5. NGfL CYMRU GCaD www.ngfl-cymru.org.uk 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

6. NGfL CYMRU GCaD www.ngfl-cymru.org.uk 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

7. NGfL CYMRU GCaD www.ngfl-cymru.org.uk THE FIRE TRIANGLE HEAT OXYGEN FUEL In order for anything to burn, 3 elements, as above, need to be in place. Oxy-acetylene welding & burning provides these elements. PLUMBING TOOLS
