Abstract
Methods and apparatus for identifying the occurrence of fusing electrical attachment during fusing operations are provided. After a conventional fusing operation is complete, an electrical signal is applied to the fusing electrode while the fusing electrode is returned to its home position. The electrical signal is monitored to determine whether a circuit path exists from the fusing electrode through the fused conductors to the ground electrode. The presence of a path would indicate that the fusing electrode has become attached to the fused conductors. An alternate embodiment is also described in which the force required to withdraw the fusing electrode is monitored while the electrode is returned to its home position. If the measured force does not fall within predetermined limits, or if the measured force varies during electrode movement, fusing electrode attachment has occurred.
