Clean energy with excellent economy, precision, and safety using water as fuel.
The Sunwelder is a device that generates "hydrogen and oxygen gas" through the electrolysis of water in its generator tank. The hydrogen-oxygen mixed gas generation device "Sunwelder SW-123" is a self-gas generating type that does not require any gas from high-pressure cylinders. Additionally, the gas produced in the generator tank is used as a torch flame at the generated low pressure, making it exempt from high-pressure gas safety regulations. It is a safe device that can be easily handled and used by anyone. The mixed gas produced from water and electricity maintains a stable component ratio, providing a clean flame with no soot and excellent straightness. It is environmentally friendly, has a long lifespan, and offers low running costs, making it an economically advantageous generation device. 【Features】 ○ Portable gas generation device ○ Continuous operation without interruption through automatic water supply ○ Exempt from high-pressure gas safety regulations ○ Provides a clean flame with no soot and excellent straightness For more details, please contact us or download the catalog.

Company information
Sanwell Corporation, as a manufacturer of hydrogen-oxygen gas generation devices, has achieved a cumulative total of over 3,800 units since its establishment in 1983, receiving high praise from numerous users, including manufacturing sites and research institutions. Our flagship product, the "Sanwelder," is an advanced hydrogen-oxygen gas welding machine that stably generates hydrogen-oxygen gas using water and electricity, creating a tiny flame with a high-temperature combustion flame. The Sanwelder leverages its high-precision combustion flame to accommodate precision processing of various materials, including metals, resins, glass, and precious metals. In particular, in metal welding, it prevents oxidation and achieves precise bonding. In the manufacturing sites of semiconductors and electronic devices, it is utilized for fine local heating and frame processing. Additionally, stable operations can be conducted even in clean room environments, boasting high reliability in the production of medical devices and high-precision products. Furthermore, by utilizing the characteristics of hydrogen-oxygen gas, which burns with a tiny flame at a maximum temperature of about 2800°C, it demonstrates exceptional performance in welding and heat treatment of glass, resins, and precious metals. Moreover, the highly reducing hydrogen-oxygen gas leads to a higher quality finish in the precision processing of precious metals and glass.
