Care, maintenance and disposal
General Under normal operating conditions the spot welding gun 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.
In terms of maintenance intervals, always select the earlier time.
WARNING!
Machines that start up automatically can cause serious injury and damage.
In addition to these operating instructions, the safety rules issued by the manufacturer of
the robot and welding systems must also be observed. For your personal safety, ensure
that all protective measures have been taken and will remain in place for the duration of
your stay within the working area of the robot.
