Operational
description
B
The device must stand upright. If the device lies down it can not function properly, as liquid
propane gas flows through the propane regulator to the burner nozzle, and that leads to
disturbances.
Connecting the torch:
Connect the torch to the cylinder regulators or with a central gas supply to the supply points
with the approved hose according to EN 559. Secure the connection with hose clamps. If leakage
is suspected, check using soapy water.
Lighting and regulating the torches:
(using the valves on the torch)
Note: The torch works on the needle injector principle and the following
method of lighting it should therefore be adopted.
In order to assure safety, appropriate flashback arrestors should be installed.
Welding, brazing, heating, etc.:
1.
Put an appropriate welding or heating attachment into the handle of the torch. Check that
the cone at the end of the attachment is intact.
2.
Close both valves (
D
and
E
) on the handle.
3.
If the regulator is fitted with a needle valve, this should be opened. Set the recommended
working pressure by using the regulator's pressure adjusting screw. The same applies to
supply points if a gas pipeline is used.
4.
Open the oxygen needle valve (
D
) on the handle and allow the gas to purge the hoses for a
short time. Long hoses and small welding nozzles require a longer purge time. Maintain a
small gas flow.
5.
Open the torch fuel gas valve (
E
) on the handle and allow the gas to flow for a short time.
Purge as above.
6.
Light the torch.
7.
Regulate the size and type of flame with the valves (
D
and
E
) on the handle. The torch is
now ready for use.
Extinguishing the flame:
Welding, brazing, heating, etc.
First close the fuel gas valve (
E
) on the handle and then the oxygen valve (
D
).
