Solder Wire, 63-37 Tin Lead Rosin Core for Electrical Soldering,1.8% Flux Contains(0.8mm/50g)

I've never seen this happen before, rather than melting this somder wire clumps up breaks apart. Eventually you can get it to finally melt and work it how you need... But overall trying to use this solder is more trouble than it's worth

This is the most contaminated solder I've ever seen. It instantly turns black and won't stick to the soldering tip. Had to increase 15 degrees above recommend melting point before it even tried to solidify. if anyone purchased this ,better do like I did and chunk it in the trash . Walmart solder is 20 times better and it's bottom tier. Wish I would have read the reviews before I purchased it.

I did not receive what I ordered, but what I received worked fine for my purposes. For some reason the wire size was not one my welder had rollers for, which was an unexpected problem, but we made it work. I received a solid core wire which is a bummer since now we need to get air tanks, but otherwise the wire is fine.

I do not do a ton of soldering, but enough to go through 25g per year or so.I was running low on my normal solder, so I picked this up.At the same temperature of my iron, this does not flow when my other solder, from Kester, flowed without issue.I had to bump my iron to nearly 450ºC for this to even start to flow. I went through a few inches of this stuff to make sure it wasn't a manufacturing defect at the end of the wire, and unfortunately it wasn't. It also tends to bead up, which makes things even more difficult to flow again because you have to cut it off or just have it sit on your iron for far too long to get things moving again.It does melt eventually, and it may be the solder they describe, but it is not worth your money to waste your time on this stuff. Sorry y'all, but it just doesn't flow well. Save your time and frustration and buy Kester or Weller or MG Chemicals or maybe just from your local store and you'll be better off.

Works as intended.

This solder wire doesn't melt until the iron is super hot. As soon as you start to solder it just clumps up and break off. Sometimes I can get it working ok, but more often than not it's just a pain to work with. I cannot recommend this product.

No complaints, works great with my Weller. Make sure you use a fume extractor or have good ventilation, and be aware that this does have lead in it, so you'll want to wash your hands after use.

This solder melts and flows well. It fuses without additional flux. I found it to be suitable for my use and a great value for electronic soldering.
