How to replacing Electrodes for Sumitomo Fusion Splicer

The electrodes will typically need replacing after approximately 1,000 discharges. If the number of arc discharge exceeds 1,000 times, Arc Count shown on the screen (refer to page 25) will be highlighted in red for warning. The electrode tip is extremely sharp. Handle with great care.

8: Plug the power cord into the power module and turn on the power to condition the electrodes.
Ensure that the new electrode is fully inserted with the plastic button against the cover plate. Failure to do so may cause splicer malfunction or to low splice performance.An electrode tip is extremely sharp. Handle with care.


  • Be sure to turn off the splicer and unplug the power cord or remove the battery before replacing the electrodes.
  • Discard the old electrodes properly.
