Why Choose Oxy-Hydrogen Generators?
1) Maximum Safety – No gas cylinders, no risk of leaks or explosions.
2) Environmentally Friendly – Produces only water vapor, no pollution.
3) Cost-Effective – Reduces electricity and water costs by over 40% compared to acetylene.
4) Low Heat Dispersal – Keeps the surrounding area cooler during use.
5) Excellent Quality – Provides clean and precise welding and cutting results.
6) Portable and Easy to Use – Ideal for on-site applications.


Applications in the Welding Industry
Oxy-hydrogen flames are ideal for:
1) OEM manufacturing and power generators
2) Electric motor and generator repair shops
3) Industrial workshops
4) Large air conditioning systems
5) Solar collectors
6) Manufacturing of large statues and sculptures
7) Production of trophies, chandeliers, and brass items
8) Jewelry and precious metal welding and repair
9) Musical instrument repairs
10) Copper and other metal welding and soldering

Other Applications:
1) Welding: Copper, gold, silver, iron, tin
2) Heating: Glass and various metals
3) Flame Polishing: Acrylic, Plexiglass



Advantages and Features
1. **Safety** – Uses only water and electricity; no gas bottles or storage needed, eliminating explosion risks.
2. **Convenience** – Operates with just water and electricity. One liter of water can last up to 7–8 hours. Unlike liquid gas, there’s no need to replace heavy bottles manually.
3. **Cleanliness** – Combustion produces only water vapor, making it safe for sensitive environments like pharmaceuticals. Liquid gas produces CO₂, CO, and nitrogen compounds that can affect product quality.
4. **Efficiency** – The oxy-hydrogen flame provides faster and more precise welding than traditional methods.

**Free Accessories Included:**
Torch and nozzle: 1 set
Soft pipe: 2m
Flame arrester: 1 unit
