Synergic Control allows for simple operation by automatically setting the correct voltage/amperage every time, making it highly user-friendly. It offers an impressive 200A output current on dual voltage input for unprecedented efficiency in welding. The TOOLIOM 200M flux core welder is one of the most sought-after welding devices in the market due to its highly advanced synergic control, multi-process functionality, and powerful output current. While flux core welding can produce strong welds, it also has some downsides, such as smoke, fumes, spatter, wire quality, and lack of versatility. Plus, flux core welding is not recommended for thin materials, as the wire can cause warping and other forms of distortion.Īnd don’t forget FCAW requires a particular type of machine, which is not as common as other welding methods, and the process is not as visually appealing as other methods like TIG welding. Low-quality wire can result in a weaker weld or other welding defects.įlux core welding can also produce more spatter than other welding methods, making cleanup more difficult. The flux in the wire creates a protective shield around the weld, but it also makes a lot of smoke and fumes that can harm the welder’s health if proper ventilation is not used.Īnother downside is that the quality of the flux core wire can vary greatly, which can affect the quality of the weld. One downside of flux core welding is that it can produce a lot of smoke and fumes. How To Choose the Best Flux-Core Welderīefore taking the plunge and buying a flux-core welder, decide how you want to use it, and on what materials. Plus, if you add shielding gas to the mix, you might increase the depth of weld. This increases if you up the amperage, with some 200-amp machines hitting depths of 0.375 inches. In general, using a 115-volt welder, you should reach a penetration level of about 0.25 inches. You cannot weld aluminum or other non-ferrous metals. You can weld carbon, mild, stainless and other alloy steels with a flux-core welder. Flux-core is a favorite method of the building industry, as well as transport and large-scale infrastructure projects. The lack of shielding gas means they can operate almost anywhere. What Can I Weld With Flux-Core?įlux-core welders are great when it comes to machinery repairs in outdoor conditions. This is important because a MIG welder deposits about 8 pounds of wire per hour compared to a flux-core welder at 25 pounds per hour. Look for an 8 or 10-inch reel to keep you welding for longer. Most household and lighter-duty MIG welders have a wire diameter of 0.03 inches, whereas if you want to work on substantial material, you need a thicker wire.Īlso, check out the reel sizes, because most MIG welders have a 6-inch wheel, which won’t last that long when you are using the flux-core application. There are subtle differences between MIG welders that offer flux-core capabilities and dedicated flux-core welders. And the third reason is that when speed is crucial, a flux-core welder is much faster. The second reason is that flux-core welding is suitable for any welding position, so it is more versatile. A multi-process MIG welder might be better suited to general welding. So, why buy a dedicated flux-core welder? The first reason is that they can penetrate deeper and they are better suited to thicker material. All you do is swap the electrode and turn off the gas. All MIG welders can perform the flux-core function. You might think that as MIG and flux-core welding are similar in so many ways, that there would be no distinction between when to use MIG and when to use flux-core. This welding method is super-effective when you work with carbon, stainless or low-alloy steels, but it does not work on non-ferrous metals like aluminum.įlux-core welders also generate a lot of heat, so thinner materials like sheet metal and car body panels are also not suitable for this welding method. It depends on what application you are using your flux-core welder for. This is a huge advantage because it means you can perform flux-core in almost any setting and weather condition. What makes it beginner-friendly is the lack of shielding gas. MIG is the easiest method to learn, but alongside that, flux-core takes a couple of hours to understand. Is Flux-Core Welding Easy?įlux-core welding is easier to master than TIG or stick welding. It also differs from MIG because the electrode is hollow. It is very similar to MIG welding in style and process, but unlike MIG welding, which requires gas to protect the integrity of the weld, flux-core welding is performed without such gas. As the wire heats, it melts and releases a gas that protects the weld from oxidation. Flux-core welding is a process that uses a hollow wire electrode packed full of flux, fed through a welding gun into the joint to weld two pieces of metal.
