•Fuel Type: It typically operates using kerosene or paraffin. Unlike modern gas torches, it requires preheating with a small amount of methylated spirits to vaporize the fuel before ignition.
•Operation: The black plunger on the left is a pump mechanism used to build air pressure inside the fuel tank. This pressure forces the liquid fuel up a tube to the burner head, where it is heated and expelled as a high-pressure, blue flame.
•Applications: These blow lamps are versatile tools used for general heating, soldering metal pipes, paint stripping, pre-heating large metal castings before welding, and even some cooking applications.
•Design: The device has a sturdy, traditional design, often made from metal with a handle integrated into the tank.
