Flex Cable ??????

[MAMBA2200]

ok i have tried to solder the end of a cable that i got from kintec its a .187 cable and i have tried every kind of solder and heat and the solder just rolls off what am i doing wrong

Flux and wire brush?

clean it with anything else?

I wire brush the area to be soldered for minutes on end. I then clean the cable AND the inside of the stub shaft with break cleaner and let dry for a few minutes. I then add flux paste, assemble, tear apart and more flux as needed. Pull apart again, cut small piece of solder and stick in shaft. Assemble, heat and push on flex until solder melts and bond is made.

If you get it to hot the solder won't work.

im doing the coupler end and have tried the methods mentioned and different temps im confused

[Heaving Earth]

Egneg is right, and once you've gotten it too hot, it's hard to get the solder to take even after its cooled off and reheated. Try sanding it well with 80 grit, then clean in thinner. Then flux and small amounts of heat at a time testing with solder until it starts to take

Don't solder it. There is no point in doing it.

I've been running nitro and electrics for 20 years and have never soldered the coupler end of a flex cable and have never had one break on me in that location. Don't waste your time- just grind a slight taper for ease of insertion and forget about it.
