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.

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.
