Comparison Table: .030 Vs .035 Flux Core Wire
What is flux core wire?
Flux core wire is a type of welding wire which contains flux inside, instead of outside the filler metal. This helps produce a weld without slag (a byproduct that forms on the top) during the welding process as there is no need for an external shield because it's self-shielded (which means it protects itself).
What is flux core wire used for?
Flux-cored wire, specifically for the purpose of handling dirtier materials that may have higher levels of rust, mill scale, or oil.
Flux-cored wire can be used for a variety of purposes including welding to handle dirty and messy jobs without contaminating clean steel or going through high temperatures to weld a thick project.
It's also worth noting that flux core wires typically are smaller than Ox Bronze wires so you can get into tight spaces better without increasing run time.
What is the difference between .030 and .035 wire?
There are two types of wire, .030 and .035. The two types of wire are very similar, but there is a significant difference in the thickness of their insulation. Before the discussion of differences between .030 and .035 flux core wire, let's first cover some basics.
What Is A .030 Flux Core Wire?
A .030 flux core wire is a welding rod that contains a core made of flux. It typically has a small diameter and the number .030 refers to the wire's outer diameter.
These wires are typically thinner than other types of welding rods, which means they can only be used for thin metal sheets, meaning .030 Flux Core Wire won't work with thicker metal sheets. Unlike other types of welding processes, this type doesn't require any external gas containers.
What Is .035 Flux Core Wire?
The number .035 specifies the diameter size, which tells you how thick the welding wires are. The smaller diameter gives more heat than penetrating power, but larger diameters give you intense heat with deeper penetration into the metals being welded together. Generally, flux-core wire is used because it has flux in its center to help as filler when melted down for a smoother welding job.
Now let's take a look at a few of the key differences between the two.
.030 flux core wire
.035 flux core wire
Thinner metals (Less than 16 gauge)
Thicker metals (More than 16 gauge)
Compatible welding machine
Around 50 to 150 Amp Approx.
Around 75 to 200 Amp Approx.
15 to 17 volts Approx.
15-18 volts Approx.
Wire feed speed range
80 to 445 IPM
70 to 305 IPM
There are a few things that you should know about flux core wires. First, the number in front of the letter will tell you what the thickness of the wire is.
The thicker the wire is, the higher the amperage it needs so just make sure your welder can handle it. If you are only welding thin metals then preferably use .030 because it does not need as high amperage.
The other thing to know is that when welding with a flux core wire, thinner materials will burn faster and also melt easier than thicker materials and therefore burn hotter and better penetrates through metal.
When welding anything thicker than 1/2 inch, it's best to get something other than .030 and .035 but if not then try .045 because it will give you a better weld.
Maybe your welder cannot handle anything thicker than .030 and .035 but you can use the appropriate amperage that is recommended by your manufacturer to get good results.
How to Choose the Best Flux Core Wire Between .035 vs .030?
Flux core wire is one of the most important components of a welder. The thickness, or gauge, of the wire will determine which type it is. When choosing your flux core wire you should consider thickness and amperage.
There are many different types of flux core wires to choose from but not all are created equal. Some have thicker gauges than others and some can handle more amps than others. So how do you know what's best for your needs?
We've put together this guide to help you make an informed decision on which type of flux core wire is right for you based on your welding needs.
Choosing the best flux core wire depends on the following matters:
- Welder Capacity
- Project Type and Budget
- Weld shape, size and material
- How Thick Is the Metal you’re welding?
- Are the Joints Straight and Clean or Are They Wide and Variable
- Determine Flux Core Wire for Single Pass or Multiple Passes
- Select the trusted manufacturer
01. Welder Capacity
The higher the welder capacity, the better your machine can weld.
If it's under powered for the job you want to do and you must increase settings in order to use a lower-gauge wire, then your welds will be tricky and take more time.
You'll have to weld in short bursts because the welder temperature is probably too high for that type of wire.
If you use a 210V welder, then .030 welding wire would be your best choice. Expert welders recommend The Forney 42300 x .030 Flux Core MIG Wire for its ability to weld galvanized roofing sheets, as well as auto body sheet metals.
On the other hand, if your welder can support 250 volt watts or more, then you could weld with .035 weld wire. You should consider Blue Demon E71T-11 x .035 for your next job.
The reason for this is simple; you have a larger electrical field. The larger the electric fields the more power your welder can handle without tripping it’s thermal overload protection (commonly called fusing).
So as you can see .030 wires will work on 210V welders but not 250V welders. And .035 wires will work on the 250V welders but not 210v welder.
This is why you need to know your welder’s capacity before making this decision. Don’t just buy .052 welding wire because someone in your welding class has one like it and tells you that .052 is all you need. You could destroy your welder or worse start a fire with too small of wire.
In general you can use .030 welding wire for anything up to 210V welders, and .035 for anything higher than that. If in doubt go by the welder manufacturer’s recommendations. They know their stuff.
02. Project Type and Budget
If you are going to buy a good flux core wire, then make sure that you purchase one for the right project. It is important to consider the following when picking out a specific type of flux wires or cored wires:
- Type of welding job
- Size and shape of welds required
- Alloys included in material
Any person who does not take certain types of precautions will have a hard time producing quality work, so be mindful of these factors when purchasing your next set of wires. Ideally, it all depends on what kind of job you need to complete.
If it is something small like household repair and maintenance, than you can get away with buying cheaper products which do not contain copper or iron materials.
However, if it is something that has higher standards or expectations, then you might have to spend more money.
Be careful what kind of budget you set, because sometimes it can prove very costly if you do not plan accordingly.
The best thing to do is decide how much budget you want to spend and then figure out the project type which will help define your needs.
Flux core wire comes in a wide variety of materials such as:
- Stainless steel wires for shipbuilding or marine use
- Nickel alloys for aerospace equipment
- Copper-based wire for use in electrical work or refrigeration products
- Aluminum-copper alloy for heavy machinery jobs like construction equipment and large scale welds
- Titanium for extremely high heat resistant applications like electrical welding machines and deep sea constructions
It is important to remember that stainless steel flux cored wires are perfect for projects involving, but not limited to, marine and excessive weather conditions. This is because they are fire-resistant and will not melt in extreme temperatures.
Thus, if you need a product that can withstand harsh environments then you should buy flux core wires made of stainless steel or aluminum-copper alloys.
However, copper brings the best electrical conductivity which is ideal for specific projects such as electric machines and appliances like generators.
Conversely, copper-cored wires are popular for electrical applications such as household projects.
In addition, Aluminum is best for welding materials like steel and heavy equipment – but it will not conduct electricity well.
03. Weld shape, size and material
As we have said before, project type is essential to use the right flux core wire which will fulfill the requirements of a specific weld:
Stick flux core wire is best for general construction projects like ship building and pipe welding.
It will also work for electrical work, air conditioner repairs or light industrial jobs like construction equipment manufacturing. However, it cannot be used with gases other than inert ones like argon or helium.
If you are going to use solder-free fixes (liquid flux) and you need to join a metal, then stick flux core wire will be the best option for you.
This type of wire comes in three different diameters: 0.030", 0.035" and 0.045".
While the first one is great for household repairs, the latter two can be applied to bigger projects like shipbuilding.
On the other hand, solid flux core wire works best for high-stress applications or heavy machinery like cranes and large-scale construction equipment.
Since it is denser than stick wires, this type of cored wire requires a much higher voltage and amperage.
The main downside is that it cannot be used with gases, so you can just use electrodes or tips to direct the flow of current.
You should also know that solid flux cored wires come in two different shapes: 0.030" and 0.045".
This type of wire is not suited for household projects, so it is better to stay away from them if you are not a professional.
04. How Thick Is the Metal you’re Welding?
Choosing the right welding wire for your project is crucial. For thin mild steel, choose .030 flux core wire, but if you're working with thicker metals around 1/4 inch and up then it's a good idea to use .035 flux core wire.
It is important to match the thickness of weld metal to that of the workpiece material in order to maintain or create required mechanical properties after joining.
Combination welding can be used when both pieces are about the same thickness.
When joining plate workpieces that differ greatly in thickness some stress concentrations may result from the welding process. In this case it is important to ensure that a suitable filler wire for both parts can be obtained.
05. Are the Joints Straight and Clean or Are They Wide and Variable
I've been welding for about fifteen years and I never looked at joints as anything more than "just weld it" until a few months ago. That's when one of our welders showed me the joint types and how they affect the quality of your final project.
It turns out that there are two main types of joints: wide & variable or straight & clean. You need to know what kind of joint you're dealing with because that affects how you prepare your project for welding.
Wide-variable joints require extra filler metal, such as .035, which means that your welder should be able to melt it easily. Straight-clean joints only need about .035, which is a lot easier to work with.
06. Determine Flux Core Wire for Single Pass or Multiple Passes
One of the most important parts of welding is selecting the right wire for the job. It's best to determine if you are using a single-pass wire or a multiple-pass wire, depending on what your welding needs are.
A single-pass wire should be used when welding with one pass (such as overhead welding).
On the other hand, a multiple-pass wire should be used when welding with more than one pass (such as pipe welding).
If you use a single-pass wire for multiple passes, it could lead to cracking and failing welds. Seek out the specifications for each type of wire from the manufacturer.
07. Select the trusted manufacturer
Welding wire is a type of consumable that you need to buy for your welding projects, so you should take your time to find the right provider.
Welding wire manufacturers vary in price range and quality, so it's important that you study them carefully before making a decision.
Those who are new to welding should rely on their local supplier for recommendations or ask a relative who welds regularly about a reliable company.
The most important consideration when buying welding wire is whether you need .030 or .035 gauge wire. This will depend on the thickness of material the wire needs to penetrate and the amount of current available in your power system.
Electrical conductivity is another factor to consider. It measures the ease with which electrons flow through a material, and it's an important consideration when you're choosing welding wire for carbon steels due to their high tensile strength.
Which is the best flux core wire for your next project?
Do you need flux core wire for your next project?
Flux-cored wires are a type of welding rod that uses an electric arc to melt metal.
The process can be used with any type of metal, but it's most commonly used on steel and aluminum.
It's also often used in manufacturing plants because it doesn't require ventilation like other types of welding rods.
If you're looking for something that will last longer and provide more consistent results than traditional welding rods, then this might be the right choice for you.
Check out our guide below to learn more about what makes these wires so great.
One thing to know about flux core wire is that there are two major size ranges. One is .030 and another is .035.
For our review, the 3 of each were selected because this gives something a bit more proportional to most jobs.

03. Forney 42300 Flux Core MIG Wire Review
- All position flux core MIG wire for mild steel that is a self Shielded and works well on rusty, dirty and painted Material
- Best suited to single pass applications with high travel speed, runs hotter than solid wires
- Excellent for outdoor windy conditions
- Click on the (BY FORNEY) name above in blue under the title to view our full catalog of Welders, Abrasives, Chain/Wire Rope, Tools and more!
The Forney 42300 Flux Core MIG Wire is a self-shielded, all-position flux-cored MIG wire.
This type of wire does not require gas shielding but works best outdoors in windy conditions and can be used for single-pass applications only.
It's considered ER71T-GS which stands for Electrode, the tensile strength is 79,000 PSI and polarity is DCEN Straight.
The diameter of this particular wire is .030" (.762 millimeters) and the weight is 2 lbs. (.907 kg).
Moreover, this wire is meant for general purpose applications and not specifically designed for a specific range of applications.
While the DCEN polarity usually requires more voltage than the straight polarity in order to get a solid arc, this wire does not require it so that you don't have to bring your CURRENT setting on your TIG welder down as low as possible.
We would like to give you an example scenario with this welding wire. You are doing some welding where windy conditions will be present (this includes outside work) and you need something that is good quality, has good coverage without needing too much heat or deep penetration power, doesn't break easily due to high travel speeds, and can be used effectively with just one pass, then this Forney 42300 Flux Core MIG Wire is the way to go.
As we all know, the most important factor when welding is making sure that you have the correct amount of shielding gas for your situation and scenario.
This Forney 42300 Flux Core MIG Wire is not made to be used with gas shielding so you will have to rely on air as your shield.
The easiest and most reliable way of doing this would be to just weld in an area that is well-ventilated, open and has little or no wind at all.
As it was previously stated, the DCEN polarity doesn't usually require less voltage than straight polarity but you should bring your CURRENT setting down a low level as possible because it does work better when the current is lower.
When using this wire with other applications besides MIG welding such as a stick or TIG welding, for instance, make sure that you use it in a well-ventilated area that is wind-free.
We also would like to mention that it's important to be very careful when using this wire and keep your distance from the weld zone because it does create a lot of sparks due to high travel speeds.
A negative for this, if you're not cautious about the cleanliness of your materials, you'll find that the welds will be less than ideal. The Forney 42300 wire will create some pretty good welds, but if you're not careful they can be a little inconsistent in their appearance.
This is the case because the material that's used in this type of electrode has more internal contaminants than other types and it has to work really hard to remove them during the welding process.

Which should you use for your project - .030 or .035?
You should ask yourself how thick your metal is so you can choose if you need .030 or .035 flux core wires. Thinner material should use .030 flux core wire and thinner material as well as thicker material should use .035 flux core wires.
The difference between these two sizes of the flux core wire is .005" and that is not much but it's enough to make a durable weld.
If you use thinner material with the thicker or .035 flux core wire then you will get a better penetration. Moreover, if you used the thinner .030 flux core wire so if you have thin material to be welded then it is best to use .035.
The thicker the metal you are welding, then the more of a gap that there should be between the two pieces of metal, and with thinner materials as well as thicker, the same amount of a gap of .005" is ideal.
When welding with a flux core welder, you should make sure that the pieces of metal are clamped tight together and there is enough penetration so no air gaps exist.
This can be done by using the appropriate size of wire as well as having the right gap welded into it while keeping in mind that thinner material should use.030 flux core wire and thicker materials should use.035 flux core wire.
If you use too thick of a wire, or if you have too much distance between the two pieces of metal, there will be no penetration through the material at all and the only weld from the outside which is not good because you want it to go as deep as possible for better results.
The thicker the metal, the more you should avoid using a .035 flux core wire because it will not have enough penetration to make a weld that would be able to hold up under pressure and stress.
If you use too thin of a piece of metal then you shouldn't use .030 either just because in order for you to get the proper penetration, the temperature is not hot enough and it will melt easier than .030 which can be used in a wider variety of situations.
Whether you are repairing a car, fixing up an old project or starting a new one, the right flux core wire can make your job easier and more enjoyable. We hope that our guide has helped you learn about both .030 vs. .035 flux core wire, as well as how to choose the best flux core wire for your next project.
Can you use .030 wires with a .035 tip?
No, you should never use .030 wires with .035 tip. Because it will drive you just like crazy.
How thick can you weld with .030 wires?
It can weld up to 1/4
Does flux core wire go bad?
Flux core wire is not solid, so moisture can enter the wire. So, if a flux core wire is exposed to moisture or contaminants for too long, it will deteriorate. The longer the wire is in contact with those elements, the faster it will go bad.
What are the different types of flux core wire?
There are two variations of flux-cored wires: • Gas-shielded • Self-shielded. Self-shielded flux-cored wires require external shielding gas and have the slag easy to be removed. Consider using this wire when welding on thicker metals or in out-of-position applications. The self-shielding flux core wire contains its own shielding, which may be a positive for some since it's portable. However, this type of wire can also cause sparks and emit dust so clothing should be kept away from the welding zone.
How to maximize the lifespan of welding wires?
If you want your expensive, high-quality welding wire to last as long as possible, it's important that you keep it sealed and dry at all times (never store them in humid environments such as a wet basement or outdoors). Welding rod life also varies depending on the type: some consumables are stamped with an expiration date which means that they lose their characterizing properties before time expires; other types of the rod are not dated and may continue to meet performance standards after the marked date or the shelf life is over.
Can I use shielding gas with self-shielding flux core wire?
Yes, you can use shielded gas with self-shielding flux core wire. While it is not necessary to use an external gas tank, the shielding gas can provide added protection against moisture and oxygen. When using self-shielding flux core wire, start by selecting a larger diameter size than you would normally use with regular shielded wire. As with normal shielded cable, a smaller diameter may be used if desired for welding fine details.
