Function 2T / 4T :
The use of the torch trigger can managed in 2 ways: 2 times or 4 times.
2 times : when the trigger is pressed, the weld starts. When the trigger is released, the weld stops.
4 times: when the trigger is pressed for the first time, the weld starts When the trigger is released, the weld continues. When the trigger is pressed
for the second time, the weld stops. This will allow the operator to weld for an extended period of time without having to hold the trigger.
4 seconds after the weld has started, if no current is measured, the unit immediately interrupts the weld (only on Nomadfeed 425-4).
At the end of the weld, the unit automatically manages the fusion of the wire at the end of the torch and the gas protection.
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 (only on Nomadfeed 425-4) :
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.
