Blow torches come in many variations. One of the most common types is a simple hand-held propane torch. A host of professionals use blow torches for a wide range of purposes. Some blow torches have integrated lighting systems, but the simple ones require manual ignition.
Step 1
Stand the torch upright in a clear area, devoid of combustible materials.

Step 2
Hold the lighter or sparker in front of the torch's nozzle and activate it. The sparker activates when you squeeze the handle, which rubs flint against a striker, thereby creating a spark. Repetitively squeeze the handle until the torch lights. You can simply ignite the lighter with the flame in front of the nozzle.
Step 3
Turn the dial on the torch slowly until the propane ignites with the flame or sparker. Remove the lighter or sparker and place it away from the work area.
Step 4
Adjust the flame by turning the dial until you have the size of flame you want.
Warning
Always keep combustible materials away from your torch to avoid accidentally igniting them.
