my main problem always was how to transmit heat from soldering iron to something that's not solder - knowing how it should look in the end is the most trivial part of it


@zwangseinweisung flux reduces surface tension, so you can heat the solder better

it doesn't increase the contact from soldering iron to non-solder-surfaces.

(also it's really hard to even find solder wire that doesn't already come with flux inside)

@drazraeltod You're right, but I like to think that it works better when I add flux.
