, especially enamelled wires in motors; mending and soldering eye-glasses frame; fusing LED wafers; making and mending gold jewelry, platinum jewelry and other jewelry; processing quartz glass; sealing small quartz glass bottles; processing accessories and decorations; polishing acrylic or organic glass sheet, letters and so on.
Since it powerful gas output, it is also used for carbon cleaning for cars.

• FAQ (Frequently Asked Questions)
Q. What should we prepare for the machine?
A: 1) Power supply. Single phase AC220V +/- 10% or AC110V+/-10%, or DC12V / 24V.
2) Water. Distilled water, or pure water, or tap water.
3) KOH (potassium hydroxide) chemical powder. If the machine is shipped to you by sea, KOH chemical powder will be enclosed in the package.
4) Alcohol. You can use laboratory alcohol, industrial alcohol, drinking alcohol, medical alcohol but alcohol concentration should be more than 75%.
Except the above items, other are all enclosed in the machine package.
We have demo video to teach you how to use the machine.
Q. How to make electrolytic solution?
A: Mix 750g potassium hydroxide in 5L water. Stir them until it is dissolved completely.
We have demo video to teach you how to make solution.
Q. What is the normal AMP value?
A: When the machine works, the normal AMP value is approximately 10A.
If you find the value is lower than 10A, please check if the solution strength is enough according to 750g KOH : 5000ml water.
If solution strength is enough, please empty solution tank and wash it by clean water completely. Then fill new solution in it.
Q. Besides KOH (potassium hydroxide), may I use other chemical powder or salt?
A: Absolutely NO!!! Just KOH (potassium hydroxide) is allowed for the machine. Any other chemical powder or salt will destroy the machine.
Q. When I receive the machine, I find it does not work, what’s wrong with it?
A: 1) Please check if you have added chemical powder as required.
2) What kind of chemical powder are you using? Is it KOH (potassium hydroxide)?
3) Please check if electrolytic solution strength is enough as per 750g KOH : 5L water.
Q. When liquid level declines, should I make new solution to replenish in the machine?
A: No need. When liquid level declines, you just need to replenish water in machine until level up to Normal Water Line. No need to add chemical powder.
Only for the 1st time to use the machine, or change new electrolytic solution, potassium hydroxide must be added.
Q. What cause red or yellow flame color? And how to solve this problem?
A:
Reason 1: Exceeded electrolytic solution is filled in.
Solution: You just need to pour extra electrolytic solution and make it in the range of normal water line, the problem will be solved.
Reason 2: Water vapor gas hose.
Solution: Remove water vapor from gas hose, or change a new gas hose.
Reason 3: Dirty nozzle.
Solution: Stab the hole of nozzle with needle and clean out dirty things.
Reason 4: Dirty electrolytic cells.
Solution: Empty the cells completely, then clean the cells with clean water for several times until it is clean. Then make new electrolytic solution with 750g KOH and 5000ml water and fill in machine cells.
Q: What cause little gas output? And how to solve this problem?
A:
Reason 1: Low ampere value.
Solution: Make new electrolytic solution with correct proportion of 750g KOH to 5000ml water. Then confirm every cell’s ampere value is normal 12A.
Reason 2: Gas Leakage.
Solution: Turn off flame torch and power on machine, then smear soap liquid on every connection parts to find out leakage point, then maintain it.
Reason 3: Jammed gas flow
Solution: Loosen the small pipe inside the filter cup. Maintain the flashback arrestor or flame torch.
Q: What cause flashback? And how to solve this problem?
Reason 1: Gas leakage.
Solution: Turn off flame torch, power on the machine, smear soap liquid on every connecting joints of the machine to find leakage point and maintain it.
Reason 2: Flashback arrestor is broken down.
Solution: Maintain flashback arrestor or change a new one.
Q. What material is the electrolysis chamber made of?
A: It is made of 316# stainless steel.
Q. May I purchase it through Aliexpress?
A: Sure. Link to our Aliexpress tore as below:
