But I can't seem to get the cable to absorb the solder. I'm guessing it has some sort of coating on it that prevents the flux from adhering to the surface. Any ideas?
NB*
Stainless steel is difficult to solder at low temperatures.. [easier, Zn coated cables]
Welding supply shops have what is the lowest temperature stuff.
* But the metal cleaning and fluxing is the part to first pay attention to..
Map/propane torch may make the hotter heat needed for the job.
then it is probably best to solder the cable in the region that is to be cut,
then install the cable.. then cut it.
