What tip should I be using to solder wires together? (lemmy.fmhy.ml)

Pretty basic question but I am struggling to find the words to get the correct search result. The soldering iron I bought came with very narrow tips that I think are supposed to be used for circuit boards and components.

When I attempt to solder lines from a USB cord together the line never gets warm enough.

I remember in the past soldering copper lines together from an appliance with no issue so I don't think I'm doing anything wrong in terms of technique but who knows?

The temperature is set too low. The solder should melt almost instantly when applied to the tip if the iron is set to 350°C.

Those fine point conical tips that typically come with soldering irons are terrible. Get a 2-3mm chisel tip, that will be suitable for most soldering jobs.
