Fusion Splicer Maintenance: Essential Care Tips

A fiber optic fusion splicer is a precision instrument in modern communication network construction. Its maintenance directly affects splicing quality, equipment lifespan, and project costs. Especially for advanced 2025 models like the Comptyco AUA-70F, L-90C, A-5, and FS-60E, proper maintenance not only ensures ultra-low loss splicing below 0.02dB but also significantly extends the equipment's service life. This guide provides a comprehensive, actionable maintenance plan.

Daily Maintenance: The Foundation for Optimal Equipment Condition

Cleaning Procedures: Mandatory Daily Tasks

1. V-Groove Cleaning (Must be performed after each use)

   • Gently sweep the V-groove 3-5 times with a dedicated cleaning stick.

   • For the flip-style structure of the L-90C, ensure the clamp is fully open before cleaning.

   • Check for residual adhesive particles or debris; use compressed air if necessary.

2. Electrode Cleaning and Inspection

   • Clean with an electrode cleaning rod every 50 splices.

   • Inspect electrode tips for symmetry and absence of oxidation (6-motor models like the AUA-70F are particularly sensitive to electrode condition).

   • Immediately adjust or replace if abnormal electrode spacing or rounded tips are found.

3. Screen and Casing Cleaning

   • Clean the 5-inch touchscreen with a microfiber cloth.

   • Avoid spraying alcohol directly on the keys of models with physical buttons like the FS-60E.

4. Fiber Clamp Maintenance

   • Regularly check if the spring tension is normal.

   • For the flip mechanism of the L-90C, add a minimal amount of precision instrument lubricant monthly.

Weekly Deep Maintenance

1. Optical System Calibration Check

   • Test system accuracy using standard calibration fiber.

   • Check if the camera focus is clear (especially for touchscreen models like the A-5, where display clarity directly impacts judgment).

2. Heater Cleaning

   • Remove residual heat-shrink sleeve fragments from the heating slot.

   • Test if heating time is normal (standard should remain within 25-35 seconds).

Preventive Maintenance Schedule

Detailed Maintenance of Key Components

1. Electrode Management: The Core of Splicing Quality

Replacement Criteria:

• Must be replaced every 1500-2000 splices.

• Replace immediately if:

  • Splicing loss consistently exceeds 0.05dB.

  • Electrode tip shows significant wear (increase in diameter 0.2mm).

  • Arc is unstable or requires increased arc strength.

Replacement Steps (for 6-motor models):

1. Select "Electrode Replacement" mode in the menu.

2. Loosen the fixing screw with a dedicated tool.

3. Install the new electrode, ensuring correct positioning.

4. Perform automatic electrode gap calibration.

5. Conduct a test splice to verify performance.

2. Battery System Maintenance: Ensuring On-Site Reliability

Lithium Battery Care (especially for A-5 and FS-60E):

• Avoid complete discharge: charge when remaining capacity is 20%.

• Long-term storage: maintain 50% charge, perform a charge/discharge cycle every 3 months.

• Temperature management: do not charge in environments below 0°C or above 45°C.

• Use the original charger: avoid damaging the battery management circuit with unstable voltage.

Battery Life Optimization Tips:

• Reduce screen brightness (can save up to 30% power).

• Turn off unused functions (e.g., Wi-Fi, Bluetooth).

• Use sleep mode appropriately.

3. Optical System Care: Ensuring Precise Focus

Camera and Lens Maintenance:

• Clean the lens monthly with a lens pen.

• Avoid changing fiber in dusty environments.

• Regularly check if the autofocus function is working properly.

Microscope Calibration:

• Calibrate magnification quarterly using standard fiber.

• Ensure accurate XY-axis display, especially for high-precision models like the AUA-70F.

Seasonal Maintenance Guide

Summer High-Temperature Environments (35°C) Key Points

1. Overheat Protection: Do not exceed 30 consecutive splices; allow the equipment to rest and cool down.

2. Battery Management: Avoid direct sunlight; high temperatures permanently reduce battery capacity.

3. Humidity Control: Use desiccant to keep the equipment interior dry.

Winter Low-Temperature Environments (<5°C) Key Points

1. Preheating Requirement: Wait 5-10 minutes after powering on for internal temperature to stabilize.

2. Battery Insulation: Battery capacity decreases by 40% at low temperatures; keep spare batteries warm.

3. Electrode Adaptation: May require 10-15% increase in arc strength at low temperatures.

Dusty/Sandy Environment Maintenance

1. Dust Prevention: Cover with a dust cover during breaks between uses.

2. Increased Cleaning Frequency: Double the V-groove cleaning frequency.

3. Seal Inspection: Regularly inspect sealing strips at equipment seams.

Troubleshooting and Diagnostics

Common Problems - Quick Solutions

Problem 1: Sudden Increase in Splicing Loss

• Check electrode life (85% likely cause).

• Clean V-grooves and fiber clamps.

• Verify fiber cleave quality.

Problem 2: Equipment Won't Start or Suddenly Shuts Down

• Check battery contacts (common issue with A-5 and FS-60E).

• Test power adapter output.

• Reset system (refer to user manual).

Problem 3: Abnormal Screen Display

• Restart the device.

• Check cable connections (especially for models with physical buttons like L-90C and FS-60E).

• If problem persists, the touchscreen assembly may need replacement.

Problem 4: Heater Not Working or Heating Unevenly

• Clean foreign objects from the heating slot.

• Check heater resistance value.

• Test temperature sensor.
