Hi guys,
I've an American Beauty 150W soldering iron with me which I had purchased few years back but only I used it for the first time yesterday.
I do know about tip tinning. So I heated the iron and applied a 60/40 Pb-Sn and tinned it. But after doing the soldering job for like 2-3 mins even though I used damp sponge it started to turn black and refused to accept solder any more. It started forming beads and wouldn't stick. I couldn't remove it no matter how many times I tried to wipe with the sponge. I had tried using Goot BS-15 acid based ZnCl2 flux. But it just made things worse.
Finally, after some googling saw a video on Youtube and I tried Rosin flux, paper damp cloth instead of sponge and 60/40 lead as per the video. And this time used a power cord with switch to turn off the iron once it was just hot enough to melt the solder and managed to get it like in the picture.
So, my questions are:
1. How can I remove those black spots that still refuse to go away, though I know it wouldn't affect my soldering much? Also I haven't sanded this portion.
2. I've the following type of leads with me:
- non flux core 60/40 lead-tin soldering lead (Its thin and I usually use this with my Weller WP35). Used for tinning
- Weller Radiolot Sn60Pb40 Flux 362 multicore with flux
- Sn-Pb-Ag soldering lead with silver. After using this things turned nasty with the iron.
Am I using the right lead for this high powered iron ?
Thanks. Sorry, for making it long. But I felt I need to explain what process I had followed.
