2.3.2. Block protections
This welding machine is equipped with various safety devi-
ces that stop the machine before it can suffer damage.
In the event of a malfunction, the letter E may appear on
the display Z, followed by a flashing number:
52 = Start button pressed during start-up.
53 = Start button pressed during thermostat reset.
In both cases, release the start button.
The machine stop is signalled by the flashing LED (J).
When this occurs, it signals:
1) During the start-up phase, the power status of the

2) After the start-up phase, incorrect supply voltage.
3) With the machine running, that the voltage has fallen
below 118V.
4) With the machine running, that the supply voltage is above
280V.
5) During welding, that the voltage exceeds 300V.
To restore operation, check the voltage. Then shut off the AC
switch, wait 5 seconds, and switch it on again. If the problem
has been corrected, the welding machine will begin opera-
ting again.
NOTE: If the supply voltage is below 170V at start-up, no
LED will light and the fan is powered.
