Review: Nice clean solder, melts smooth and doesn’t smell awful - Grabbed this 0.8mm lead-free solder mostly for quick electronics fixes, and honestly it’s better than a lot of the random cheap coils I’ve tried. It melts cleanly — no weird spitting or burning — and the rosin core flows nicely around joints without you having to wrestle it. I used it on a couple of small component repairs and some LED wires and it grabbed well every time. The wire thickness is spot on for detailed stuff; not too chunky, not so thin that it snaps. The Sn99.3/Cu0.7 mix behaves really predictably once it’s heated, which is exactly what you want if you’re trying not to fry a tiny board. It’s only a 20g roll so you’ll get through it quicker than you’d think, but for little DIY jobs, repairs, or hobby electronics it’s ideal. Just a genuinely nice, easy-to-work-with solder that doesn’t make you regret going lead-free.
Review: soldering on - Bought a handheld portable welder just for beginners and general purpose so required soldering wire thats stable connected and flows melts smoothy, it clearly described for electrical soldering,but its can be used towards other means. Reel smaller than thought and thickness is suitable.above all pruvs value. Ease put to its uses

## Questions & Answers

**Q: Anyone know where I can get a safety data sheet for this please?**
A: Usually, reputable supplier like R/S Components, CPC, Farnell etc will have documents attached with all relevant information. Amazon just sell stuff on behalf of suppliers. It's the suppliers who should give such manufacturers information.

**Q: could this solder be used to solder 28awg wires to usb connectors?**
A: Yes absolutly,make sure the usb connectors are free from any dust which may be present

**Q: New to soldering, do I need seperate flux or is this solder fine to use as it comes?**
A: No need for flux, this solder works perfectly (All in one)

**Q: Can this  be used for stain glass projects**
A: not really too sure but i would not use it you see leaded solder has a little bit of flex to it but this stuff is too hard and needs a higher heat to mealt so i wouldnt use it. stick with lead
