Heating / Soldering
According to the application and the heat required, either a combination of a fuel gas (propane, acetylene, hydrogen, methane etc.) and oxygen is used for heating works or a fuelgas (s.propane equipment) only. By soldering works an alloy is heated up to the melting point. This is done by hard soldering also with a fuel gas / oxygen flame and by soft soldering with a fuelgas flame with surrounding air (s.propane equipment).
