(blast lamp, blow lamp), a heating unit in which heat is generated by a flame fueled by a liquid combustible, such as alcohol, kerosine, or gasoline; the combustion products in the blowtorch create an extended flare. Blowtorches are used to heat parts and melt solder when soldering at temperatures to 1100°C. They are also used to heat soldering irons and other tools. The atomizer type of blowtorch is the most common. Gasoline blowtorches generate the most heat and are the most convenient to use. Tank capacity varies from 0.1 to 2 liters.


A small, portable blast burner which operates either by having air or oxygen and gaseous fuel delivered through tubes or by having a fuel tank which is pressured by a hand pump. Also known as blast lamp; blowpipe.
