1.- Increase of current will get similar effect with extending time in definite range.
2.- "Pre-fusion current" mustn't be bigger than "Fusion current".
3.- Do not modify value of "Fusion push".
4.- Best to change value of "Push speed" after selecting current usually.
NOTA:
1) Optimization of arc parameter is effective only when arc electrode is well.
2) Fusion loss displayed on screen is of reference only when arc parameter is well and
spliced fibers physical parameter is accordant.
7.4.2 Optimization of MM fibers arc parameter
Optimization of MM fiber arc parameter is different with SM fiber. The relation
between selection of MM fiber arc parameter and fusion loss is undemanding. If process
of splicing is smooth and splice spot is symmetrical, then loss is satisfied, and you
needn't to test fusion loss.
Following are general principles of optimization of arc parameter when splicing
MM fiber:
1.- The value of "Pre-fusion current" mustn't be bigger than the value of "Fusion
current".
2.- The value of "Pre-fusion time" must bigger than splicing SM fiber.
The possible questions and measures are as follows:
1.- There is bubble when splicing.
Solution:
2.- Fusion is insufficient and the light string is broken in the center of fiber.
Solution:
3.- fiber's splicing spot becomes smaller.
Solution:
NOTE:
MM fiber fusion program uses special arc mode. It is normal that screen
menu shakes or you can hear "pa pa" when splicing.

Increase value of "Pre-fusion time", then try to decrease value of
"Fusion current" if it is insufficient.
Increase value of "Fusion time" or decrease value of "Fusion
current".
Try to decrease value of "Pre-fusion current" or value of "Fusion
current".
