Welding is not an everyday task that you can simply do like any other DIY around the house. It is a specialist process and requires the right training, tools and other accessories.

As a beginner in the welding job sector, you must understand the importance of having the best flux core wire and using the right one for the job. Today, we will compare the best flux core wire .030 vs .035 to find which one you should use and why.

Welding is an extremely difficult job for beginners until they discover all the little tips and tricks which only comes with years of working as a welder.

Simply put, welding is the special method of joining two metals together – but, surely,it’s not that simple, is it?

No, it certainly is not!

As a novice welder, the method which is easiest to use is the flux core wire method instead of the MIG. It is much easier and flexible for beginners to get a smooth finish for their welds.

Before you start to get overwhelmed about which is the Best Flux Core Wire out of the many options available, we will make it easier for you to decide.

Today, we will review 3 of the best .030 and .035 flux core wires to change your welding experience for good.

Let’s get going now!

What Is A Flux Core Wire And Its Uses?

Before we jump into reviewing each of these flux core wires individually and discuss their strengths and weaknesses, we must clarify what it is and the uses of it.

A flux core wire, in terminology, is a flux-cored arc welding. It uses an automatic arc process for welding and is a viable option for all types of welding from general manufacture and fabrication. There are two main types of flux core wires which are: self-shielded & gas-shielded. Self-shielded, as the term refers to, doesn’t require any external gas while the gas-shielded wires need it.

So, if it is just another way to weld materials – why the extra peck of interest for beginners in it?

Well, simply put, it is a much more flexible option compared to the more rigid MIG method for welding. When comparing the two methods of using flux core wire or solid wires in MIG, it really depends on the specific job.

For example: if you are working with a thick metal and the job is outdoors, then the best option would be flux core wires. But if you are working with thinner metals indoors then the solid wire MIG method is best.

Quick situations when you should be using flux cored welding wire:

  • When you are new to welding & need to weld a broken metal
  • When you need to work with dirty or rusty metals
  • When you cannot afford expensive welding guns
  • When you are welding outdoors in a breeze or windy conditions
  • When you need to get a welding job done fast
  • When you are welding a metal, which is in an awkward position

Regardless, you must always ensure that you are adhering to a proper safety protocol with any welding project as fire is a very possible hazard.

Now, let’s get the review of the 6 best flux core wires (3 of the size .030 & 3 of the size .035) started with a quick comparison and then we will look at each of them individually.

.030 Vs .035 Flux Core Wire: Which One Is Better For What?

Now, we have covered each of these excellent flux core wires in both sizes in terms of the basics, now let’s get to the verdict – which one is better .030 vs .035!

First of all, it is very important to understand what each of these numbers represent and if you have not become clear by now, it refers to the diameter of the welding rod. These numbers can also be found written as .30 & .35 but meaning the same thing – the thickness of a rod.

When debating which one is better, you will have some welders who will confidently say that one is better than the other – it is just not true! The answer of which one is better is highly dependent on the specific welding project.

Which one is better for what?

.035 welding wires are best for welding metals with thickness of more than 16 gauge and the .030 welding wires are best for any metals thinner than that.

In essence, the thicker the rod the more amp it will require and as a result, it will burn hotter and get a deeper penetration. Consequently, .035 will also be more effective with thicker metals. In contrast, it will be less effective and not suitable for use with thinner metals.

So, if you are welding metals that have thickness of less than .25 inches, then .035 flux core wire is better for you. But if you are welding metals which are thinner than that, then the .030 flux core wire is the better choice. You must realize that the difference is very small and it is the fine line which separate average jobs from flawless ones.

Another thing to consider is your welder. If you have a welder that runs at 210 volts then .030 is the best one. While 250-volt welders will work best with .035 flux core wires.

Things To Consider While Choosing The Best Flux Core Welding Wire

Before you go and purchase your desired flux core welding wire from our best six reviewed here, we will leave you with some of the crucial things to consider. You already know the basics from this review among others, the pros and cons of specific ones, etc. but the following are some things to make your welding process smooth:

  • Why You Are Buying It

One of the first things to ask yourself is why you are actually buying the wire.

Are you an advanced welder with experience, or a beginner who is looking to test the water, or if you are just a complete novice in the welding industry?

Because your ideal choice will depend on your level of expertise.

  • Your Project Type

It is important to define you project accurately and it will make it easy for you to find out exactly what you may need. You will select the product based on your specific project requirements. Every job has specific needs and those are fulfilled by specific tools.

Now, if you are working on a big project which requires expensive flux wires then you will have a proportional budget as well. So, if you are looking to any of the following projects such as:

  • Automobile workshop repairing
  • Industrial construction sites
  • Ship manufacturing welds
  • Or other industrial repairing or manufacturing, etc.

Then, you must consider investing in higher quality materials. These bigger projects or welding jobs with cheaper wires or tools will leave you with a messy result – so consider the type of your project for setting a budget.

  • Your Budget

As we have discussed in a quick point, flux core wires are more expensive compared to the solid MIG wire. So, what you set as your budget is an important factor. You need to make sure you are able to get all your essentials within your budget.

  • Choosing A Trusted Manufacturer

You should always select a manufacturer which is experienced and trusted in industry. This will ensure that you are not left with products which are below standards without any manufacturer warranty or support.

So, it is recommended by experts for consumers to always choose a well-reputed manufacturer which has been working in the industry for many years. This will ensure that you will get reliable & durable products with helpful customer support.

  • Difference Between Flux Core& Solid Welding Wires

As you know, there are some clear differences between the two types. So, depending on your welding machine capacity, the metal you are welding, the condition of the metal, whether you are welding indoors or outdoors, if you are a beginner or an expert welder, you will have to choose the most appropriate one.

There is not a clear answer of which one is better. But if you want a clear one to use for most types of situations then of course the MIG solid wire is the one. However, there are clear advantages of using flux core, as it is easier, more convenient and the best way for beginners to weld.

Advantages of Using Flux Cored Wire

As we already know, there are 2 types of the flux cored welding wires: gas-shielded and self-shielded. Both types are primarily used for arc welding and they produce slag which helps the welding process by letting it cool.

In terms of advantages, there are many such as the fact that flux coating of these welding wires allows it to harden faster than others. This is ideal for welding in awkward positions such as vertical or overhead welding.

The self-shielding flux cored wires do not require an external source of shielding gas because as the flux coating of the welding wire burns, that gas is produced. As a result, they are ideal for outdoor welding jobs. Without the need for shielding gas, welding machines specifically designed for fluxed core welding wires are more compact and portable.

It is not that you cannot use gas-shielded flux cored wires entirely, they are most definitely used and most appropriate for welding thicker metals. They are also great for out-of-position welding jobs and applications.

The popularity of flux cored welding wires is due to its many benefits, the most popular being its effectiveness for use during windy conditions. They are also very much more durable in the face of rusting or debris which is commonly associated with outdoor metals.

Flux core welding wire is definitely a very special type of welding wire with its fair share of benefits to the welding industry. The special filler material and the arc welding method simplifies the welding process.

The following are some other quick benefits:

  • Best for use outdoors
  • Effective regardless of how dirty, rusted, broken or cracked the metal may be
  • Best option for learning or perfecting welding skills
  • Most appropriate for welding metals which cannot be completely cleaned
  • Best for welding over galvanized steel
  • Great option for a low voltage welder to weld thick materials
  • Most economic, affordable and beginner friendly option for effective welding
  • Great for quick welding of thick metals
  • Excellent for awkward positions or out of the ordinary positions welding jobs

Bottom line: Flux core wire is a great choice for a strong, clean & quick weld even by novice welders!

Disadvantages of Using Flux Cored Wire

Now, all things can’t just be perfect about using fluxed core wires, can it?

This is something you may be thinking about and rightfully so, it is best we follow up with some cons for all the pros.

For indoor welding, flux welding wires will not be most suitable because the flux core chemicals will not have natural air to react with as it melts. This will cause a poor welding job. The welding will get cracks or will not hold together at all.

Also, if you are using gas-shielded fluxcorewelding wire, they are much more complicated and not at all suitable for beginners. It is only for heavy duty, expert welding.

Some quick disadvantages or cons to consider:

  • May prove to be more expensive
  • Not suitable for all types of welding
  • Not a complete replacement for solid wire MIG welding

Conclusion

As a beginner in the welding job or industry, you will not be aware of all the techniques in welding as they only come with years of practice and experience on the job. However, a little bit of research can go a long way if you are looking to try out welding.

We have studied the market for the different types of welding wires and tried to settle the debate surrounding the best flux core wire .030 vs .035 – so what do you think, have we got a winner?

Now that you know more about both of these types of flux cored welding wires, you will agree that each of them is specifically manufactured for certain welding jobs and the best one is a conditional statement dependent on a particular job.

Flux core wires are compatible with a wide variety of metals both thick & thin including nickel alloys, stainless steel, low-alloy steel, mild steel, etc. As the first steps, make sure you know which type of metal you are welding, the condition of the metal, the welding environment (outdoors or indoors, windy, etc.) and the capacity of your welding machine to know which welding wire to pick.

For beginners, general welding will be sufficient with the .030 flux core wire and the .035 is more suited to a more powerful welding machine which may not be for novice welders. As a beginner, you will find the flux cored wire method to be most convenient and effective.

Hope you are now more aware and capable of choosing the best flux core wire on your own.
