I made a new video about why I love liquid flux and how much of a difference liquid flux can make to your soldering.
In this video I created a large blob of solder. I used the MG 4884-227G solder that I always use but once I had the solder down I cleaned away all of the flux then reheated the solder to cause it to oxidize. The now dry, oxidized solder is unruly and uncooperative. It blobs up and forms peaks and is just generally nasty.
Then, I bring some of my Kester 186 liquid flux to the party and the solder is reborn.
I just go to Ebay, type in Kester 186, and guy a bottle. 100ml of the stuff will last you for years unless you’re doing a LOT of soldering.
I’ve always used flux paste - do you see better performance with the liquid compared to paste?
I use a squeeze bottle which let’s me put the liquid flux exactly where I want it. I have paste flux on my solder shelf along with borax for silver solder.
