A blowtorch is a tool that produces a flame by mixing fuel, usually propane or acetylene, with oxygen. This combination creates a high-temperature flame, which is used for various tasks such as soldering, welding, and brazing metals. Blowtorches are commonly used in construction, metalworking, and even culinary applications, like caramelizing sugar on desserts. Blowtorches come in different sizes and designs, ranging from handheld models to larger, industrial versions. Safety features, such as flame control and protective gear, are essential when using a blowtorch to prevent accidents and injuries. Proper training is recommended to ensure safe operation.
