I did not see anything like what you said in that article. Plus writers are like A-Holes, they all have opinions and bias. Being a writer doesn't make them right.

Solder or crimp ??

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.

No fair quoting the actual company! We can only vaguely argue, here.

Just because Anderson (who makes the connectors) gives specific instructions does not mean anyone has to follow them.

If I flame you, would that return us to normal usenet mode?

Flame your Anderson connector.
btw: what's the ampere rating?

Don't have one. I do crimps for heating and AC work. So terminals for .250 push ons, about as big as I get. Usually 16 gage stranded.

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).
They don't need to be machines. Hand crimpers work fine for smaller connectors. The ratcheting type are best.
Sure but adding solder doesn't solve anything if the crimp is good.

The crimp forms an air (moisture) tight seal. Solder doesn't add anything and will cause wires to break.

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

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.

So is crimping.
It does change both.

True. Both can be easily screwed up. All those pins in a D-connector are crimped and I've seen 'em last decades. OTOH, I'll solder the 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.
