A propane torch is a handheld tool that uses propane gas as fuel to produce a high-temperature flame. It is commonly used for tasks such as soldering, brazing, and heating materials. The torch typically consists of a fuel tank, a nozzle, and an adjustable flame control. These torches are popular in various industries, including plumbing, metalworking, and culinary arts. They can also be used for outdoor activities like camping and welding. Safety precautions are essential when using a propane torch, as the flame can reach very high temperatures and pose fire hazards.
