&
D
UTY CYCLE
•
Thermal protection : thermal protection indicator turns on and the cooling time is about 2 to 5 min
according to external temperature.
•
Leave the machine connected to the supply after welding in order to let it cool down
•
The welding unit describes an output characteristic of "constant current" type. The duty cycles following
the norm EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table here below :

MAINTENANCE
•
Refer all servicing to qualified personnel.
•
Disconnect the generator and wait until the ventilator stopped before working on the unit. Inside the
device, voltages and current are dangerous.
•
2 or 3 times a year, remove the steel cover and blow off the dust with compressed air. Let check the
electrical connections (with an insulated tool) and the insulations by qualified personnel.
•
Regularly control the state of the cord. If this supply cable is damaged, it must be replaced by the
manufacturer, its after sales service or a similarly qualified technician to avoid any danger.
ADVICES
•
Respect welding polarities and currents indicated on the electrode packaging
•
Remove the electrode from the electrode holder when you do not use it.
•
Leave the inlets free to allow in/out air circulation.
