Electrode replacement
3. Maintenance
Electrodes are worn out or contaminated due to silica glass evaporated during
arc, and the electrode condition changes day by day. To achieve a repetitive and
stable arc for excellent quality splicing, electrodes should be replaced periodically.
Continuing to use the same electrodes may result in high splice losses and poor
splice strength.
On the TYPE-72M12, electrodes typically need replacing after approximately
1,500 arc discharges.
If the number of arc discharge exceeds 1,200, Arc Count on the screen will be
highlighted in yellow for warning, with a message “Electrodes need changing
soon”.
If the number exceeds 1,500 times, a warning message appears every time the
splicer is powered on and until you replace electrodes according to the
replacement procedures described in the next page.
Always replace with Sumitomo genuine electrodes in pairs at a time. Failure to do
so can keep the splicer from maximizing its ability.

Precautions on electrode replacement
• Be sure to turn off the splicer and unplug the AC power code or remove the
battery pack before replacing the electrodes.
• An electrode tip is extremely sharp. Handle with care.
• When handling the electrodes, avoid touching the electrode tips with anything.
• Do not clean the electrode. Doing so may cause unstable arcing performance.
• Discard the old electrodes properly.
