I use, and have used for years, Kester 44 Rosin Flux solder, #66/44, 1.2mm (.050). It flows nicely, has an ample amount of flux for washing away oxides and keeping the tip clean, and a 1lb spool will last you for several years. I like the .050 size - it's good for everything from radio system wiring all the way up to 10AWG battery wiring, assuming you're using a decent 45W 800-850 degree F or hotter iron. Just be sure to NOT inhale the vapors and wash your hands afterwards. Good stuff.

Thanks a lot ! best instruction video I have seen you make it look easy

Excellent instruction!

@tbhollywood - You bet. Thanks for watching.

Silver-bearing solder (like 62/36/2) is prevalent with audiophiles (audio system nuts). Although it does have some marginally better conductivity, slightly higher tensile strength, and can help protect silver-plated terminals from oxidation, the benefits over good 'ol 60/40 tin/lead activated rosin for RC hobby application is negligible. It does have a lower melting point than tin/lead so if you have a lower wattage iron and want to go lead-free it's a better choice.

Great job!! Thank you, this has always been a problem for me, :-)

[@NateFrias]

Thank you for your help :) I think im ready to start soldering.. doesnt seem to bad now

[@jp00000420]

Very informative.

[@chadkraig61]

YES, thank you

If you use Rosin Core solder, the flux is in the core, so no external or additional flux is needed. Some people use solid core and use rosin flux. If so, apply flux to each connection (wire or terminal) prior to soldering. Apply heat and melt the flux onto the surface either before applying the solder or during. Just be sure NOT to use acid flux. Acid flux and its vapors are corrosive to electrical components. Always use rosin or water soluble flux products. Rosin is still most popular.

everywhere I look for solder it's all lead free. does this work or should I keep looking?

[@blue03r6]

and what about silver-bearing solder?
