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.
TIA
