Blow torch

A blowtorch (USA usage), or blowlamp (British usage, or rare or archaic), is a fuel-burning tool used for applying flame and heat to various applications, usually metalworking.

Early blowlamps used liquid fuel, carried in a refillable reservoir attached to the lamp. Modern blowtorches are mostly gas-fuelled. Their fuel reservoir is disposable or refillable by exchange. The term "blowlamp" usually refers to liquid-fuelled torches still used in the UK. Liquid-fuelled torches are pressurized by a piston hand pump, while gas torches are self-pressurized by the fuel evaporation.
