Ok, I had some time last weekend and did some testing, having obtained some new solder. I dug out my old soldering iron, which I retired as the cable was getting too short (shortened by me a couple of times due to heat damage).

I cleaned my newer and old irons off, and tried both. I found my soldering improved, whichever solder I used with the older iron. I suspect it produces more heat. I’ll just have to use it with an extension! I’m also toying with getting separate flux. The solder is supposed to have a core of it. Is it worth getting a separate tub of flux as well?
