I think I suggested that about a week ago!

Sounds good, if you plan on burning all the plastic around the
soldering area I'm considering with wind included...pretty messy
sometimes..


Not if you use your brain just a TINY bit.

You fire it up, let it heat to the proper useable temperature and
the SHUT THE FLAME OFF before you get near the plastic parts.
Should be good
for one or two joints before the wind cools it off too much.
OR
The little catalytic flame only blows in one direction; once you
figure that out, you should be able to point it AWAY from the
meltable parts........and once it is up to temp. and you turn the
"flame" down to
a maintenance level, there isn't that much heat coming out anyway.
OR
You could continue to whine over nothing.




The Portasol is very controllable, I never melted anything other
than solder with it.
All you need is some soldering skills and some common sense when
using it.

A good flux is often handy too.

The strands in vehicle wiring are rarely tin plated and usually
oxidised, the flux in cored solder just makes a mess so I keep a tub
of active plumbers flux ready to hand.

Someone else mentioned the risk of vibration to soldered joints -
heat shrink sleeve reduces this risk significantly.




Rosin Flux Soldering Paste is what you need.


It doesn't work - it just burns on as an impenetrable lacquer so you
have to scrape all the strands with a knife blade before you can carry
on and do the job properly with an active flux. If the solder takes on
any of the strands you can't easily scrape them so you then have to
cut the ruined strands off and start all over again!




soldering with an acid flux is OK *IF* you clean ALL the flux off
afterwards. (very iffy...)

Otherwise,the acid eventually eats thru the wire enough that vibration
breaks it.

BTW,some rosin fluxes are more active than others.

I wonder if you first cleaned the wires with Tarn-X,then soldered with
rosin flux,if that would be better?

Capillary action will pull acid up the insulation when heated and down the
road the joint will fail.
