Care, maintenance and disposal
General Under normal operating conditions, the power source requires only a minimum of care
and maintenance. However, it is vital to observe some important points to ensure it
remains in a usable condition for many years.
Safety
WARNING!
Work that is carried out incorrectly may result in serious injury or damage to prop-
erty.

WARNING!
An electric shock can be fatal.
Before starting the work described below:
▶
Turn the power source mains switch to the "O" position
▶
Disconnect the power source from the grid
▶
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 electric-
ally charged components (e.g. capacitors) have been discharged.
WARNING!
An inadequate ground conductor connection can cause serious injury or damage.
The housing screws provide a suitable ground conductor connection for earthing the
housing.
▶
The housing screws must never be replaced with different screws unless a reliable
ground conductor connection is established.
At every start-up - Check mains plug, mains cable, welding torch, interconnecting hosepack and
ground earth connection for damage
- Check that the device has an all-round clearance of 0.5 m (1 ft. 8 in.) to ensure that
cooling air can flow in and out freely
NOTE!
The air inlets and outlets must never be covered, not even partially.
Every 2 months - If present: clean air filter
