Perfect Soldering Performance This low melt solder wire has excellent soldering capability due to its low melting point which allows for shorter soldering time resulting in clean and smooth flow. It produces highly durable electrical connections that do not crack even on difficult surfaces while resisting spattering, corrosion, heat fatigue, and oxidation producing minimal slag and smoke. It is also compatible with most soldering irons and equipment.WARNING：This product contains LEAD, which may cause cancer.

Low melting point and strong connection. This is a great product to use and learn to solder with. Securely holds without difficulty and does not run . Very accurate solder points. Review: Good solder, just wish the roll was bigger - Been using this for small electronics work and it’s been performing well. The solder flows nicely and the rosin core does a good job helping the joints wet properly. The 0.8mm size is a good middle ground for most of the soldering I do, from small components to general wiring. My only complaint is the roll size. It’s a 50g spool and I wish they offered a 100g version since I tend to go through it pretty quickly. Other than that it’s been solid quality. ## Features - High-quality: High Purity Tin 63%-Lead 37% (Sn63-Pb37) ratio soldering wire is the most commonly used type of solder for electrical soldering. - Easy to use: 0.8 mm diameter and 50 g weight.Prefluxed with 2% continuous flux rosin core, no additional flux needed. - Perfect Soldering Capability: Low melting point, flow smoothly, fast soldering speed and strong solder joints. - Versatile Applications: Our tin lead electronic solder is suitable for a wide range of uses, such as home appliances, circuit boards, mobile phones, computers, instruments, and DIY projects. - Warranty: Our solder has 1-year warranty period.

What is the optimum melting point for solder?** A: Soldering iron tip temperatures are commonly between 600-650°F for leaded solder, And This is 63/37 rosin core solder with a eutectic point at 361 degrees Fahrenheit. Therefore, a 60 W soldering iron can easily melt this solder wire. **Q: What are the dimensions of the solder reel?** A: The diameter of the solder reel is 56mm and its height is 16mm. **Q: Can this solder be used on car electrical panel boards?** A: Yes, this soldering wire with flux is suitable for a variety of applications including electronic and electrical soldering, printed circuit board assembly, RC car and drone building, guitar repair, jewelry making, wire splicing and other DIY hobbies. **Q: Do I have to clean off the flux after soldering with this solder?** A: The flux core solder wire is corrosive and should be cleaned from soldered connections with isopropyl or rubbing alcohol after cooling. The rosin flux is not a "no-clean" flux. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very manageable wire for electronic needs *by M***N on 25 March 2026* Thin and easily manageable for circuit boards and led strip use.

Very accurate solder points. ### ⭐⭐⭐⭐⭐ Good solder, just wish the roll was bigger *by R***K on 6 March 2026* Been using this for small electronics work and it’s been performing well.

Not as good for PCB circuit boards. *by I***R on 11 February 2024* This is a great solder for the price. But I've never used 63/37 solder, only 60/40. I experienced a problem, although I can't determine what the cause of the problem was. In my case, on a new circuit board I was soldering, the JWOWO solder climbed up my electrical parts, effectively soldering them, but not wetting out and making a connection to the clean and new PCB circuit board. So, comparing this to Radio Shack and also X-Tronic standard 60/40 solders that have about 2% Flux (X-Tronic is listed at 1.8% Flux and 60/40 ratio of lead) the 63/37 JWOWO had some problems. It may not be the solder that is the problem. But I wanted to report it, nonetheless. I've never seen any of my solders (not even the really bad no-name stuff from Harbor Freight) that didn't stick to a circuit board. I had to actually use the X-Tronic solder because on several solder joints, the JWOWO solder would rapidly wet out and cover a transistor, but none of the solder would actually go onto the PCB. It may have been a temperature problem. It may have been something I did wrong. But I have never seen solder actively resist and not wet out or "tin" a clean PCB that was freshly cleaned with 90% isopropyl alcohol. My advice is to try this, and use it for a specific application. But test it first. I will definitely keep using this solder on copper and tin plated wires, because it flows out beautiful, and works perfectly on wire connections. Just test the solder first, and make sure it works well with the alloys you're soldering. In the future, I'm going to switch to Kester 44 63/37 solder with 3% flux (heavier amount of flux) and see if that makes any difference on the small circuit boards. The JWOWO is 2% flux. ## Frequently Bought Together - Rosin Core Solder Wire for Electrical Soldering(0.8mm/50g),By JWOWO - 2 Jar Solder Flux, Flux for Soldering, Rosin Soldering Flux Paste for Lead-Free Electronics Soldering and Soldering DIY (1.2oz/35g in a Jar) - Liquid Solder Flux Dropper (30 ml/1 Oz.)
