POWER SOURCE PROTECTIONS

11�1 Thermal protection
If the maximum permissible temperature for correct operation of the inverter is exceeded, the current output to the
welding machine is interrupted. In this condition, Err. 74 appears on the display.
The fan remains on to cool the inverter. When the correct temperature is reached, the error disappears and the
welding machine is ready to operate.
11�2 Lock protection
When the welding machine is switched on, a number of checks are performed on the power supply network to disable
welding machine operation in the event of a mains fault.
The anomalies checked are as follows; the presence of these anomalies is indicated on the display by Err. 76.
three-phase welding machines:
− the neutral conductor is connected instead of a phase conductor.
− no phase conductor is connected.
− -the supply voltage value is outside the permitted range.
single-phase welders:
− -the supply voltage value is outside the permitted range.
