Keep these labels clean and legible at all times.
• The machine has been constructed to state-of-the-art standards in line with any applicable
regulations and industrial standards. Only trained personnel may operate, service and re-
pair the machine.
• Technical changes due to further development in machine technology may lead to a dif-
fering welding behaviour.
In the event of queries on installation, commissioning, operation or special conditions at the
installation site, or on usage, please contact your sales partner or our customer service
department on [phone].
