How to solder thick wires?
If you're doing this outdoors, you'll probably need at least 100 watts.
Butt connectors scare me. It takes some practice, but you can do decent solder with the torch. Ive used it on battery cables before also... Like I said, you just have to be VERY careful you dont heat it to the point that it gets red hot and starts melting everything and making the copper brittle.
Otherwise...get a high wattage iron like mentioned above. Or an actual solder "gun"...
