Care, maintenance and disposal
General Under normal operating conditions, the welding system requires only a minimum of care
and maintenance. However, it is vital to observe some important points to ensure the weld-
ing system remains in a usable condition for many years.
Safety
At every start-up - Ensure that the mains plug and mains cable as well as the welding torch / electrode
holder are undamaged. Replace any damaged components
- Ensure that a proper ground earth connection has been established to the workpiece
- Check that there is an all-round clearance of 0.5 m (1 ft. 8 in.) around the device to
ensure that cooling air can flow in and out freely
WARNING! Work that is carried out incorrectly can cause serious injury and 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.
WARNING! An inadequate ground conductor connection can cause serious inju-
ry or damage. The housing screws provide a suitable ground conductor connec-
tion for grounding the housing and must NOT be replaced by any other screws
that do not provide a reliable ground conductor connection.
NOTE! Air inlets and outlets must never be covered, not even partially.
