Advantages

Multi-Functional Precision Machine for Diverse Applications: This model is an all-in-one solution, expertly combining the functions of a gold welding machine, an acrylic edge polisher, and a versatile HHO torch. It is specifically designed for a wide range of tasks including repairing jewelry, melting metals like gold and silver, flame polishing acrylic edges for a crystal-clear finish, and even delicate electronics welding.
Precision Welding: 3000°C Concentrated flame achieves precise welding. Our flame focuses down to a fine point, heating only the joint. Ideal for precious metals like jewelry to prevent metal loss.
Jewelry Welding Without the Discoloration: Oxygen-acetylene torches leave oxidation on gold, silver, and platinum. Our hho flame burns clean. Only water vapor touches the metal. The weld area stays bright. No pickling. No polishing to remove fire scale. Delicate chains, jump rings, and prongs come out of the weld with their original finish intact.
From Frosted Edge to Glass Finish in Seconds: A saw-cut acrylic edge looks white and rough. Sanding makes it clearer but takes minutes and leaves scratches. Our hho flame does it in seconds. One pass melts the surface. Surface tension does the smoothing. The edge becomes transparent, glossy, and scratch-free. No sandpaper.
Safe & Convenient: Oxyhydrogen generator can produce gas automatically without gas cylinder. Just need pure water & electricity as fuel. No worry for cylinder explodes.The machine will turn on or off automatically by detecting the gas pressure.The gas output volume is adjustable. Easy to operate.
Globally Recognized Certifications and Patented Technology: Our hydrogen welding machines are proudly certified with prestigious international accreditations including CE, FCC, and ISO, confirming compliance with rigorous global standards for safety, electromagnetic compatibility, and quality management systems. OEM and ODM options are available for custom branding.
