PLUMBING TOOLS Blow torches are used to heat metal during soldering. Gas can be supplied via a portable, reusable gas bottle.
PLUMBING TOOLS Above: portable blow torch with disposable gas cylinder.
PLUMBING TOOLS Flux is applied to prevent oxidisation of the surfaces of connectors.
PLUMBING TOOLS Pipe work is heated using a blow lamp. Solder is melted to a liquid with the blow lamp, and is used to weld connectors and pipes together. Once cooled, the solder returns to a solid, forming a watertight seal.
PLUMBING TOOLS Left: oxy-acetylene bottles. One bottle contains oxygen, the other contains acetylene, which is a fuel source. The gasses inside the cylinders are compressed and are in liquid form: once the gasses leave the cylinder, they become gas and are mixed to form a flammable mixture.
PLUMBING TOOLS THE FIRE TRIANGLE HEAT FUEL OXYGEN In order for anything to burn, 3 elements, as above, need to be in place. Oxy-acetylene welding & burning provides these elements.
