A blow lamp
is a portable heating device that uses a fuel source and compressed air to create a powerful flame. It’s commonly used for various tasks, including soldering, brazing, heating, and glassworking.
Types
- Propane : Use propane gas as the fuel source and are widely available.
- Butane : Use butane gas and are often smaller and more portable.
- Gasoline blow lamps: Use gasoline as fuel and offer a higher heat output.
Components of a Blow Lamp
- Fuel tank: Holds the fuel source.
- Pump: Pressurizes the fuel.
- Torch head: Mixes the fuel and air to create the flame.
- Ignition mechanism: Ignites the flame.
Applications of Blow Lamps
- Soldering: Heating metal joints to melt solder.
- Brazing: Joining metals using a filler metal that melts at a lower temperature than the base metals.
- Heating: Warming up metal objects for bending or shaping.
- Glassworking: Heating glass for shaping, annealing, or fusing.
- Outdoor cooking: Used for cooking food or boiling water.
Safety Precautions
- Fuel handling: Handle fuel with care and avoid spills.
- Flame control: Use the flame control valve to adjust the flame size.
- Ventilation: Ensure proper ventilation to avoid inhaling harmful fumes.
- Fire safety: Keep the blow lamp away from flammable materials.
- Personal protective equipment: Wear gloves, goggles, and a heat-resistant apron.
