Happy Holidays

I could use the group's help. I've been experimenting with finger (box)
joints using my tablesaw and Freud stacked dado blades.
I've been using a 1/4" stack to dado 1/4" wide, 3/8" high finger joints
through 1/4" plywood. Every cut burns the wood and lets
off some pretty serious smoke and stink. I've tried slow feed and moderate
feed to control the quality of the dado cut and not
overwhelm the motor. Tips of the dado blades getting a rusty color to them
as well. Its not rust as I baby them and keep them
safely stored when not in use.

Is plywood susceptible to burning? Am I killing my saw and blades? Any
advice to cut these joints correctly is greatly appreciated

Here are my tool specs:
TS Craftsman 10" (model 315-228390)
1-1/2 HP induction motor developing (?) up to 3HP
3600 RPM
13 amp

Freud 8" , 12 teeth, stacked dado blade (SD 208)

Happy New Year
