Directions also say to add flux, Is it in fact Rosin Core?.** A: If the roll of solder you received from this page does not say: "44" ROSIN CORE - on the right side, in the yellow stripe, then it is not the solder you paid for. I am 66 years old, learned to solder electronic components by having to complete a full 16 hour course during my electronics training in the USAF back when I had just hit 18. ALL the solder provided to work on the aviation and aerospace gear I dealt with while in service was Kester "44" with 60/40 ratio. PERIOD. I still have a few empty spools from back then. The only difference is they were metal spools back then, and the label was a paint-printed like a soda can. BUT the label looked the same (1971-75) then as it does now. It quite definitely says that is it rosin cored. If the label is missing (can happen these days with printed paper labels and plastic spools that don't accept glue well) you can test for rosin core by cutting off some of the tip (to remove the seal your solder iron left there) and if you then heat the solder with an under-temp iron, the rosin should "bubble" out the open end before the lead/tin melts. **Q: does anyone know how many meters does this comes with?** A: The length is approximately between 380 to 400 feet or 115.8 to 121.9 meters per pound. **Q: Would you use this solder for audio kit circuit boards like the wave "http://www.amazon.com/wave-analog-driven-spring-reverb/dp/b00r8jfblo/ref=sr_1_1"** A: Kester SN60-/PB40 solder or Kester SN63/PB37 solder, 44 rosin core will both work well for audio and circuit board applications. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality over price here it might cost you more than most other solders but it delivers *by J***L on July 24, 2025* What can I say about this product well there's a reason that they're one of the best in the world because they put out great products they're solder is multiple at low or high temperatures withstands high temperatures and high currents and withstands the test of time not like some solders that as soon as you put it to your tip starts to burn off immediately not this stuff you can actually have it set on there and work with it and do multiple little sections of soldering before having to wick it off Great product can't say enough well worth its price ### ⭐⭐⭐⭐⭐ best solder on market? *by G***Y on March 25, 2026* this is the best solder i have ever used. the flux rate of 3% is better than the 1.8% you'll find here.
