ABSTRACT:
A cable monitoring system, which monitors failure of a plurality of cables connecting a power supply and a welding gun, has voltage detection lines connected to arbitrary two points of each of the cables, an insulating transformer a primary side of which is connected to the voltage detection lines of each cable, and a failure detector connected to a secondary side of the insulating transformer and detecting failure of each cable based on voltage on the secondary side of the insulating transformer for each cable.
