CAUTION
Damage due to the use of non-genuine parts!
The manufacturer's warranty becomes void if non-genuine parts are used!
• Only use system components and options (power sources, welding torches, electrode
holders, remote controls, spare parts and replacement parts, etc.) from our range of
products!
• Only insert and lock accessory components into the relevant connection socket when the
machine is switched off.
Damage to the machine due to stray welding currents!
Stray welding currents can destroy protective earth conductors, damage equipment and
electronic devices and cause overheating of components leading to fire.
• Make sure all welding leads are securely connected and check regularly.
• Always ensure a proper and secure electrical connection to the workpiece!
• Set up, attach or suspend all conductive power source components like casing, transport
vehicle and crane frames so they are insulated!
• Do not place any other electronic devices such as drillers or angle grinders, etc., on the
power source, transport vehicle or crane frames unless they are insulated!
• Always put welding torches and electrode holders on an insulated surface when they are
not in use!
Mains connection
Requirements for connection to the public mains network
High-performance machines can influence the mains quality by taking current from the mains
network. For some types of machines, connection restrictions or requirements relating to the
maximum possible line impedance or the necessary minimum supply capacity at the interface
with the public network (Point of Common Coupling, PCC) can therefore apply. In this respect,
attention is also drawn to the machines' technical data. In this case, it is the responsibility of
the operator, where necessary in consultation with the mains network operator, to ensure that
the machine can be connected.
