I don't remember if I posted this here yet or not, so...

I bought a ColdHeat soldering iron and it came yesterday. When I
tried soldering a couple of 18ga stranded copper wires together,
it failed miserably. It didn't seem to get hot enough to melt the
solder into the strands at all, although it melted about 1.5" of thin
solder.

Tips to get it to work (on the 14ga wire I bought it for) would be
appreciated. Would liquid flux help at all? It seemed like the
carbonized tip got nice and hot but the wire didn't.


It won't. It's the soldering iron Ron Popiel would have invented,
right after his "Pocket Fisherman" It's a cheap attempt at resistance
soldering that just doesn't work on anything thicker than 24 AWG.
