SOunds too good to be true.

I've seen too many "cold" solder joints and a tool like this does not provide enough heat transfer in the time duration that they promote.

Notice they mention the tip temperature heats and cools quickly. Good solder joints require the wire/connector/circuit board pad be hot enough for the solder to flow and bond without voids. Cold joints are difficult to see with the naked eye.

Spend your $20.00 elsewhere.

I thought you were not suposed to solder connections on a boat?? Not on my boat!!!

Can't last long with 2 AA battery's. Better bet would be a butane powered versions like this:

I keep it on the boat and use all the time. It's very convenient. Careful using it in the bilge areas if it's an inboard Gas boat.

The butane types work well for small terminations.

I still don't agree with soldering wires /connectors in a marine environment.

I rarely solder anything on the boat..... really just want it for the toolbox.

As for the batteries, it uses 4 AA batteries and the WEBsite says it will solder 700 points on one batter set.

It sounds like one of those 'too good to be true' things...

It sure is tempting though, I've managed to burn myself more than once with my butane soldering iron. And you've got to be REALLY careful where you set it down.

If I saw the same ad as you the guy solders a connection and then almost immediately touches the tip with his fingers. I figure one of three possibilities;

1. It actually works
2. The guy's got a really HIGH pain threshold
3. The whole things a camera trick

But tempting never the less...it's 'only' 20 bucks...

Is that all that's keeping you from getting the production line going for the QCCORH?

Hey, it's only 20 bucks. Try it and let us know how it works.

These types of soldering irons do work...they've been around for years now using rechargeable nicad batteries. This one looks like a cheap knock off of the semi pro ones. I'd save your money and just buy a reliable pro model for maybe twice the price.

Ok, silly question from a new guy here. After reading the replies above, I notice a few of you mention that you do NOT solder wiring on the boat. Why is that? I have been slowly replacing/rewiring the twisted mess of wires on my old boat, and have been soldering all the ends on the wire, instead of just crimping.

In my little mind, I thought the solder would give me a better connection than just by crimping. Plus, I figured there would be less chance of corrosion becoming a problem.

Somebody help me out here. Should I not be soldering??

Stick,

You're doing just fine, don't change anything.

Stick,

Crimping is the the way to go on the boat. The solder creates a rigid joint that will not flex. Think about it this way, you do not use solid wire on a boat, you use stranded wire because it will flex, with the solder you create solid wire. As the boat moves the wire moves and the stranded wire can move more than the solid wire before it breaks.

Crimping faster, holds better, lasts longer, comes in it's own heat shrink waterproofing (if you buy the correct ones).

Soldering creates bad joints that will eventially fail (as stated above), is a pain in the BUTT to do properly (whihc is VERY important) in the marin environment (windy, wet, no electric often...), takes to long to do.

Get a GOOD crimp tool, buy marine heat shrink crimps of the proper size, done.

Given the average usage of a boat a soldered joint should last about a million years before it becomes so brittle it breaks. What about all the soldered joints in the circuit boards of VHF radios, AM/FM raidios, radars, fish finders, GPS units, engine electronics, etc.? If soldered joints were all that bad when they be using them in those devices?

All of the complaints on soldering are based on the ability of wire movement. Soldering is fine, in any environment, if the wires are properly secured. If you are going to solder, make sure you clean all the flux off, since it's corrosive. I crimp, then solder. Crimp, solder and, heat shrink if you really want bullet proof.

Bottom line, never leave wiring loose. Secure it to something solid with a tie wrap at close intervals. If a wire is loose, I don't care how you've terminated it, it's going to come apart. Electrical tape is not a permanent solution, when it get's hot, the glue fails.

I've put radios into 2 ton type diesel trucks that shake rattle and, roll, I've always soldered the lugs on. I've never had one come apart. Yes the shocks are different from a boat, but what does it say about ride quality if the driver sits on an air ride seat?

Where is that ABYC wiring standards link when we need it.

Don't forget tinned copper wire.
