Care, maintenance and disposal
General Under normal operating conditions, the device requires only a minimum of care and main-
tenance. However, it is vital to observe some important points to ensure the welding sys-
tem remains in a usable condition for many years.
Safety
Every start-up - Check all hosepacks and the ground earth connection for damage. Replace any dam-
aged components.
- Check feed rollers and inner liners for signs of damage. Replace any damaged com-
ponents.
- Check the wirefeeding hoses for damage. Replace any damaged components.
- Check contact pressure of feed rollers and adjust if necessary.
- Check that all screw connections between the robot, wirefeeder holder and wire-feed
unit are secure.
Whenever the
welding torch or
torch hosepack is
changed
Whenever the welding torch or torch hosepack is changed, ensure that the coupling point
is clean and dry. Remove any coolant that has escaped from the coupling point.
WARNING! Work that is carried out incorrectly can cause serious injury or dam-
age. All the work described below must only be carried out by trained and quali-
fied personnel. Do not carry out any of the work described below until you have
fully read and understood the following documents:
- this document
- all the operating instructions for the system components, especially the safe-
ty rules
WARNING! An electric shock can be fatal. Before starting the work described be-
low:
- turn the power source mains switch to the "O" position
- disconnect the power source from the mains
- ensure that the power source remains disconnected from the mains until all
work has been completed
After opening the device, use a suitable measuring instrument to check that elec-
trically charged components (e.g. capacitors) have been discharged.
CAUTION! Risk of scalding by hot system components. Before starting work, al-
low all hot system components to cool down to room temperature (+25 °C, +77
°F). For example:
- coolant
- water-cooled system components
- wire-feed unit drive motor
