Abstract
The present invention comprises: a spool (); a clamper (); a torch electrode (); a high-voltage power source circuit (); a non-bonding detection circuit (); a first changeover switch () switching a connection between the spool () and the high-voltage power source circuit () or the non-bonding detection circuit (); and a relay () turning on/off a connection between the clamper () and a spool side of the first changeover switch (), and comprises a control part () that sets the first changeover switch () to the high-voltage power source circuit side and turns off the relay () to generate electric discharge, and that sets the first changeover switch () to the non-bonding detection circuit side and turns on the relay () to perform non-bonding detection. Due to this configuration, electric corrosion of a wire clamper can be suppressed and non-bonding detection can be carried out with a simple configuration.
