Butane torches come in handy for a variety of tasks around the house, but when the fuel runs out, it's time to get to work ...

If you have never filled a butane torch lighter before, the process can be a little intimidating. Don't worry, SlashGear will walk you through how to do it.

How can I tell if my butane torch is running low during use? When a butane torch is low on fuel, the flame may start to sputter, shrink, or fail to maintain its usual heat and intensity.

Attempting to use propane in a butane model could damage the torch head or even cause an explosion. Conversely, you shouldn't put butane fluid in a propane tank either.
