With the proper tools the crimp seems to be the best. After a while the
atoms in the wire and the connector will fuse together somewhat.

If you can not use the proper crimping tool then solder.

Hi,
If properly done. Ever looked at crimped or solder connection under hi
power magnifier?

The way I read the article he's talking about ONLY crimp versus ONLY
solder. Not crimp first then solder, which is what I do if I'm
looking for a belt and suspenders solution. That said, I've read in
the past that a PROPERLY crimped connection does not need to be
soldered, the kind of crimp powerful crimping machines can make in a
manufacturing facility. The crimps I do at home, even with a decent
hand crimper tool, I don't consider the same quality as a factory
crimp. But many of those home crimps have lasted years and years with
no trouble...

WHAT????
Solder will work for a connection that does not move, but for a
connection that moves crimping is more desireable as the wire will not
break as easily.
Crimping is generally more desirable for most electrical connections.

In aircraft wiring it is crimp only - no solder because solder wicking
back the wire stiffens the wire, and any flex gets concentrated at
that point - breaking the wire.

Correct, that's exactly what the article is about.

That said, I've read in

manufacturing facility. The crimps I do at home, even with a decent

crimp. But many of those home crimps have lasted years and years with
no trouble...

A properly crimped connection doesn't need to be soldered if that
joint will never be stressed, if that joint will never be subjected to
moisture or vibration, if that joint will not be subjected to a
corrosive environment, if that joint is in a terminal that solder will
prevent the terminal from seating properly in its' housing, if that
joint...

There are a few more if's but I think you get the point. The biggest
"if" is being properly crimped. Unless it is done under controlled
conditions that will frequently not happen.

In the harnesses I designed for earth moving equipment for about 30
years all connections were crimped and soldered except the joints that
solder would prevent the terminal from seating properly in its'
housing. And that is exactly what I still do at home.

I have a ratcheting type crimp tool and have used low temperature silver
on crimped connectors if I'm worried about moisture wicking into the
stranded wire plus heat shrink that has the hot melt sticky stuff on the
inside. Regular heat shrink tubing makes a good strain relief on the
wire crimped into a connector because it prevents a sharp 90° bend in
the wire crimped into the connector when it's put under stress. The most
important thing, don't nick the wire when you strip the insulation off
of it. ^_^

Am I to believe that the quality of the connectors is sufficient to

Crimping is preferred to soldering.
Just make sure you get a good crimp. Most of their contacts require two
crimps.


Soldering is acceptable but you must absolutely insure you do not splash
any solder on the mating portion of the contacts. Since the contact are
silver plated, solder will degrade the connection.

However, it didn't say anything different from what I said farther

The one thing that was definitely not said was any mention of atoms
fusing. That was why I commented about your smoking habits.

Think of it as arc welding, only a heck of a lot slower.

Oh yea, really why? Arc welding is the melting of metal and making it
flow to join two or more metals.

Where is crimping anywhere like that. Crimping does not change the wire
or crimp.

Your inclusion of truck manufacturers is definitely wrong. I
guarantee that Caterpillar crimps and solders all of the connectors
and terminals except where solder will prevent the terminal from
seating properly in its' housing. Caterpillar builds trucks.

I suspect your list may have included other manufacturers in error.

Per Ashton Crusher:

On my winter bike - equipped with an electric motor - I've got 4 crimped
Anderson connectors and four solder joints.

Over five years, the solder joints have failed twice but the crimped
connectors have given no problems.

OTOH, that's just failure. The efficiency of transmission has got to
be a whole other issue - which I have no clue about.

Again done correctly, the crimp will have almost no differance than a single
piece of wire. The solder will have a very small ammount of resistance.

Probably did not come out the way I want it to, but the crimp will have less
resistance than a soldered joint.

What's your issue? What he said is perfectly correct. Crimping is
better but only if it's done *right*. We often do both (crimp, then
solder) because we don't have the proper tools for all of the
connectors we use. Usually the stuff only has to last a few weeks of
light usage, though. I'd never do it for anything safety related or
has to last decades, though.

Solder will actually cause more problems than it solves (for properly
crimped connectors). Solder will wick up into multi-strand wire and
cause the wire to break at that point, under flex (work hardening).

That said, I've read in
the past that a PROPERLY crimped connection does not need to be
soldered, the kind of crimp powerful crimping machines can make in a

They don't need to be machines. Hand crimpers work fine for smaller
connectors. The ratcheting type are best.

hand crimper tool, I don't consider the same quality as a factory
crimp. But many of those home crimps have lasted years and years with

Sure but adding solder doesn't solve anything if the crimp is good.

The key word in "proper crimp" is "proper". If you can't guarantee
that, solder is good but it will cause other problems. If you're
worried about the connection (or if a fault may cause damage or the
possible loss of life), dump the crappy connectors and crimper and do
it right.

When soldering was mentioned, I was thinking for around # 12 wire or
smaller. I worked around everything from very small wire around # 26 to
some of the 000 sizes. Never soldered anything. Had to use some hydraulic
crimping tools on the larger stuff. Hand tools just would not do a good
job. I doubt anyone would think of soldering the wires that are over 1/4 of
an inch or larger.
There were some ground wires that were cadwelded, but I don't count that as
solder.

The place I worked for had thousands (maybe millions) of crimped or wire nut
connections. Almost never saw a crimp fail except when some dummy tried to
crimp solid wire. A few wire nut connections failed, but I suspect they
were not put on correcctly.

At one time around the house I did solder some of the molex connectors that
used from # 24 to # 12 wire. Not that I wanted to, but because I did not
have the proper crimp tool. Now I have the tools, I don't solder.

lugs to my car or golf cart battery. Big stranded cable crimps are
prone to corrosion, more so than small stranded wire. As always, the
correct crimper is a must. Those Amp pin crimpers can be damned
expensive, but they do the job.

Oh, we just used those for auxiliary contacts, I usually worked with the
350AMP connectors where heating could be significant.

When soldering was mentioned, I was thinking for around # 12 wire or
smaller. I worked around everything from very small wire around # 26 to
some of the 000 sizes. Never soldered anything. Had to use some hydraulic
crimping tools on the larger stuff. Hand tools just would not do a good
job. I doubt anyone would think of soldering the wires that are over 1/4 of
an inch or larger.
There were some ground wires that were cadwelded, but I don't count that as
solder.

The place I worked for had thousands (maybe millions) of crimped or wire nut
connections. Almost never saw a crimp fail except when some dummy tried to
crimp solid wire. A few wire nut connections failed, but I suspect they
were not put on correcctly.

At one time around the house I did solder some of the molex connectors that
used from # 24 to # 12 wire. Not that I wanted to, but because I did not
have the proper crimp tool. Now I have the tools, I don't solder.


I quit soldering connections in the late 70's

In the 30 years I was crimping there were no problems.
(Other than my very first time.)

OTOH: Guys in the shop sometimes soldered and got the contacts
contaminated...and the connector would eventually melt due to the heat.


The only time we used a foot-operated hydraulic crimper was in a nuclear
power plant when we used 300mcm cables.


Normally 4/0 was the max. we'd deal with.

Again, depends on the application. I jes replaced all the battery
cables on my 6V golf cart. Severe corrosion where the stranded heavy
gage cables crimp into the battery lugs necessitated it. The new
one's are the same thing, so will probably encounter the same problem
eventually. I suspect this construction is more about economy than
effectiveness. Why waste money on solder when crimp will do, in the
short term. I helped one lady with a bad golf cart cable. She was
trying to crimp on a new lug, but had no proper crimper. I soldered
it.
