How To: Solder Large Gauge Wire.


Recommended Posts

the crimp compresses them into a single piece.

look at the picture at the top, it looks like a solid piece of metal, not individual strands.

Not sure which picture as the one I saw was soldered. But when I did mine the solder had to go somewhere and it didnt leak out...

I absolutely agree that with proper hydraulic crimping there is no place for solder. If there is, you have done it wrong. Here are a couple of pictures that I took:

Interesting. Wonder what I did wrong then. Dont really have the money to cut one up as they are not cheap.

Not cheap? I buy my lugs for like 50-80 cents and they are pretty solid. Copper or tinned copper.

Those are the terminals I like to use too Daimer.  I dont crimp them though, The ones I get come with Solder plugs that you drop in.  Basically you clamp them in the vice with the hole facing up, Drop in the solder slug, heat the terminal up with the propane torch, Pre strip the wires to the exact depth you need, then once the terminal is HOT and the solder is melted, just slide the wire down inside it and hold it there.  You can keep heating it and feed more solder in at the junction, but with the solder slug, thats really all you need.  Feeding a bit more solder will help seal the end around the terminal, but if you use too much it will suck up the wire and melt the jacket and make the cable stiff for however far it travels up the wire.

For Battery terminals I like these Flag style terminals

flag%20negative%20battery%20terminal%20f

and the solder slugs

Napa%20Solder%20Pellet%20for%201%20gauge

I use Heavy Duty Battery cable heat shrink with Glue inside.  It helps seal the connection and prevents corrosion.
