What is "safeflame"

SafeFlame is a welding technology that combusts hydrogen and oxygen to create a flame. The gases are obtained by electrolyzing water, and then mixed and ignited as they exit the torch nozzle. The technology is inherently safer than conventional acetylene- and propane-based welders, because those fuels are held in pressurized tanks that can explode if mishandled.

By fine-tuning the proportions of the two gases, different types of flames can be produced for different applications. The flame can be stoichiometric, oxidising or reducing.
