the front panel indicates a fault which prevents the equipment
from functioning.
The yellow LED indicates two fault types:
1. overheating caused by an excessively intense duty cycle. In
this case, stop welding and leave the power source switched

In this case, wait till the LED switches off, indicating normali-
sation of the supply voltage and then resume welding.
