Be careful not to pull the wiring out when replacing the electrode bars.
Clean the new electrode bar with a clean swab or dust-free cloth soaked in
alcohol, then install to the fusion splicer, place the electrode cover and tighten
screws.
It is strongly recommended that after replacing the electrode, electrode stabilize
and ARC calibration should be done (operations are described below), or else
splicing loss and strength cannot be assured.
