The pointing out of any difficulties
and their elimination
The supply line is attributed with the cause of the most com-
mon difficulties. In the case of breakdown, proceed as follows:
1) Check the value of the supply voltage.
2) Check that the power cable is perfectly connected to the
plug and the supply switch.
3) Check that the power fuses are not burned out or loose.
4) Check whether the following are defective:
•
The switch that supplies the welding power source
•
The plug socket in the wall
•
The mains switch
NOTE:
Given the required technical skills necessary for the
repair of the welding power source, in case of breakdown we
advise you to contact skilled personnel or our technical ser-
vice department.
