General
6.1
Risk of injury due to electrical voltage after switching off!
Working on an open machine can lead to fatal injuries!
Capacitors are loaded with electrical voltage during operation. Voltage remains present for up to
four minutes after the mains plug is removed.
1. Switch off machine.
2. Remove the mains plug.
3. Wait for at last 4 minutes until the capacitors have discharged!
Incorrect maintenance, testing and repair!
Maintenance, testing and repair of the machine may only be carried out by skilled and qualified
personnel. A qualified person is one who, because of his or her training, knowledge and experience,
is able to recognise the dangers that can occur while testing welding power sources as well as
possible subsequent damage, and who is able to implement the required safety procedures.
Observe the maintenance instructions
• In the event that the provisions of one of the below-stated tests are not met, the machine must
not be operated again until it has been repaired and a new test has been carried out!
Repair and maintenance work may only be performed by qualified authorised personnel; otherwise the right
to claim under warranty is void. In all service matters, always consult the dealer who supplied the machine.
Return deliveries of defective equipment subject to warranty may only be made through your dealer. When
replacing parts, use only original spare parts. When ordering spare parts, please quote the machine type,
serial number and item number of the machine, as well as the type designation and item number of the
spare part.
Under the specified ambient conditions and normal working conditions this machine is essentially
maintenance-free and requires just a minimum of care.
Contamination of the machine may impair service life and duty cycle. The cleaning intervals depend on the
ambient conditions and the resulting contamination of the machine. The minimum interval is every six
months.
Cleaning
6.2
• Clean the outer surfaces with a moist cloth (no aggressive cleaning agents).
• Purge the machine venting channel and cooling fins (if present) with oil- and water-free compressed air.
Compressed air may overspeed and destroy the machine fans. Never direct the compressed air directly at
the machine fans. Mechanically block the fans, if required.
• Check the coolant for contaminants and replace, if necessary.
Dirt filter
6.2.1
The duty cycle of the welding machine decreases as an effect of the reduced cooling air volume. Depending
on the amount of dirt building up (at least every two months), the dirt filter has to be uninstalled and
cleaned regularly (e.g. by purging with compressed air).
