![]() If it doesn't flow and stick you're doing something incorrectly and you need to stop and learn a bit more, and adjust something. One must take a bit of time, relax and understand the details. If you have plumbing Flux and silver plumbing solder, you will fail or damage your device. You can not just make it work with what you have. And all Flux is not created equal, and each type has a purpose. Body oils will prevent solder from sticking. A good condition soldering iron head, clean everything. But they watch videos and see others doing it and can't tell what they did wrong. Most are intimidated from trying at some point and it not working, likely at all. While intimidating to those that have never done it before, it is easy. Of course soldering is the best practical option. There are always alternatives, some better than others. It's resistivity is measured at 15.0 ohm-km, compared to Copper's 17.2, Copper isn't quite as good, From here on epoxy has solder beat in so many ways, I don't have room to list them. I was worried about the current flow so I got the highest silver containing product, (902?) Let's compare. Nearby solder melted and caused me trouble. It's situated on the engine and takes the heat in stride. Silver Epoxy saved me over $4,000 in repairs. I used it to create new wire connections to VVT Actuators that lost all wires to a hungry rat that ate the wires down to the plastic nub. It's most often used in surface mount situations. Silver is a legendary conductor of electricity. Silver epoxy is epoxy with loads of silver filings in it. There are situations where silver Epoxy is required. If you need help picking out some solder fluxes at an electronics store near you, check out our guide on how to choose the right solder paste for your next project.I've used SILVER EPOXY recently and LOVED IT. Instead of experimenting with water, dish soap, or other homebrew methods for cleaning metal surfaces during soldering, pick up a bottle of real flux! It’ll give you much better results in your DIY projects compared to using alternatives that are either impractical or ineffective. If you were hoping to save money by using household items instead of buying proper solder flux paste or liquid solution, you’ll just end up wasting both time and resources when you wind up needing more supplies later on no matter how much Vaseline you try to go through at once. So don’t use it for soldering! Unlike solder flux paste or liquid fluxes, Vaseline won’t do anything to help your solder flow smoothly and make good electrical connections with metal surfaces. While it may stick to things well under normal conditions, it does not function in the same way as solder flux. First of all, Vaseline is petroleum jelly made from hydrocarbons. No, Vaseline should not be used as a flux substitute. This means it’s more likely to oxidize faster and corrode faster. And since you’re working with solder at high temperatures, sudsy residues will evaporate, leaving the metal exposed to the hot solder. Like clean, dry metal surfaces do on their own, the suds from the dish soap may help prevent oxidation during heating (but not as much as true flux). But like water, dish soap doesn’t really provide anything that can improve soldering (at least compared to flux). What about using dish soap instead of flux?ĭish soap is often recommended as a replacement for paste or liquid fluxes, and some people even swear by it as an all-purpose substitute. In other words, the solder will still adhere to the surface just as well if there’s no water present. It can help reduce oxidation during heating on some metal surfaces (nickel and stainless steel), but it doesn’t have any cleaning or wetting properties. Water can be used as a substitute for flux in certain situations, but it has its limitations. You may find it interesting – What can I use if I don’t have soldering wire. ![]() You may end up with some bad-looking joints (not good for mechanical strength), and your solder wire could corrode faster since there isn’t any additional protection provided by the flux. ![]() When the parts are hot enough that the metal starts to melt, it’s more likely to form balls or lumps instead of creating an even coating. Without any type of added flux, solder won’t flow easily to the parts and will adhere poorly. Soldering is possible without using flux, but you’ll often get a poor joint. Keep reading to learn more! Can I solder without flux? But what if you run out of flux or need to do some quick repairs and don’t have any on hand? Are there any substitutes that can work just as well? In this post, we’ll take a look at some alternatives to flux and discuss how well they work. It helps the solder flow smoothly and adhere to the metal surfaces, which results in a strong, reliable joint. When it comes to soldering, flux is an essential ingredient.
