I give...what is the best way to solder large cables?

[TC]

heat it with a torch and then as you heat it melt a bunch of solder into it until it is full, then take the cable with the insulation stripped off and push it down into the solder

I'd want to tin the wire first and make sure it's fully heated, just pusing the cold copper wire into hot solder will not make a good connection.

Probably a good idea, but I've never had a problem not doing it.

I was going to ask about sticking a cold wire in hot solder. I've only had good luck soldering things that are both heated.

I'm not doubting you, just surprised that it works.

When I soldered the connector on the starter end of my battery cable, I dipped the wire in flux, crimped the end on (to hold it still), heated them both together with a torch, then filled it with solder. After it cools, apply heat shrink.
That method worked great... but next time I won't put as much solder in, because the cable was rigid about an inch and a half back from the connector. heh.

I did some #6 battery cables for the robots, clamped the terminal in the vise, put the wire in it, heated the terminal and the end of the wire with the torch, fed in about half a roll of .030 electronic solder. I suggest the bigger size of rosin core 60/40 solder for this stuff, they make it in 1/16" also.

when i was in high school teacher in electronics class used to scream at us good mechanical connection before soldering

if wire over heats it will just fall apart if solder is onlything holding it together

Yeah, it's a good idea to crimp it first. I'm still looking for an affordable big crimper.

How about this?
That's what I used for 4 and 1/0 cables on my van.
