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 due to incorrect connection!
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
accessory components.
• Accessory components are detected automatically after the power source is switched on.
