What is the purpose of the barrel in a torch?

• A. To house the flame
• B. To mix the gases
• C. To connect to hoses
• D. To protect the user

Answer: (B)

The barrel of a torch plays a crucial role in the mixing of gases, which is essential for proper combustion. In a typical torch setup, fuel gas (such as acetylene) and oxygen are supplied through separate hoses. The barrel functions as the area where these two gases come together in the correct proportions before being ignited at the tip of the torch. An efficient mixing process ensures a stable and controllable flame, which is critical for various applications in pipe fitting and welding. A poor mixture could lead to an unstable flame or incomplete combustion, affecting the quality of work. While the other options provide elements that might be associated with torch design or safety features, they do not encapsulate the main function of the barrel itself. The design does not house the flame; it is not primarily intended to connect hoses—while it may serve this purpose indirectly—and while user protection is certainly a priority in torch design, it is not the primary function of the barrel. Thus, mixing the gases stands out as the central purpose of the barrel in a torch.
