A gas torch or blow torch is a torch that uses a fuel to heat objects. Propane and Map Pro (a type of propane) are the most common fuel sources for gas torches. Gas torches are used for a variety of jobs, the most common being soldering copper pipes. Gas torches are also used to  loosen stuck and rusted bolts, remove air bubbles from epoxy finishes, strip non-leaded paint, activate shrink wrap and shrink tubing, weld certain materials, braze metal and even destroy weeds. Here are the basic parts: 

1. Fuel canister
