The term “mig wire” refers to a variety of different wires used with metal inert gas (MIG) welding. These wires are coated in materials that create a plasma arc, which fuses the wire with a piece of metal and creates new welds. If you have never worked with MIG welding before, it might seem confusing at first. Each type of wire has its own properties, uses, and limitations. Understanding what kind of mig wire you need for your project is the first step towards getting the job done right the first time. Here’s what you need to know about choosing the best mig wire for your needs.

What Is MIG Welding?
- MIG welding is a type of welding that uses a high-voltage arc to melt the metal, creating a welded joint.
- MIG welding is also known as stick welding because the wire is used in a “stick” shape instead of being coiled like most other types of electrodes. The stick shape allows MIG wire to be more flexible and easier to use than other types of electrodes.
- The arc created by the MIG wire will create a weld in a matter of seconds, rather than the minutes or hours that are needed for other types of welding processes, such as TIG and gas metal arc (GMA) welding. While these two processes take longer to complete, they can produce stronger joints than MIG welding because they use more energy and heat up the metal faster. However, both TIG and GMA require special equipment as well as experience to work with them safely and effectively.
- Since it creates its own electricity through an arc, using MIG wires doesn’t require any additional power source like you would need with TIG or GMA wires or shielding gas cylinders that are used in those processes. This means that you don’t have to worry about an extra expense on top of your project price when using MIG wires for your next project.
Coiled MIG Wire
- Coiled MIG wire is the most common type of mig wire. Coiled MIG wire is available in a wide range of sizes and material types. It is relatively easy to find and can be purchased at any welding supply store.
- Coil diameter ranges from 0.035” to 0.250” in size, with most coils being between 0.120” and 0.150” in diameter. The primary benefit of using a coiled wire is its relative ease of handling and use, especially when compared to other types of mig wires that require specialized equipment such as gas guns or gas-shielded torches for welding applications.
- Coiled MIG wires are available in many different materials, including Aluminum (6061), Stainless Steel (304 or 316), Titanium (Ti6Al4V), and Tungsten (Tungsten Carbide or WC8W). The coating on these wires can be a variety of different materials, including Aluminum Oxide (AO), Titanium Oxide (TiO2), Ceramic Oxide (Ceramic), or Zirconium Oxide (ZrO2).
- Coiled MIG wires are usually coated with an AO oxide coating that offers good weldability and produces a bright bead when using aluminum alloys such as 6061-T6 aluminum alloy for your projects. AO oxide offers good weldability while producing a bright bead, which helps you see the weld joint easier when you are welding.
- Coiled MIG wires are available in different types and grades of coating, with the most common grades being AO-1 (very light), AO-2 (medium), and AO-3 (heavy). The coating on coiled MIG wires is important because it plays a big role in how well the wire works.
- The fine wire is used for small welds, while the medium and heavy wires are better for larger welds. The coated wire should be used for larger welds because it produces a better bead, which helps you see where the weld joint is located when you are looking at your workpiece.
- Depending on the material and coating of your coiled mig wire, they can have different characteristics that affect their performance in certain welding applications or situations. For example, Coated Tungsten Carbide (TiC) wires offer excellent resistance to erosion due to abrasion under conditions of high temperatures and prolonged use as well as excellent resistance to corrosion when exposed to moisture or gases such as hydrogen sulfide or ammonia; these same properties make them an ideal choice for use in welding aluminum alloys such as 6061-T6 aluminum alloy.
Solid-Core MIG Wire
- Solid-core wire is used for MIG welding thicker parts. The solid-core mig wire’s core is thick and contains a large amount of copper. This type of wire has a very low melting temperature, so it tends to be more difficult to work with than other types of mig wires. This can make it more difficult to weld thicker metals such as stainless steel and aluminum.
- Solid-core mig wires are relatively easy to break when they are working at their maximum capacity and are being used in high temperatures. This can cause the welds to become weak, making them more prone to cracking and other problems that can arise from overuse and misuse.
- The solid-core type of wire is not very flexible, which makes it harder to get into hard-to-reach places on the metal being worked on. Because the core is so thick, it also takes longer for an arc with this type of wire than it does with other types of mig wires, which means you have less time between starting your weld and putting down your torch before the weld cools down or breaks apart because you don’t have enough time for an arc before the metal starts cooling down too much or before you hit that point where you need to start your next weld quickly or else you will have problems with your project failing due to overheating or cracking issues that come from overheating in general.
- Solid-core wire is generally more expensive than other types of mig wires and is harder to find in certain parts of the country. This means you might have to go out of your way to find this type of wire at a good price.
Advantages Of Best Mig Wire
Less Shield Gas Required
The most common type of mig wire is made from tungsten. Tungsten is a very strong metal and the one used in migs wires. It can weld hard metals such as steel and cast iron, but it also has its limitations. Tungsten has a high melting point, which means you need to use more shielding gas to prevent it from being cut by the arc. Shielding gas also makes it harder for tungsten to work well with other types of metal. For example, tungsten is not very good at welding aluminum or stainless steel. Using tungsten as your only wire can make it hard to weld a variety of different metals without having to use multiple wires. If you’re looking for the best mig wire for stainless steel welding projects, consider using a different type of mig wire such as tungsten-copper-aluminum (TCA).
Stronger Welds
Tungsten is one of the strongest metals used in welding and cutting tools such as saw blades, chisels, and drill bits. First discovered in 1801 by Karl Friedrich Wöhler, tungsten was used in torpedoes during World War II because they could be made more powerful than any other metal at that time. Wöhler was awarded the Nobel Prize in Chemistry in 1944 for his discovery of this new metal that was easier to produce than gold or platinum due to its higher melting point. Tungsten is also used in the filament of light bulbs and arc welding.
More Consistent Arc and Heat Output
Tungsten has a very consistent arc, meaning it produces a more consistent heat output than other types of wire. A consistent arc is important when welding because it helps you maintain the same speed and pressure throughout the entire weld. This consistency allows you to make larger welds with less effort. The consistency of an arc also makes tungsten a good choice for cutting, as it can produce clean cuts without leaving any spatter or slag on the metal surface.
Stronger Welding Sensitivity
Tungsten is one of the strongest metals used in welding and cutting tools such as saw blades, chisels, and drill bits. First discovered in 1801 by Karl Friedrich Wöhler, tungsten was used in torpedoes during World War II because they could be made more powerful than any other metal at that time. Wöhler was awarded the Nobel Prize in Chemistry in 1944 for his discovery of this new metal that was easier to produce than gold or platinum due to its higher melting point. Tungsten is also used in the filament of light bulbs and arc welding. It has an extremely high melting point (more than 2200 degrees Fahrenheit), which means it can be melted down into a liquid before being cut with an oxyacetylene torch. This fluid form makes tungsten very easy to weld with gas mixtures known as shielding gases.

Tips For Choosing The Right Mig Wire
1. The Wire’s Thickness
If you are using a MIG welder, the wire thickness is extremely important. The thicker the wire, the better it will work. Thicker wires are less likely to melt, but they also cost more. If you need a thinner wire, you’ll want to check out our guide to choosing the best MIG welding wire for beginners.
2. The Wire’s Length
The length of your mig wire is also important when welding with MIG welding machines. When you use thicker wires, like 12 or 18-gauge wires, there will be a lot of metal in between them and your weld joint. This means that there can be more metal around your weld joint and more heat generated during the welding process. If you have thicker wires and especially if they are longer than 3 feet, it can be difficult to hold them in place while laying down your bead or arc on your piece of metal. You may need additional support when welding with long thick wires like these. Look into our guide on choosing the best mig welder for your needs if this is a concern for you as well!
3. The Wire’s Resistance to Heat Damage
The quality of the wire can also impact how well your welds hold up. The thicker the wire, the less likely it will melt under heat. If you’re using a MIG welder and you want to avoid having to change out your welding wires all the time, look for a wire with a lower melting point like 10 or 12 gauge.
4. The Wire’s Resistance to Rusting
The resistance of your mig wire to rusting is also important. If you have already worked with a lot of different types of welding equipment and you have found that one type of wire has always performed better than another, chances are that it was because the type of welding wire had better rust resistance. Look into our guide on choosing the best MIG welder for your needs if this is applicable to your project as well!
5. The Wire’s Resistance to Heat Damage
The resistance of your mig wire to heat damage is also important when comparing different types of welding wires. While barrels are more resistant than rods, rods are still more resistant than wires. Look into our guide on choosing the best MIG welder for your needs for more information!
