I bought a new iron - 60W - because none of mine seemed hot enough. Just a little old fashioned rugged electronic organ amp board to work on. Now I find it won't tin the tip. And makes a dubious job of soldering a component in and I think it is because of that. Generally heat gets transferred from the tip into the job via the solder on the tip, that's what I've always thought. So if it won't tin and there's no solder on it you're beat before you start. And though it gets hotter in the hand than any iron I've ever had the tip seems very cool. Nothing's happening on the board. When unsoldering the solder isn't melting. But it is also the most pointed tip I've ever had. It'd seem to me perhaps pointed tips transfer less heat than a wider tip would. Yes? No? So I google for help/info and I find people saying 'file the tip', and others saying 'never file the tip' and some saying 'scratch the tip' and others saying 'don't', and some saying use baker's flux on it and others saying 'never use Bakers flux.. it's plumbers flux, it'll kill your board' and some saying use on 1mm flux cored and others saying use 3.2mm flux cored and some saying don't use flux cored, use flux and solder... And some saying that's a bad iron. Some irons are just bad. And some saying that's a bad tip - tips are specially cleverly made, not just lumps of iron and that tip ain't. and that's without getting into the heat of the thing. or the tip shape. Anyone got all the clues so's I can get up to speed in a hurry? I've got four trannies to solder in and the quicker the better.
