Flux-cored wire welding is a great technique for all welders who often need to weld outdoors or on dirty material. It differs from MIG welding in that it does not require an external shielding gas such as carbon dioxide or argon to protect the weld pool from contamination.
You don’t have to worry about the shielding gas, as shielding gas does not necessarily have to be used with this type of welding. And best of all, it’s an ideal welding process for beginners. As there are many expensive models and the price doesn’t always guarantee quality, we have helped you select 10 of the best flux-cored welders under $200. We’ve selected them based on their welding processes, the voltage, output, duty cycle, accessories provided, warranty coverage, among others.

The flux core welder, as it is called in professional circles, is a type of welding process. Here, the natural oxide layer of the metal is used as its form of protection. This allows thinner, less expensive materials like aluminum and copper to be welded without worrying about oxidation.
Flux-cored wire welding is an arc welding process in which a consumable electrode is used to generate heat. These electrodes are made of flux, filler material, and graphite to create the weld pool. Using these three components can reduce the amount of contaminants in the weld by removing slag and other contaminants from the molten metal during the process.
A flux core welder is a machine that was first invented in the 1930s Trusted Source The History of Welding | MillerWelds Welding has been around since ancient times. Read this article for a brief overview of welding history throughout the years. www.millerwelds.com . It lasted so long because it’s the perfect tool when you need to do welding work on metal parts. This type of welding machine does not require shielding gas and can be used on almost all types of metals such as aluminum, copper, steel, and more.
A flux-cored wire is a special type of wire in the form of a tube. The components of the electrode are on the inside. In the round rolling process, the components are stored in the tube. The embedded powder is responsible for protecting the weld seam – also called slag.
The functionality is initially the same as with most common welding machines that weld with electricity. A short circuit is created. The welding wire is fused with the materials to be welded, creating a weld seam.
In the so-called weld pool, the slag or protective powder floats upwards so that it surrounds the actual weld seam. This ensures protection from the environment and the air. With clean work, the result is a fine and flawless weld seam.
During the welding process, the slag flushes impurities out of the weld seam. Regardless of whether it rains, storms or snows – the weld seam is always protected by cored wire welding. This means that you always get a clean result, and your work is independent of the weather. In contrast to
MIG / MAG welding machines

that work with shielding gas, the slag cannot be removed from the weld seam by the wind.
The special feature of the cored wire welding machine is that a so-called cored wire is used here. A protective layer is formed on the seam by the inner wrapped materials floating to the surface of the weld seam.
On the one hand, this protective layer protects the weld seam from aggressive environmental influences, such as moisture or acid. On the other hand, it prevents oxygen enrichment in particular, as this causes problems in weld seams. If environmental influences act on the fresh weld seam, this reduces the quality. In short: the weld seam is not as corrosion-resistant and durable.
Don’t confuse buying a budget-friendly product with poor overall quality. During our research, we found out that the models that cost more than $200 offer almost the same functionalities as the ones we picked. What differentiates these models are their brand names and maybe the longer warranties. Higher-end welders that cost more than $200 are made by recognized brands such as Lincoln Electric, Forney, and Hobart. But with models that cost less than $200, you’re going to have lesser warranty coverage, but the quality isn’t so average or poor. However, they’re not at par with the higher-end models.
The problem with this type of welder, however, is finding one that will fit all of your needs. So take a look at these criteria:
The flux-cored wire welding machines are a stand-alone type of welding machine. As a layman, one can differentiate between simple and multi-process welding machines:
Before buying a welding machine, you should also look at the operating voltage. Most models can run on 110V, but some dual-voltage welders run on 110/120V or 110/220V such as the SUNGOLDPOWER MIG-190T and TOOLIOM T-135M. However, some machines can work on as many input voltages as possible.
The various filler wires should be usable with all welding equipment. A processable wire thickness of up to 0.8 mm must be possible. There are many factors to consider when choosing a welding wire. The most important considerations include diameter and weld metal quality. For example, cored wires for stainless steel range from 0.8 mm upwards like what you get with common sizes being 1.2 mm, 1.4 mm, or even 1.6 mm.
The amperage usually varies between 85 and 200 amps for this level of welders. The SUNGOLDPOWER MIG-190T can weld with an amperage up to 200 with MMA and 190 with flux-cored MIG. The amperage should be adjustable from 45 amps to 90 amps. When welding with filler wire, it is particularly important to set the amperage correctly. Even with a weld seam thickness of 0.8 mm or more, the amperage should be at least 90, because without enough current your work will not hold together properly and could even fly apart when heated.
The duty cycle is a percentage value over a given amperage. It indicates the welding and cooling time required for precise amperage. For example, the indication 70% duty cycle at 100A means that for 10 minutes of use, it takes 7 minutes of welding and 3 minutes of cooling.
So, the higher the percentage of the cycle, the better and longer the machine can run continuing without overheating. Meanwhile, if you’re choosing a low cycle model, choose one that has overheating protection.
A weight of less than 30 pounds is ideal. Usually, the rule of thumb applies here: the more power, the heavier the device. If you’re going to be welding on the go, choose a compact and portable welder.
Asides from the welder, most welding kits include a lot of accessories so you can weld like a pro or start welding as soon as the package arrives. The welder must come with the welding gun, one ground clamp, one welding helmet, one wire welding brush, and various other accessories.
We said it before, you can’t expect much from these devices. The first reason is the low price and the second is that the brands aren’t that established yet in the market and may not have the means to offer a longer warranty. However, ensure the product has at least one year of warranty and a month of return and refund policy.
