Butane torches can be used in many different ways and for many purposes, but by far the most common of these is for soldering in jewelry making. These small torches can attain temperatures high enough to melt silver solder, as well as other solders. Butane is inexpensive and easy to find for refilling the torch. The small size of these torches makes them easy to handle. Another way they can be used is for soldering electronic components and for quickly and efficiently heat-shrinking tubing in electrical installations.
Verify that your torch has been filled with butane. Some torches use replacement butane cells and others use fuel from lighters or even disposable lighters themselves as the fuel cell.
Make sure your work area is clean and heat resistant. If you are working around wires or other items that could be affected by the heat, use a sheet of thin metal or other non-flammable material to shield the heat from those items.
Hold the torch in your preferred hand. Pull the trigger or push the ignition button, depending on your torch model, and light the torch.
Working carefully and slowly; heat the desired item to the required temperature with the torch. If you are working with solder, be mindful of splattering solder, as hot solder can cause severe burns.
Release the trigger or ignition button when you are done, and set the torch in a safe place to cool. The tip of the torch may be very hot, so do not rest it against anything flammable.
Butane torches can reach temperatures well into the 2,500 degree Fahrenheit range and should not be used carelessly, as fires and burns could be likely if case of incorrect use.
