Hello.
Around the year 2000, when I first got into building guitars, I bought a spool of solder. That solder lasted me until January of 2021, when I decided that I might try building a pedal kit. I have since gone through another spool of solder.
When I bought the first solder re-up in January, I also got a finer tip for my iron, which is a simple 5-40W Weller. In addition to going through 50g of solder since then, I think I also killed the tip? I went to tin it last night and found that it was broken off like a pencil lead.
Is this common? I've never really used a point this fine before and I'm wondering if I'm doing something wrong or if this just happens. It was a genuine Weller tip, and I generally try to keep it tinned and clean. I don't do anything weird with it. I still have the chisel tip that came with it, and still use that for heavier duty stuff like soldering to the back of pots in guitars, so the fine tip is only ever used on PCBs. This iron doesn't have a thermostat or fancy temperature control, but it does have a knob numbered 1-5, and I usually run it at about 3.5.
Is this normal?
