I'm never settling for cheap solder again *by R***P on March 16, 2024* I've been using cheap generic solder for a while, and I thought my soldering technique was poor because I kept getting cold solder joints and had to use a lot of flux. This stuff flows effortlessly and leaves nice, strong, shiny connections. I did a quick solder job and every solder joint on the PCB and my wire connections looked flawless on the first attempt, I didn't even need additional flux. I threw away all my cheap solder when I was done and I'm strictly using Kester solder from now on. ## Frequently Bought Together - Kester solder 44" Rosin Core #66/44 .8mm 1 lb.
