A blowtorch, or blowlamp, is a fuel-burning tool for applying flame and heat for 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, and is still used in the UK. Liquid-fuelled torches are pressurised by a piston hand pump, gas torches are self pressurised by the fuel's evaporation.
