Review: Electrical Soldering - MUST HAVE! - Used this to Solder some new 6 volt old car battery cable ends. Perfect product for the job and used with “SRA Rosin Paste Flux #135 in a 2 oz Jar” from desertcart too. Only thing I’d like differently is for the thickness to be twice the size, but that’s not their fault I just couldn’t find that size for my application. For the application I was using it for, it still worked great but had to unroll a few feet a couple times to have enough to solder the 2/0 cable ends & cable together. For fine electrical applications such as 16 gauge wire, it would be the perfect size. 3/1/19 update: working perfectly for me Electrical application! I covered the soldered joints with some electrical shrink wrap to keep it from corroding. Review: Great solder, easy to work with. - I have a year old Weller WLC100 40-Watt Soldering Station. I'd been using some solder from Harbor Freight Tools, but I always had trouble tinning my tip. Eventually, it got to the point where solder just rolled off the tip, and it was nearly impossible to transfer heat to make a solder joint. I new it most likely wasn't the soldering iron, and I was afraid I some how had destroyed three different soldering tips through my inexperience. But then I ordered this solder, and right away, it started cleaning off my tip, and I had no trouble at all tinning my tip. Now soldering is a breeze. I can solder an audio connector in a matter of seconds, not the 5-15 minutes it was taking before. So my message is twofold: This solder works very well for both small electronics and larger wires for audio cables (it's thick enough for audio cables, but not ridiculously thick to use on electrical components, like LEDs. And the solder they sell in coils at Harbor Freight Tools is absolute junk. If you're having trouble soldering, try this solder first, before buying a new tip or throwing out your iron, or trying to drip solder on your connections. ## Features - Fine electrical soldering - 60-Percent tin and 40-percent lead - 376 Degree F melting point - 0.062 Diameter. 4-Ounce - Made in Mexico ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00030AP48 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #109,293 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #239 in Solder | | Color | No Color | | Customer Reviews | 4.7 4.7 out of 5 stars (1,995) | | Date First Available | August 29, 2005 | | Included Components | Alpha Fry AT-31604 60-40 Rosin Core Solder (4 Ounces) | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 3.2 ounces | | Item model number | AT-31604 | | Manufacturer | AMERICAN TERMINAL SUPPLY | | Material | Multi | | Part Number | AT-31604 | | Power Source | dc | | Product Dimensions | 6 x 4 x 1 inches | | Size | Pack of 1 | | Usage | Floor | | Warranty Description | UNAVAILABLE | ## Images ![Alpha Fry AT-31604 60-40 Rosin Core Solder (4 Ounces) - Image 1](https://m.media-amazon.com/images/I/81q4xTieexL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Electrical Soldering - MUST HAVE! *by D***S on December 22, 2018* Used this to Solder some new 6 volt old car battery cable ends.

I've used it several times now and have had no problems with it. Everything I have soldered has gone well and worked. What more can you want. I went with this as it is a lead product and I read that lead was easier to work with than the lead free products. I hadn't used either previously so I don't know if that's true or not but I do know it works. ## Frequently Bought Together - Alpha Fry AT-31604 60-40 Rosin Core Solder (4 Ounces) - SRA Solder 135 Rosin Paste Soldering Flux For Electronics, No Clean Flux Made for Lead and Lead-Free Solder Circuit Boards and Copper Electrical Wire - Safe Clean Residues with No Goopy Mess (2oz Jar) - NEIKO 01902 Adjustable Helping Hand with Magnifying Glass, Third Hand Solder Aid, Soldering Wire Station Stand with Dual Alligator Clips and a Heavy Base, Beading & Jewelry Making Tools, Solder Holder --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1746788-alpha-fry-at-31604-60-40-rosin-core-solder-4](https://www.desertcart.tn/products/1746788-alpha-fry-at-31604-60-40-rosin-core-solder-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-17*
