I need to wire in some new electronic toys on our boat. So I am in the market for a soldering iron, I have no idea what to be looking for. So what does oppo recommend? I’m not looking to spend a lot, but I don’t want to get some cheap crap that barely works.

Don’t solder on a boat. Use crimp connections. Marine electrical guidelines actually say you cannot solder as your sole electrical connection except on certain size battery lugs.

Counterargument - crimp connections in moist air would be not so good. Even if he heat-shrinks afterward, the solder connection is superior.

Seconded. And soldering *gun*, not iron for wiring things in. $40 later, taken care of.

+1 for a weller iron. Use heat shrink and or good tape (3M super 33+) for anything on your boat.

I’m assuming he’s thinking fire hazard, sump fumes, etc. etc. Bring a fan, I believe you’d be fine, as you’d not tend to have much of anything over auto-ignite temperature and certainly no sparks - except maybe in the switch of a soldering gun.

USCG and NMEA say crimp and shrink is best.

Hmmm...good to know. Guess I’ll go get some connectors and a crimper instead. (might still get a soldering just because lol)

I re-wired my entire boat last season, a ‘69 Chris Craft. Used only high quality crimp and heat shrink.

Don’t skimp and buy a cheap crimper either, I highly recommend a ratcheting one as it makes it easier to provide consistent crimps with less practice.

In my experience, the salt water dries and cracks the solder a lot faster than the surrounding copper wire.

No... In my experience crimping is just better; when done properly. In both auto and marine.

This is a good bang for the buck iron with cheap and durable tips and a good heat supply:
I have a bunch of soldering certs, and most of the irons I use tend to be prohibitively expensive for home use. So that is the one I have at home. I don’t need a $600 iron that takes $20 tips.

I’m OK with either. Most of my soldering has been with a gun, but recently I’ve been using an iron... apart from the fact that it’s a cheap piece of crap it’s fairly nice to use.

+1 for crimp and heat shrink. I worked at a marina for 8 years, this is what we did for electrical connections in nearly every application. On a related note, I miss having access to that parts room....
What kind of boat?

You can also get gel filled connectors to minimize corrosion. Do not solder.

We just bought it a month ago. We plan on taking it out on the big lakes (Michigan, Superior) so I bought a marine radio and a chartplotter that need to be installed

Interesting. I guess I’ve just been traumatized by too many bad crimps and stress damage to wires.

I wonder if different solders react differently. I could definitely see a high zinc solder pitting out, but I would’ve expected the dissimilar metals present in a crimp to be just as much at issue or more. I imagine a good silver solder would be superior to crimp corrosion-wise, but since it’s hard to make people use it...

Bad crimps are bad; stress reliefs on wires, good.
I do a lot of low voltage at work, I’ve seen some shit.

I’m guessing the biggest reason outside of metallurgy control for crimps to be code is reproducibility. It’s probably easier to ensure that acceptable crimps come through than good solder - since the range of possible “LOOK I SOLDURD ET” joints can be a lot wider.
As long as he’s sealing whatever the end product is and actually knows how to solder, I don’t imagine it would matter too much either way. Between a partly naked crimp and a partly naked solder, solder may or may not resist corrosion better, but it at least is harder to get away with not sealing - which is probably what drives the sense that solder is better.
In either case, a bad seal (like on some trailers I’ve seen) leads to misery.

I agree with that.

Given the marine application, you may also consider these:
https://www.amazon.com/Shrink-Solder-Sleeve-Crimpless-Connectors/dp/B01M1032A7
You put the wires in both sides, and heat it up. The sleeve shrinks, adhesive sets and secures, and the solder bead melts all in one step. A light tinning is recommended.

For just doing basic wiring in vehicles I love these little butane soldering irons. I definitely wouldn’t use them on any sensitive electronic components but for basic wiring they are perfect.

Physics of crimping. They say “The result is cold-welded, gas-tight junctions between the strands and the crimp connector.”

See my response link to oovoo. “The result is cold-welded, gas-tight junctions between the strands and the crimp connector.”
And yeah, they assume proper tools and technique is used.

I’ve heard that crimps are superior to solder joints, but it seems counter-intuitive. How can a crimp connection be better than a solid one? Does the act of heating up the wire make it a weak point?

I believe it has to do with the conductivity of the solder. Not sure though. I only use solder on audio stuff and circuit boards (obv).
