The burner is the area of the blow lamp which determines the size and temperature of the flame. It can come in various shapes and sizes. For more information see What are the different types of blow lamp burner?
Piezo ignition
A piezo ignition enables the blow lamp to be lit without the use of an external flame.
The handle is used to control the direction and position of the flame by allowing the user to manipulate the blow lamp.
Flame control
The flame control allows the user to control the size of the flame from pin point, which is a hot blue flame, to a soft yellow flame. To create a hot flame, turn the flame control nozzle anti-clockwise, and to adjust to a cooler flame or turn off, turn it clockwise.
Coupling
The coupling on the blow lamp allows it to attach to a gas cannister. The gardening blow lamp can either have an EN417 (7/16″) coupling or a CGA 600 (1″ threaded) coupling.
