Electronic – Could unwanted magnetism be part of the soldering problem

soldering

First off, I'm already resigned to the fact that I am a failure at soldering. (hours of research into dozens of website/youtube how-tos, 4 different soldering irons (albeit inexpensive), 9 or 10 different tips, fluctuating flux amounts, 3 different brands of solder, innumerable attempted techniques, 2 or 3 permanent tiny scars from sub-dermal blistering, and a small pile of charred electronics had, some months ago, broken my will and led to my surrender). But I'm still left with an unproven theory that others here might help confirm or reject. Being that, when faced with being placed onto a targeted location, the solder–after assuming a spherical shape–would, at times, refuse to separate from the iron's tip or, more often, flee the area, rolling the length of the workspace, around obstacles, up walls, or–I imagine–down entire city blocks until I would decide to break off the chase and simply create a whole new obstinate silvery blob, could it be that I had inadvertently magnetized the soldering tip by storing it next to a battery or some other atmospheric anomaly and thereby causing it to disrupt the normal soldering process and ultimately revealing it to be the cause of my circuitrous disability? While I eagerly await your replies I will click on the "unwanted magnetic induction" question to the right that I just now discovered. My gratitude to the team, –smf

Adding to all previous comments, my experience is to avoid cheap (hobbyist) irons altogether as they do not reach a high enough temperature and cannot maintain that temperature when the tip is presented to the job very well. A tip that is clean and tinned (but not running with solder) should be presented to heat the joint slightly prior to the solder being applied and if the iron is hot enough and the component and board are clean, the solder will flow and it should be possible to do it in around a second. There should be no balling at all. My advice is to invest in a Weller or similar make iron if you are doing a lot of soldering and avoid the cheap ones altogether.
