5.1 General
WARNING
Risk of injury from electrical voltage!
Contact with live parts, e.g. power connections, can be fatal!
• Observe the safety information on the first pages of the operating instructions!
• Commissioning must be carried out by persons who are specifically trained in handling
power sources!
• Connect connection or power cables while the machine is switched off!
CAUTION
Risk of burning due to incorrect welding current connection!
If the welding current plugs (machine connections) are not locked or if the workpiece
connection is contaminated (paint, corrosion), these connections and leads can heat up
and cause burns when touched!
• Check welding current connections on a daily basis and lock by turning to the right when
necessary.
• Clean workpiece connection thoroughly and secure properly. Do not use structural parts of
the workpiece as welding current return lead!
Risk from electrical current!
If welding is carried out alternately using different methods and if a welding torch and
an electrode holder remain connected to the machine, the open-circuit/welding voltage
is applied simultaneously on all cables.
• The torch and the electrode holder should therefore always be placed on an insulated sur-
face before starting work and during breaks.
Accessory components and the power source itself can be damaged by incorrect connection!
• Only insert and lock accessory components into the relevant connection socket when the
machine is switched off.
• Comprehensive descriptions can be found in the operating instructions for the relevant ac-
cessory components.
• Accessory components are detected automatically after the power source is switched on.
Protective dust caps protect the connection sockets and therefore the machine against dirt and
damage.
• The protective dust cap must be fitted if there is no accessory component being operated on
that connection.
• The cap must be replaced if faulty or if lost!
Read and observe the documentation to all system and accessory components!
5.2 Scope of delivery
The delivery is checked and packaged carefully before dispatch, however it is not possible to exclude the
possibility of damage during transit.
Receiving inspection
• Check that the delivery is complete using the delivery note!
In the event of damage to the packaging
• Check the delivery for damage (visual inspection)!
In the event of complaints
If the delivery has been damaged during transport:
• Please contact the last haulier immediately!
• Keep the packaging (for possible checking by the haulier or for the return shipment).
Packaging for returns
If possible, please use the original packaging and the original packaging material. If you have any queries
on packaging and protection during transport, please contact your supplier.
