    • Production Working Principle

    The machine takes water as main consumable material. Water is electrolyzed to generate Hydrogen and Oxygen. 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

    1) It is especially suitable for quickly polishing the side edges, concave surfaces, inner holes and curved edges of plexi-glass (acrylic) advertising crystal characters or craft carving products, which solves the problem that the ordinary polishing wheels cannot.

    2) It is especially suitable for the rapid transparent polishing of fine burrs of plexi-glass products. Suitable for all kinds of material thickness Acrylic rough side fast flame polishing, efficient and simple. Also suitable for carrying the machine to the field environment.

    3) Suitable for precision crafts such as open flame welding, small casting, small part quenching annealing, various wire welding, high temperature material testing, etc. in jewelry factory, gold shop, dental department, glass and other industries.

    • 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) NaOH (sodium hydroxide) or KOH (potassium hydroxide) chemical powder. If the machine is shipped to you by sea, NaOH 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 solution?

    A: Mix 250g chemical powder in 700ml 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 250g NaOH : 700ml 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 NaOH (sodium hydroxide) or KOH (potassium hydroxide), may I use other chemical powder or salt? 

    A: Absolutely NO!!! NaOH (sodium hydroxide) or KOH (potassium hydroxide) are workable 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 NaOH (sodium hydroxide) or KOH (potassium hydroxide)?

    3) Please check if solution strength is enough as per 250g : 700ml.

    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.

    Q: What material is the electrolysis chamber made of?

    A: It is made of 304# stainless steel.

    Q. How should I purchase the machine?

    A: Welcome to purchase from our Aliexpress store:
