A pencil torch is a diminutive specialized tool that emits a flame to heat nonflammable items, such as for soldering or for warming pipes for bends, among other uses. The small size of a pencil torch makes exact positioning of the flame possible in areas with cramped working space. Larger torches emit larger flames and provide less control; they're not intended for use in confined spots. Pencil torches operate on butane fuel, producing a clean-burning flame.
Hold the pencil torch in one hand with the bottom pointing up.
Hold a can of butane in the other hand. Make sure the cigarette lighter filler tip is affixed to the spray nozzle on the can.
Press the butane tip into the pressure fitting on the torch and press it inward.
Remove the butane can when a slight amount of butane escapes from the torch. This indicates that the torch is full of fuel.
Put on safety glasses or goggles.
Turn the “On/Off” gas control dial counterclockwise to the “On” position while holding the torch in one hand. You should hear gas escaping.
Light a kitchen match with the other hand and hold the flame near the tip of the torch. The flame of the match will light the butane.
Turn the gas control dial clockwise to make the flame smaller or counterclockwise to increase the flame size.
Direct the flame of the pencil torch on metal items to heat pipes, solder or braze.
Turn the “On/Off” dial clockwise to the “Off” position to extinguish the flame after use.
Set the pencil torch on a nonflammable surface with the tip overhanging a surface so the hot tip does not burn objects or people.
