Safety information for universal feeder UVR-300 / UVR-400
In addition to the general safety information in these instructions, the following safety
information applies to handling the devices:
Risk due to accelerated welding studs
The welding studs are transported using compressed air and are therefore greatly
accelerated.
Always ensure that the stud feed hose is intact.
Before each system start, check that the stud feed hose is correctly inserted
on both sides, into the feeding unit (feeder) and the gun or welding head.
Only use stud feed hoses from Soyer GmbH.
Never bridge the safety pressure switch at the cover hood (do not trigger the
switch if the protective hood has been removed).
Do not carry out a functional check when the cover hood is opened and the
compressed air is connected.
Regularly check that the safety interlock at the stud feed hose connection
piece moves smoothly (connecting piece M3 - M8).
Only ever use system parts which are matched to the stud diameter to be
transported
(see chapter “7 Converting the universal feeder” on page 34).
Stud feed malfunctions due to misalignment
In the feeder, a few screws are marked red (see the
example on the right). If these screws become loose,
the feeder must be readjusted at the factory.
Do not loosen these screws.
Notes regarding compressed air
Only use dry and cleaned compressed air as energy source.
