What To Look For When Buying Flux Core Wire?

Now before you walk into the nearby hardware store and start looking for a flux core wire, you need to know that there are different types of flux core wires. Some of them are made from different brands. Each one of them contains different characteristics.

While it is a good thing to have a wide variety, one has to look for some basic components which make these flux core wires the perfect for your use. With that being said listed below are three of the qualities you should keep in buying when buying these wires.

Tensile Strength

When buying a flux core wire it is important to check out the tensile strength of that particular wire. As mentioned earlier, there are different types of flux core wire and each of them has a different tensile strength. So it becomes an important factor to check what your item is rated at.

The tensile strength will determine how much load your wires are capable of withstanding when it is being stretched. This basically depends on what kind of work you plan on doing with the core wires.

In most case the minimum rating of tensile strength is rated at 70,000 PSI. This is basically the standard one should maintain or check before buying any flux core wire.

Shielding Gas

The next thing one has to check before making any purchases of flux core wire is the shielding gas of the wires. Normally there are two types of flux core wires; one of them shields gas while the other one does not shield any gas.

Once again the decision to buy gas shielded or non-gas shielded has to be made by you depending on what kind of work you plan on doing.

If you decide to go with non-gas shielded then there isn’t much to decide. However, if you choose the gas shielded flux core wire then there needs to be a little more decision making to be made.

Gas shielded core wire have different types of gas they shield. This includes CO2 or carbon dioxide. There is also AR and CO2 together.

Using a CO2 basically gives you better and deeper penetration of the object you are welding. On the other hand a mixture of argon/CO2 gives you a good arc quality, less splatter but it will provide less penetration.

Performance

As is the case with almost every product you buy, performance is a key indicator before making any purchases. And once again this will be dependent on the purpose of these flux core wire.

Performance of the wires is crucial because you would always want something that is always giving you the highest output. You cannot exactly determine the performance of the wire you are about to purchase without actually trying them out. However, you can always do a little bit of research on your own with the brand you are option for.

This way you will be prepared for the kind of result you can expect.

Application

One thing we have repeatedly mentioned earlier on is that the purpose of the flux core wire is important when making a decision before buying it. This is because there is a wide variety of flux core wire in the market.

Different kind of flux wire cores are needed for outdoor welding projects. Some are required for applications such as steel structures, while others are used in ship building or the building of bridges. Home owners may want to use them for home improvement projects too.

As a result it is of utmost importance to convey your need and where you want to use the flux core wire to the salesman so that you can buy the appropriate item.

This way not only will you be saving money and not buying unnecessary wire but your welding will be fruitful too.

 With all that being said, we listed below are some of our top picks when it comes to finding to the perfect flux cored wire.

Final Verdict

As we keep mentioning, there are a lot of flux core wire in the market and it can very difficult to find the correct one if you do not have sufficient information.

We have compiled a list of the best flux core wire here that considers all the things one has to consider when making a purchase. This includes the Tensile Strength, the performance of the said wire as well as the application.

Keep in mind that the application is very important as not everyone will buy the flux core wire for the same purpose. Once you get an idea of what or where you will these wires you can consider the other two factors before finally making the call on your purchase.
