Start the generator first, then connect the welding unit. The idle voltage
should be set to approx. 240 volts, adjust the voltage if needed. When
turning the generator off, disconnect the welding unit first.

The working output power of the generator decreases by about 10% per
1,000 m of altitude.
During the welding process no further devices connected to the same
generator should be operated.

Service and Repair

As the machine is used in applications that are sensitive to safety con-
siderations, it may be serviced and repaired only on our premises or by
partners who were specifically trained and authorized by us. Thus, con-
stantly high standards of operation quality and safety are maintained.
IMPORTANT!
Non-compliance with this provision will dispense the manufacturer from
any warranty and liability claims for the machine and any consequential
damage.
When serviced, the welding unit is automatically upgraded to the technical
specifications with which the product is currently shipped, and we grant
a three-month functional warranty on the serviced unit.
We recommend having the unit serviced at least every twelve months.
In Germany, keep in mind the second check-up according to BGV A3!
