AFL ELCT2-20A Fusion Splicer Replacement Electrodes | FSM-18/60/70S/80S/70R/19S/19R Compatible

AFL ELCT2-20A Fusion Splicer Replacement Electrodes – FSM-18 / FSM-60 / FSM-70S / FSM-80S / FSM-70R / FSM-19S / FSM-19R

Electrodes are the most frequently replaced consumable in any fusion splicer — and using the right electrodes is critical to splice quality, arc stability, and splicer longevity. The AFL ELCT2-20A is the OEM-compatible replacement electrode set for AFL FuseConnect and Fujikura-platform fusion splicers including the FSM-18, FSM-60, FSM-70S, FSM-80S, FSM-70R, FSM-19S, and FSM-19R.

When your splicer starts showing high splice loss, arc instability, or frequent arc calibration failures, worn electrodes are almost always the cause. Replacing with fresh ELCT2-20A electrodes restores arc performance, reduces splice loss, and extends the life of your splicer — typically recommended every 3,000–5,000 arc discharges depending on operating conditions.

• Broad Model Compatibility: One part number covers 7 AFL/Fujikura splicer models — ideal for teams running mixed fleets

When to Replace Your Fusion Splicer Electrodes

AFL recommends replacing electrodes every 3,000–5,000 arc discharges under normal operating conditions. Replace sooner if you observe any of the following:

• Increasing average splice loss despite proper fiber preparation
• Frequent arc calibration failures or unstable arc discharge
• Visible electrode tip erosion, pitting, or asymmetric wear
• Splicer error messages related to arc power or electrode condition
• Inconsistent splice results on fibers that previously spliced well

How to Replace ELCT2-20A Electrodes

Electrode replacement on AFL FSM-series splicers is a straightforward field procedure. Open the wind protector, remove the V-groove cover, and carefully extract the worn electrodes using the electrode removal tool. Insert the new ELCT2-20A electrodes, ensure they are fully seated, and run the splicer’s built-in arc calibration routine before resuming splicing. Always handle electrodes by the body — never touch the tips.

Frequently Asked Questions

Q: Are ELCT2-20A electrodes compatible with Fujikura splicers as well as AFL splicers?
A: Yes. AFL fusion splicers are built on the Fujikura platform. The ELCT2-20A electrodes are compatible with both AFL-branded and Fujikura-branded versions of the FSM-18, FSM-60, FSM-70S, FSM-80S, FSM-70R, FSM-19S, and FSM-19R splicers.

Q: How often should I replace the electrodes on my FSM-60 or FSM-70S?
A: AFL recommends replacing electrodes every 3,000–5,000 arc discharges. Most splicers display an arc count in the maintenance menu. If you notice increasing splice loss, arc instability, or calibration failures before reaching this interval, replace the electrodes immediately.

Q: Why do electrodes wear out and affect splice quality?
A: Fusion splicer electrodes erode gradually with each arc discharge due to the extreme temperatures involved (over 2,000°C). As the tungsten tips erode, the arc becomes asymmetric and unstable, leading to higher splice loss, poor fusion, and inconsistent results. Fresh electrodes restore the symmetric, stable arc needed for low-loss splices.

Q: Do I need to run arc calibration after replacing electrodes?
A: Yes. After installing new ELCT2-20A electrodes, always run the splicer’s arc calibration (arc check) routine before resuming splicing. This allows the splicer to characterize the new electrodes and optimize arc power for your current environment.

Q: Are these electrodes covered by a warranty?
A: Fusion splicer electrodes are consumable items and are not covered by a product warranty — this is standard across all brands and suppliers.
