How to Pick the Best Flux Core Welder

A self-shielding flux core welder is a solid choice for people who are just starting to weld, for fixing things around the house, and for professional outdoor welders. One of the main factors to consider when looking for the best rated flux core welder is power. Generally, more power means thicker materials to weld. So, it goes without saying that you ought to think of the type of welding that you will be doing to get the most benefits out of your investment. There are multiple factors to keep in mind when picking the best flux core welder for your needs. Below we will go through some of the most important features to look for in flux core self-shielding welders.

self shielding flux welder properties
  • Input Power

Some flux-cored welders run on 110V or 220V power, and some can run on both. A 110V flux core welder is a good choice if you intend to do most of your work around the house, so you can easily connect to any available household power outlet. On the other hand, a 220V flux core welder is better suited for more demanding tasks or industrial projects. You may also consider going for one with dual-voltage. Generally, a welder with a higher voltage can generate a higher amount of heat; thus, they are able to weld thicker materials.

  • Output Power

The amperage range of welders will give you a clue of just how thick or thin of materials it can weld. Flux core welders alter their amperage along with the wire feed speed, the faster the feed, the more contact; thus, more heat is generated. So a flexible amperage output range is a good choice. However, most flux core welders have a restricted amperage, so this flexibility is a bit limited. That said, not all welders are made the same, so it’s important to read the capabilities of your machine and not solely depend on the numbers.

It’s also important to check the duty cycle. A welder with a 20% duty cycle at 70 amps, means you can weld for two minutes then wait for another eight minutes before welding again. It’s a cycle of a 10-minute set, and it is dependent on the amperage load used.

  • Wire Sizes

Flux-cored electrodes come in different sizes. The most common sizes for light to medium industrial use are .023, .030, .035, and .045. The wire also has a particular classification from the American Welding Society. For example, you may find a standard flux-cored wire as E71T, which is classified as E for electrode, 7 for the minimum tensile strength in 10,000 pounds per square inch of a weld, 1 refers to the ability of welding in all positions, and T refers to the tubular electrode.

If there is a shielding gas, C or C/M will be added to the end of the classification. In this case, C refers to only carbon dioxide, and C/M implies that argon gas can also be used.

  • Making Your Choice

Other features you should consider include thermal overload protection to make sure your machine is running safe, the wire feed speed so it would match your work rate, and portability. Finally, the quality of your machine will make a huge difference in your welding quality and experience. Look for a top rated flux core welder from reputable brands, read the reviews, and always check the warranty. Also, check our best flux core wire welders comparison list, as we frequently update it with newer or better products, in an effort to only feature the best of what the market has to offer. And as always, make sure to have the necessary safety equipment before welding, including gloves and a suitable welding helmet.

The Unique Ability of Flux Core Welders

Flux Core Arc Welders (FCAW) use a tubular electrode, continuously fed through a gun. Heat is then introduced to the continuously fed electrode, melting it, and forming a welding pool. 

Strictly speaking, flux core is a distinct type of wire, which is used within a standard wire feed welder. Its main characteristic is the flux inner core. While MIG welding relies on external shielding gases to protect the weld from contamination, flux core welding relies on the flux coat within the wire. As the flux core wire melts to create the welding pool, the flux coat also melts and acts as a shielding gas.

features and ease of use

The result is a solidified slag, which will need to be smoothed out. Despite that this may sound like extra work, however, it’s actually beneficial as it helps to maintain the structural bonds and properties of the metal. They are also one of the most accessible types of welders to use. They provide great flexibility that no other welder can do, such as welding rusty or painted metals, working outdoors with no external shielding gas, and much more.

Fundamental Uses

One of the primary purposes of using flux core is the ability to weld outdoors freely. It is not affected by the wind even without using an external shielding gas. In addition, they provide a great deposition rate, which yields increased productivity. Moreover, flux core welding works in all positions, flat and horizontal, on a wide range of different materials. They can even work on worn-out welds and protect it from abrasion. Self-shielding flux core welders help remove the impurities of dirty metals that other types of welders can not handle, such as oxidation.

Flux core welders are widely utilized in steel structural projects, such as bridges and buildings. They are also commonly used in ship and vessel construction. Not to mention, they are a great choice for hobby and home shop use, they can be used on pipes, fences, HVAC systems, and much more.

Difference Between Solid and Flux Cored Wires

For wire feed welders, there are two main types of wire to choose from, flux cored and solid wire. Each type has its advantages and disadvantages.

Solid Wire

Solid wire is commonly used for home and industrial projects. In this process, the shielding gas is required to ensure the weld pool remains free of contamination from the environmental elements.

inner flux core
  • Advantages:
  1. Solid electrode wire and shielding gas create a better-looking weld, providing lower spatter levels.
  2. Lower spatter results in less cleaning time.
  3. The arc is soft and less likely to burn through the welding materials.
  4. Great for thin metals.
  5. More forgiving if the operator is somewhat erratic in holding the arc length or providing a steady travel speed.
  • Disadvantages:
  1. Less portable since a bottle of external shielding gas and other additional equipment is required.
  2. This method doesn’t work well in environments prone to wind or breeze.
  3. MIG has a soft arc that will not properly weld thicker materials.
Flux Wire

The difference in flux core and solid wire electrode is the flux coating found on the flux core wire. This coating creates a specific area around the weld pool, which cools much faster than the wire itself. Flux core wire is also called a self-shielding wire, meaning there is no need for an external shielding gas tank.

flux wires
  • Advantages:
  1. They have a high deposition rate, which makes them great for welders who try to maintain low costs.
  2. Flux core wire can also be used on materials that are rusty, dirty, or oily.
  3. Optimal for the outdoors and windy conditions. Portable as there is no need for carrying an extra shielding gas can.
  4. Has deeper penetration properties, thus suitable for thicker materials.
  5. More diverse welding positions such as overhead and directly above due to the coating that cools and directs where the weld pool is concentrated.
  • Disadvantages:
  1. It is not recommended for materials thinner than 20 gauge.
  2. This process creates slag and spatters that may need extra cleaning and sanding.
  3. The settings of the wire and the angle has to be precise.
  4. Produces smoke that makes it hard to see the weld.
