Reason
Solution
Core Axial Offset
Dust on V-groove or fiber
holder.
Clean V-groove and fiber
holder.
Core Angle Error
Dust on V-groove or fiber
holder.
Clean V-groove and fiber
holder.
Bad fiber end-face quality.
Check if fiber cleaver is
well-conditioned.
Core Curve
Bad fiber end-face quality.
Check if fiber cleaver is
well-conditioned.
Prefuse power is too low or
prefuse time is too short.
Increase [Preheat Arc Value]
and/or [Preheat Arc Time].
MFD Mismatch
Arc power is too low.
Increase [Arc Power] and/or
[Arc Time].
Combustion
Bad fiber end-face quality.
Check if fiber cleaver is
well-conditioned.
Dust still presents after
cleaning fiber or cleaning
arc.
Clean fiber thoroughly or
increase [Clean Arc Time].
Bubbles
Bad fiber end-face quality.
Check if fiber cleaver is
well-conditioned.
Prefuse power is too low or
prefuse time is too short.
Increase [Preheat Arc Value]
and/or [Preheat Arc Time].
Separation
Fiber propelling is too less.
Perform [Motor Calibration].
Prefuse power is too high
or prefuse time is too long.
Decrease [Preheat Arc Value]
and/or [Preheat Arc Time].
Fat
Fiber propelling is too
much.
Decrease [Overlap] and
perform [Motor Calibration].
