Why use an Oxy-Hydrogen Generator?
1) Maximum safety – no gas cylinders or stored hydrogen, eliminating risk of leaks and explosions.
2) Environmentally friendly – produces only water vapor, making it pollution-free.
3) Cost-effective – reduces electricity and water costs by over 40% compared to acetylene.
4) Low heat dispersal – ideal for precise and controlled applications.
5) High-quality results – delivers superior welding and cutting performance.
6) Portable and flexible – easy to move and use in various settings.
Applications in the Welding Industry
Oxy-hydrogen flame is ideal for:
1) OEM, transformers, and power generators;
2) Electric motor and power generator repair shops;
3) Electric motor workshops;
4) Large air conditioning supplies;
5) Solar collectors;
6) Manufacturing of large statues;
7) Production of trophies, chandeliers, statues, and brass items;
8) Jewelry welding and repair (gold, silver, platinum);
9) Musical instrument welding and repair;
10) Other copper welding and soldering applications.
Other uses include:
1) Welding: Copper, gold, silver, iron, tin.
2) Heating: Glass and any metal.
3) Flame polishing: Acrylic, plexiglass.
Advantages and Features
1. Safety – uses only water and electricity, no gas bottles or storage, ensuring no leakage or explosion risks.
2. Convenience – operates with just water and electricity, where one liter of water can last up to 7–8 hours. Unlike liquid gas, which requires manual handling and frequent refills, this system is far more efficient.
3. Cleanliness – combustion produces only water vapor, making it safe for pharmaceuticals and sensitive environments. Liquid gas, on the other hand, emits CO₂, CO, and nitrogen compounds that can affect product quality.
4. Efficiency – offers faster welding speeds than traditional gas methods.
Free accessories included:
