Laser gas supply from cylinders
•
The safest, easiest, and most economical way of supplying
laser gas is to use individual cylinders.
•
The gas flow is interrupted when changing cylinders or
bundles.
•
Only use clean conduits for the connecting lines (oil-free,
grease-free, and dust-free on both the inside and outside).
•
Do not clean the hoses with solvent.
•
Do not use lubrication when fitting the hoses.
•
Take care that all maintenance work is carried out with the
utmost cleanliness.
Central laser gas supply (fixed piping)
Multiple gas cylinder systems are recommended for wall mounting
and for uninterrupted operation. The switch-over is carried out
manually or automatically.
The following demands are made on fixed piping:
•
Copper or stainless steel pipes (refrigerator quality) must be
used for the fixed piping.
•
Have the piping done by qualified professionals.
•
To avoid contamination during transport and storage, the ends
of the pipes must be securely sealed.
•
Necessary connection points must be made with forming gas.
When braze welding or orbital welding stainless steel pipes, no
residue may remain in the pipe interior (e.g. flux from braze
welding).
•
Alternatively, clamping ring screws made of the same material
can be used.
•
The assembled tubing must be tested for leaks before being
put into operation.
•
The pipes must be subsequently purged with inert gas and
laser gas (final cleaning with nitrogen) in order to flush
moisture and residual gas from the lines.
•
The gas supplier must be consulted in all cases.
Note
A central nitrogen supply gas tank is not recommended.
