Kester 24-6337-8800 50 Activated Rosin Cored Wire Solder Roll, 245 No-Clean, 63/37 Alloy, 0.031 Diameter

This solder is amazing. It really is the best that I have ever used! No more having to use flux on nearly every joint, this stuff flows so well. My only regret is not having been aware of this brand when I started soldering. This is the solder that Ill use 100% of the time now.

Good quality solder for basic electrical project work.

Limited use so far, but did exactly what I needed.

Dont let the slightly higher price scare you away. After the first use, youll understand why is more expensive.

I know its not politically correct to say this but wow - what a relief to get back to a good tin-lead solder vs. the no-Pb stuff I struggled with. Just could not make it work with my controlled temp Weller station. I love this Kester alloy.

Nice size for hand held soldering of wires

Works great for clean copper only. If you have slightly dirty surface you must use a stronger rosin then what is this. I love the option. If this doesnt stick I add a little Flux and clean after I solder. If it a clean surface I just use this and dont clean. Works great this way for.me.

What can you say? Narrow gauge, good for electronics. Ive been using Kester for 50 years, as long as they havent changed the formula it should be fine

If youre like me, you might think youre a noob at soldering. Again and again, I lift pads, make dull joints, and just overall have a crappy, frustrating time doing soldering jobs. Then I took a long hard look at the tools I was using... my iron was fine, a Hakko FX-888D. Probably the best in the business, for a casual home solderer. Next is the solder itself... Lead-free rosin core. Hmmm, could this be the problem? After getting this 63-37 leaded solder, I can most definitively say: yes, lead-free IS the problem. Love the lead. Live the lead. After finishing up a soldering job for the balance plug of a 2S Lipo (FPV quads, if anyone was interested), I looked at the joint and I was wowed at such a good job I did. Or rather, such a good job the leaded solder did. Shiny, flawless, just perfect. Live the lead! Lose the lead-free!

Have been using that brand for years and once my old supply ran out, I got a new roll and it was just as high quality as the old ones.
