The most common parts of a fiber fusion splicer include Electrodes and V-Grooves. Fusion splicers are dependent upon high-quality electrodes to focus that critical arc of electricity. As the electrodes wear from use, electrodes gradually worn and lead to weaker splices and higher splice losses. Cleaning electrode is part of the essential maintenance of fusion splicer and will not restore the performance of the fusion splicer as electrodes need to be replaced.
Always replace fusion splicer electrodes as a pair. For optimal performance, electrodes should also be aligned when they are replaced. This is a tuning process to maximise the performance of your splicer.
1. Electrical welding electrode life is generally about 2000, after a long time the electrode will be oxidized, resulting in the discharge current is too large leaving the splice loss value increases. You can remove the electrodes, medical cotton wool dipped in alcohol to gently wipe and then install the fusion splicer, and discharge cleaned once. If repeated washing, the discharge current is still too large, it shall replace the electrode.
Replace the electrode first remove the protection of the electrode chamber cover, loosen the screws fixed on the electrode, remove the upper electrode. Then release the top wire fixed to the lower electrode, remove the lower electrode. Installation of new electrode opposite action of the demolition order, require two electrode tip clearance: 2.6 ± 0.2mm, with the optical fiber symmetry. Under normal circumstances electrode is not required to be adjusted. Not touch the tip of the electrode in the replacement process, prevent damage, and should avoid the electrodes to fall inside the machine. After replacing the electrode to carry out calibration of the arc position.
Care of the electrode used for a long time, the tip of the electrode will produce sediment discharge poor, then there will be a “hissing” sound, then need to clean the electrode. The recommended the regular welding machine electrodes care that clean the electrode.
2. 4 clean V-shaped groove welding machine tune the core direction of the upper and lower driving range each only tens of microns, slightly foreign body will make the fiber image deviation from the normal position, resulting in normal alignment. At this time the need for timely clean the V-groove:
a. Off the windshield of the welding machine.
b. Open the fiber optic pressure head and the clamping platen.
c. Stick with a cotton swab dipped in anhydrous alcohol (or sharpened toothpick) single wipe in a V-Groove Fiber Aligner.
Note: Avoid using hard objects to clean the V-groove or V-groove on the force, to avoid bad V-groove or V-groove inaccurate, resulting in the instrument can not properly use.
Proper use of Fusion Splicer is to reduce an important guarantee of the optical fiber splice loss and key links. You always should be strictly in accordance with the instructions of the welding machine and operational procedures. And properly set the welding parameters according to the type of fiber (including pre-discharge current, time and the main discharge current, the main discharge time). Do as above, the working life of your fusion splicer certain can be longer.
