Thermal protection:
The thermal protection of the unit will kick in if the temperature of the conductors is excessive. In that case, the L05 LED activates and it is not possible
to weld while the temperature remains too high. If the thermal protection kicks in, leave the unit to cool down for 15 minutes.
Unit controls panel :
The settings of the unit can be changed using an SW 8 switch box on the electronic converter. To access the box, it is required to place the metal
case where the 4 buttons and the fuse holder are. This operation must be carried out by a qualified technician and when the unit is disconnected
from the power source.

Precisions regarding function SW4 :
This function gives access to totalisators of events that happened when the unit was used and shown as functions Fc1 to Fc6, displayed on the top
screen. Change the function by using buttons 10 and 11.
