The solder for electrical joints is not like the solder for other things. It
has a rosin core. Most others are either solid, to be used with an externally
applied flux, or acid core
You can buy rosin core most places that sell
solder. I use a two speed Weller gun and rosin core solder from Radio Shack if
I'm only doing a few joints,
otherwise I use a very small iron that stays hot
as long as its plugged in. You don't have to wait for it to heat each time.
The solder I have is about 1/16 in. in diameter. I find that it takes the gun
a few seconds to heat enough to melt the solder. When the solder melts against
the gun tip,
let it run onto the joint so that it will help conduct heat to
the joint. To put a connector on the end of a no 22 wire only takes about 1
minute. Of course, if the piece is
large, it will conduct the heat away from
the joint and will take longer to get it up to temperature. I have had to use
an Ox-Acetelene tourch to solder large copper pieces
There are other, higher
melting solders such as silver solder which melts almost at the melting point
of brass. my solder is a 60/40 mix of lead and tin. Pure tin solder has a
somewhat higher melting point so would be a little slower to melt, but not
very much.

Subject: [TR] soldering
On one of the
recent posts I read where someone mentioned not having good luck
soldering
electrical connections.
I have been having an awful time soldering.
My
soldering iron is a Weller 140/100 watt and the solder I'm using is the
same
solder I used for soldering plumbing joints.
It takes a long time to get
the
solder to melt even if i place the soldering gun directly on the solder
itself. And its basically impossible to get the joint hot enough to melt the
solder as the directions tell you to do. It's been the most frustrating thing
I've had to try to learn.
Do I need a larger soldering iron or do I need
different solder? Is there a solder specifically for electrical connections
in cars that has a lower melting point?
thanks!
