What are the differences between a butane torch and a propane torch?

The main differences between a butane torch and a propane torch are the fuel they use and the temperature they can reach. Butane torches use butane gas, which burns at a lower temperature than propane. Propane torches use propane gas, which burns at a higher temperature. This means that propane torches are generally hotter and more suitable for tasks that require higher heat levels, such as metalworking or Plumbing. Butane torches are often more portable and easier to use for smaller tasks like cooking or crafting.
