5. Illumination of the yellow LED (Ref. 3 - Picture 1 Page 4.) on
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
on until the LED switches off.
2. power supply too high/too low.
In this case, wait till the LED switches off, indicating normali-
sation of the supply voltage and then resume welding.
