WARNING
Risk of injury from electric shock!
Contact with live parts, e.g. welding current sockets, is potentially fatal!
• Follow safety instructions on the opening pages of the operating instructions.
• Commissioning may only be carried out by persons who have the relevant expertise of
working with arc welding machines!
• Connection and welding leads (e.g. electrode holder, welding torch, workpiece lead,
interfaces) may only be connected when the machine is switched off!
Faulty assembly!
If system components are not carefully plugged in or not completely connected, they
may detach during moving and cause severe injury.
• Always completely plug in, connect or engage system components.
CAUTION
Risk of injury due to electrical current and compressed air!
Only carry out the following tasks once the power source is securely switched off and
there is no compressed air in the system!
• Switch off the welding machine!
• Cut off the compressed air supply at the source!
• Disconnect all mains plugs!
